SAFETY INSTRUCTIONS

ELECTRICAL SAFETY
WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:  You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets, and any other connectors for wear or damage. You must ensure that the risk of electric shock is minimized by the installation of appropriate safety devices. A Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a Residual Current Device (RCD) be used. It is particularly important to use an RCD with portable products that are plugged into a supply that is not protected by an RCCB. If in any doubt consult a qualified electrician. You may obtain a Residual Current Device by contacting your Siegen dealer. You must also read and understand the following instructions concerning electrical safety.

1. The Electricity at Work Act 1989 requires that all portable electrical appliances, if used on business premises, are tested by a qualified electrician, using a Portable Appliance Tester (PAT), at least once a year.

2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances and the safety of the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.

3. Ensure that the insulation on all cables and on the appliance Is safe before connecting it to the power supply. See 1.1.1. and 1.1.2. and use a Portable Appliance Tester.

4. Ensure that cables are always protected against short circuits and overload.

5. Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that none is loose.

6. Important: Ensure that the voltage marked on the appliance matches the power supply to be used and that the supply is correctly fused.

7. DO NOT pull or carry the appliance by the power cable.

8. DO NOT pull the plug from the socket by the cable.

9. DO NOT use worn or damaged cables, plugs, or connectors. Immediately have any faulty item repaired or replaced by a qualified electrician.

10. This Mig Welder S0863 is a single-phase machine and must be run from a minimum 16amp supply. To achieve maximum output this model will require a 30Amp fused supply. We recommend you discuss the installation of an industrial round pin plug and socket with your electrician.
    Fit a plug according to the following instructions (the UK only).
    a) Connect the GREEN/YELLOW earth wire to the earth terminal ‘E’.
    b) Connect the BROWN live wire to the live terminal ‘L’.
    c) Connect the BLUE neutral wire to the neutral terminal ‘N’.
    d) After wiring, check that there are no bare wires, that all wires have been correctly connected, that the cable outer insulation extends beyond the cable restraint and that the restraint is tight.

11. When a cable extension reel is used it should be fully unwound before connection. A cable reel with an RCD fitted is recommended since any product which is plugged into the cable reel will be protected. The cross-section of the cable on the cable reel must be suitable for the unit and never lower than the cross-section of the main cable supplied with the unit.

ASSEMBLY & PREPARATION

ASSEMBLING GAS PLATFORM: (Refer to ‘P’ in figs.1 & 2) Turn the welder upside down on a smooth non-abrasive surface. The welder should be turned over by two people as it is very heavy.

1. The gas platform is held in place with 7 M6 x 10mm bolts requiring a 10mm spanner. The casing has pre-prepared threaded inserts ready to take the fixings. Place the platform onto the base of the welder with the axle uppermost and fix in place with 3 bolts. See (X) in fig.1 below.
2. Insert the remaining four bolts through the two fixing flanges laying on the back of the welder. See (X) in fig.2. Finally, tighten all 7 bolts.

ASSEMBLING THE WHEELS: (Refer to fig.1)

1. Slide a wheel (Y) over each end of the solid axle attached to the gas platform. Slide a washer over each end of the axle and insert a split pin (Z) through the hole in each end of the axle and bend it over to retain the wheels.
2. Bolt the two castors (W) to the front end of the base using the 8 bolts provided. The casing has pre-prepared threaded inserts ready to take the fixings. See fig.1.
3. With the assistance of another person turn the welder the right way up onto its wheels.

ASSEMBLING THE EARTH CLAMP: (Refer to fig.3) Feed the eyelet on the end of the earth lead through the hole in the clamp arm as shown in fig.3A.

1. Drop the eyelet over the terminal and firmly fix it with the bolt provided as shown in fig.3B.

INSTALLING THE GAS CYLINDER. The welder is designed to accommodate small or medium-sized gas cylinders up to a maximum height of 1000mm. Contact your local Gas dealer for supply.

1. Place the gas cylinder onto the rear platform of the welder. See fig.2-P. Place one end of the fixing chain into one side of the retaining bracket. Draw the chain around the cylinder and place it into the slot on the other side of the bracket leaving as little slack in the chain as possible.

ATTACHING THE REGULATOR. Whichever gas you are using it is advisable to ‘crack’ the cylinder valve before attaching the regulator. This means opening and closing the valve very quickly in order to blow away any dust and dirt that may have accumulated in the gas outlet. Stand to one side whilst doing this.

1. CO² GAS. Ensure that the threads on the gas bottle are undamaged and free of oil and grease before attaching the regulator. (Oil or grease in the presence of high-pressure gases can be explosive). Ensure that the regulator has an undamaged gasket fitted. The regulator will screw directly to the threads on the gas bottle. Tighten with a spanner.
2. ARGON GAS OR ARGON MIxTURES. Cylinders containing Argon gas and Argon mixtures have a female thread and will require the use of a Bull Nose Adaptor to attach the regulator to the cylinder as indicated in fig.4. Ensure that the threads on the gas bottle are undamaged and free of oil and grease before attaching the regulator. (Oil or grease in the presence of high-pressure gases is explosive). Fit the Bull Nose Adaptor to the cylinder first and tighten with a spanner. Ensure that the regulator has an undamaged gasket before fitting onto the Bull Nose Adaptor. Tighten with a spanner.
3. Slide a clip over each end of the gas hose supplied. Push one end of the hose onto the regulator outlet and the other end over the gas inlet spigot on the back of the welder. See fig.2G. Tighten the clips to ensure a good seal.
4. Close the regulator valve by turning it anticlockwise before opening the cylinder valve. Stand to one side when opening the cylinder valve.
5. Set the regulator flow rate to 5-8 liters/min depending on the material to be welded, and whether there are draughts that are strong enough to disturb the gas flow.
   

CONNECT THE TORCH CABLE TO THE WELDER. Align the pins on the Euro connector with the socket on the welder front panel as shown in fig.5. Push the connector into the socket and rotate the locking ring (A) clockwise so that it draws the plug into the socket as shown in fig.6.
Note: damage to torches and cables is not covered by warranty.

FITTING A 15KG REEL OF WIRE. Ensure that the wire diameter used is matched by the correct groove size in the drive wheel and the correct tip size on the torch as well as the correct torch liner. Failure to do this could cause the wire to slip and/or bind.

1. Unscrew the locking knob from the end of the spool holder (see fig.7C) and remove the spacer (B). The spacer is not required for 15kg reels of wire. Slide the reel of wire onto the spool holder and ensure that the clutch pin at the back of the spool holder (E) engages into the guide hole in the wire reel molding. This will prevent the wire reel from freewheeling on the spool holder. Ensure that the wire is coming off the bottom of the reel in the direction of the wire drive unit as shown in fig.8 below.

FITTING A 5KG REEL OF WIRE. Ensure that the wire diameter used, is matched by the correct groove size in the drive wheel and the correct tip size on the torch as well s the correct torch liner. Failure to do this could cause the wire to slip and/or bind.

1. Unscrew the locking knob from the end of the spool holder (see fig.7C) and remove the spacer. Slide the reel of wire onto the spool holder and ensure that the clutch pin at the back of the spool holder (E) engages into the guide hole in the wire reel molding. This will prevent the wire reel from freewheeling on the spool holder. Slide the spacer onto the spool holder and retain it by screwing the knob into place as shown above in fig.9. Ensure that the wire is coming off the bottom of the reel in the direction of the wire drive unit as shown in fig.10.

FEED WIRE THROUGH TO TORCH. Referring to fig.12 open the wire feed mechanism by pushing the locking/wire tension knob (1) down to the right allowing the pressure roller carrier (2) to spring up revealing the feed roller. Ensure that the required feed groove (0.6 or 0.8) is in line with the wire path. See Section 3.12 on how to reverse or change the roller.

1. Release the wire from the reel and cut off any bent portion ensuring that there are no burrs left on the end of the wire. Keep the wire under tension at all times to prevent it from uncoiling.

2. Straighten about 40-50mm of wire and gently push it through the flexible metal-sheathed cable (3) and through the 6 or 8mm feed roller groove and on into the torch cable liner.

3. Push down the pressure roller carrier onto the wire feed roller and hold it down. Lift up the locking/wire tension knob so that it enters the slot in the pressure roller carrier and snaps into the indent in its top surface. See fig.13. Rotate the tension knob to a medium setting i.e. between 2 and 3.

4. Remove gas cup (fig.11-2) and contact tip (1) from the end of the torch as follows:
   a) Take the torch in the left hand with the torch tip facing to the right.
   b) Grasp the gas cup firmly in your right hand.
   c) Turn the gas cup clockwise only and pull it off the end of the torch tip.
    WARNING! do not turn the gas cup anti-clockwise, as this will damage the internal spring.
   d) Unscrew copper contact tip (right-hand thread) to remove.

5. Check welder is switched off “0”, and that the earth clamp is away from the torch tip. Connect the welder to the mains power supply and set the voltage switch to one.
   
   

6. Set the wire speed knob to position 5 or 6. Keep the torch cable as straight as possible and press the torch switch. The wire will feed through the torch.

7. When the wire has fed through, switch the welder off, unplug from mains.
   a) Take the torch in the left hand, slide the contact tip over the wire and screw it back into place.
   b) Grasp gas cup in right hand, push onto torch head and turn clockwise only. Do not turn the gas cup anti-clockwise, as this will damage the internal spring.
   c) Cut wire so that it is just protruding from the cup.

SETTING WIRE TENSION. Adjust the wire tension by rotating the wire tension knob. Turn clockwise to increase the tension and anticlockwise to decrease the tension. See (1) in fig13.
IMPORTANT: Too little or too much tension will cause problematic wire feed and result in poor welding.

1. The tension between rollers is checked by slowing down the wire between gloved fingers. If top feed roller skids the tension is correct. Use as low tension as possible, too high a tension will disfigure the wire and result in a blown fuse.

CLUTCH ADJUSTMENT. Note: It is essential that the clutch is adjusted correctly.

1. Once the wire is fed through the torch, switch on the machine and set the wire speed to maximum.
2. Depress torch switch and release quickly. If the spool overruns it indicates that the clutch is too loose.
3. Tighten the clutch nut located in the center of the wire spool holder with a spanner (fig.7-D) and test the machine as above until the wire stops overrunning.
   Note: DO NOT over-tighten the clutch as this will cause wire feed problems and strain the motor.

TURNING/CHANGING THE DRIVE ROLLER. (See fig.14) Ensure that the wire diameter used is matched by the correct groove size in the drive wheel and the correct tip size on the torch as well as the correct torch liner. Failure to do this could cause the wire to slip and/ or bind.

1. Referring to fig.12, open the wire feed mechanism by pushing the locking/wire tension knob (1) down to the right allowing the pressure roller carrier (2) to spring up revealing the feed roller.
2. Referring to fig.14, loosen and unscrew the black feed roller retaining knob (C) and put it to one side.
3. The roller carrier (A) is keyed to the main drive shaft and the drive roller (B) is keyed to the carrier, see below. Place a finger onto the end of the driveshaft to prevent the carrier from moving and slide the drive roller off the carrier with your other hand.
4. The size of each wire feed groove is printed on the edge of the roller on the same side as the groove.
5. Turn the roller over to use the other groove or use a roller with different-sized grooves as required. The groove to be used should be positioned furthest away from you to be in line with the drive path.
6. Check that the key in the carrier (A) is properly seated in its slot. Ensure that the slot on the inside face of the drive roller (B) is aligned with the key and slide the roller back onto the carrier.
7. Screw the black roller retaining knob (C) back onto the end of the driveshaft and tighten.

MIG/MAG WELDING

A spool of welding wire is positioned on the welder’s spool holder and automatically fed through an insulated liner in the torch to the tip. The torch assembly consists of a switch, liner, gas hose, and control cable. The switch activates the wire feed roller and the gas flow. Conversely, releasing the switch stops the wire feed and gas flow. The weld current is transferred to the electrode (the wire) from the contact tip at the end of the torch. A gas cup fits over the contact tip to direct the gas flow towards the weld ensuring that the arc welding process is shielded from oxidizing air contaminates. The shielding gas also assists in heating the weld materials. The torch is connected to the positive side of a DC rectifier, and the negative clamp is attached to the workpiece.
IMPORTANT: Should you have no welding experience, we recommend you seek training from an expert source to ensure your personal health & safety. Good Mig welding may be achieved only with continued, supervised practice.

PREPARATION FOR WELDING
IMPORTANT: BEFORE YOU COMMENCE, MAKE SURE THE MACHINE IS SWITCHED OFF AT THE MAINS. IF WELDING A CAR, DISCONNECT THE BATTERY OR FIT AN ELECTRONIC CIRCUIT PROTECTOR. WE STRONGLY RECOMMEND THE USE OF A Sealey “PRO SAFE/12V OR 24V IN ORDER TO PROTECT SOPHISTICATED ELECTRONICS. ENSURE YOU HAVE READ & UNDERSTOOD THE ELECTRICAL SAFETY INSTRUCTIONS IN CHAPTER 1.

1. Connecting the Earth Lead.
   To ensure a complete circuit, the earth lead must be securely attached to the workpiece that is to be welded.
   a) Best connection is obtained by grinding clean the point of contact on the workpiece before connecting the earth clamp.
   b) The weld area must also be free of paint, rust, grease, etc.
   c) When welding a vehicle, be sure the vehicle battery is disconnected or fit an Electronic Circuit Protector available from your Sealey dealer.

2. Power Output switch. Set the switch to position 1 or 2 for welding up to 2mm thickness. Use settings 3,4,5,6. for thicker welds.

3. Setting the welder controls. In principle, the lower the amperage required, the slower the wire speed. See the setting chart below for voltage and corresponding wire speeds.
   Note: these settings are only a guide and will vary according to the operator’s experience.

4. Welding mild steel.
   To weld mild steel you can use CO² gas for most tasks where spatter and the high build-up of weld do not pose a problem. Welding with a long arc reduces penetration and widens the arc. This in turn results in more spatter. A long welding arc can be appropriate for welding butt joints in thin materials. Welding with a short arc, at the same weld settings, results in greater penetration and a narrower weld and reduces the amount of spatter. To achieve a consistent spatter-free and flat weld, you must use an Argon/CO² mixture.
   

5. To weld aluminium use:
   √ Argon gas,
   √ 0.8mm Contact Tip,
   √ 0.8mm Aluminium Wire,

6. Overload Protection. Thermostatic overload protection is provided.
   When an overload has occurred, leave the unit to cool. The thermostat will automatically reset the unit when the temperature has returned within limits

7. Spot Welding. Spot welding may be carried out as shown in fig.16.
   It will be necessary to fit a spot welding gas cup.
   (a) Overlapping metal sheets with a maximum thickness of 0.8 mm may be welded as indicated.
   (b) Alternatively they may be welded edge to surface as indicated.
   (c) For thicker sheets pre-drilled holes may be employed.

8. Use the wire feed control in conjunction with the spot weld timer beside it. To activate the timer turn the knob clockwise. The settings indicated in the black portion of the chart are for guidance only and may vary with operators’ experience.

RATING PLATE

7. Mains Supply
   U1: Rated supply voltage and frequency.
   Imax: Maximum current.
   I1eff: Maximum effective current.

8. Welding current range.

9. Serial Number. Specifically identifies each welder.

MAINTENANCE

1. WIRE FEED UNIT Check the wire feed unit at regular intervals. The feed roller wire guide plays an important part in obtaining consistent results. Poor wire feed affects welding. Clean the rollers weekly, especially the feed roller groove, removing all dust deposits.
2. TORCH Protect the torch cable assembly from mechanical wear. Clean the liner from the machine forwards by using compressed air. If the liner is clogged it must be replaced.
3. CHANGING FEED ROLLER (See Section 3.12)
4. CONTACT TIP The contact tip is a consumable item and must be replaced when the hole becomes enlarged or oval. The contact tip MUST be kept free from spattering to ensure an unimpeded flow of gas. Refer to fig.11 and section 3.9 for removal and replacement.
5. GAS CUP The gas cup must also be kept clean and free from spattering. Build up of spatter inside the gas cup can cause a short circuit at the contact tip which will result in either the fuse blowing on the printed circuit card or expensive machine repairs. To keep the contact tip free from spatter, we recommend the use of Sealey anti-spatter spray (MIG/722308) available from your Sealey Dealer. Refer to fig.12 and section 3.9 for removal and replacement.
6. REPLACING THE LINER Wind the wire back onto the spool and secure it. Unscrew the torch from the machine and undo the brass nut. The liner should now be visible. Pull it out and replace it with a new one.
