ASSEMBLING THE WELDER

Make sure the power supply information on the machine’s rating plate is compatible with the power supply you intend to connect it to.

A suitable plug must be fitted by a qualified electrician.
This machines wiring has insulation stripped in preparation for wiring a 16A plug (not supplied).
It is designed for connection to a 16amp power supply rated at 230V AC.
Because it is constructed mostly of metal parts, it is a Class 1 machine; meaning, it must have an earth connection in the power supply. This is to prevent electrocution in the event of a failure.
Note: Remove the plug from the socket before carrying out adjustment, servicing or maintenance.
Check that the electrical supply delivers the voltage and frequency corresponding to the welding machine and that it is fitted with a delayed fuse suited to the maximum delivered rated current.
Note: The welding machines are set to the highest voltage at the factory.

Digital technology enables various machine settings to be applied with a high level of accuracy, giving the user precision control of every element of their welding.

SETTING THE WELDER

GENERAL
This medium weight, portable welder requires no special lifting instructions, however, it contains dedicated circuitry and must be handled with care. The welder is designed to weld with coated consumable electrodes (MMA), using a filler wire feed through the torch (MIG).

LOCATION

• Locate the machine close to the correct power supply and allow a 500mm air gap around to ensure sufficient ventilation. There are two cooling fans located in the rear of the machine housing which must be kept clear. Equally, ensure no debris can be drawn into the machine.
• Make certain the location does not pose any hazards as detailed in the safety instructions, before attempting to start the machine.
• Note: Refer to the rating label for energy input details.
• For TIG operations, ensure the gas bottle is securely mounted and in a vertical position according to the manufacturer’s instructions.
• Warning! Remove the plug from the socket before carrying out adjustment, servicing or maintenance.

MMA (MANUAL METAL ARC)

• To attach the electrode holder (13) to the front panel, insert the plug into positive coupling (10) and twist to lock.
• Attach the earth clamp (12) to the negative coupling (11) and twist clockwise to lock.

INSTALLING THE FILLER WIRE (MIG WELDER) – FIGS. 1 – 4

• The welding machine is designed to accept the standard size drums of wire (1kg).
• The welding wire can be either of the flux-cored types this provides a means of shielding the weld pool from the atmosphere.
• Or non-flux wire with the gas hose connected to the back of the machine.
• Do not let the filler wire become uncoiled or tangled as this will lead to problems with delivery to the welding torch.
• Select the filler wire suitable for the parent metal and with a gauge to match the welder specification.
• Note: If the welding machine is not regularly used, remove the wire which is prone to rust and will cause feed problems next time.

1. Open the side panel.
2. Unscrew the large plastic ring. Sit the reel on to the hub (17) and make sure the peg locates in the back of the reel. Refit the large plastic ring.
3. Fit the wire spool so that it feeds off the base of the reel towards the wire drive unit (18).
4. Pull tensioner (18.1) forward off the tension arm (18.2), the tension arm (18.2) will spring up out of the way.
5. The wire must sit in the appropriate groove for the wire gauge. The groove size is etched on the side of the roller. Remove nut to see the groove size that is NOT in use. The drive roller (18.4) can be removed from shaft, to change the groove size for appropriate wire gauge. Unscrew and remove the retaining cap.
6. Pass the filler wire through the guide (18.3) and over the top of the drive roller, make sure the wire is well inside the torch liner before closing the arm (18.2) and tensioner (18.1).
7. Connect the welding machine to the power supply.
8. Attach the earth as illustrated.
9. Press the feed trigger on gun and observe the wire feed mechanism. If the wire is being fed correctly it will come out of the swan neck. If it jams you will need to remove the gas shroud (9.1) and with a small spanner unscrew and remove the tip (9.2). Pass the tip over the wire and secure back onto the swan neck. Do not over tighten. Resecure the gas shroud and trim the wire back as required.
   Note: Ensure the tip size matches the wire size prior to installing.

NO GAS WELDING PRINCIPLE For a successful weld joint, the molten metal must be protected from contaminating gases found in the air. This is achieved by using a flux cored filler wire. The flux is produced as the wire melts.
The flux creates a coating over the weld and once cooled will need to be removed by chipping it off.
If allowed to cool naturally some areas of the flux may ping off of the weld by themselves due to thermal contraction for this reason it is recommended that eye protection is worn

BASIC WELDING OPERATION

Note: Although this machine is medium weight and portable take care with additional items i.e. gas bottles etc. Do not manoeuvre over people’s heads.

WELDING TYPE SELECTION – SWITCH – FIG.5

Note: Welding is a mix of science and art and due to the complex principles and vast differences in parameters (ie. Material type, position, condition etc.) That information is well beyond the scope of this manual. Draper Tools suggest training be obtained from a third party or refer to a suitable reference book on the subject additionally; nothing can beat practice using the welder on scrap material to get a better understanding.

SYNERGY MIG – FIG. 6
Requires just adjust welding current, other parameters like voltage, wire speed will automatically match.

For precise welding, adjust compensation voltage. Micro adjustment for desired welding voltage.
Position at middle is for standard welding.

MIG WELDING PRINCIPLES – FIGS. 7– 8

The MIG welding process allows two similar materials to be fused together without altering the properties of the material. The electric arc created between the electrode (the welding wire) and the work piece produces the required heat for turning the metal into a molten state. The gas creates a shield around the arc and the molten metal.
The area to be welded and the earth point must be clean of grease, dirt, paint and rust. Clean with a wire brush as necessary. Position the earth clamp as close as possible to the working area and ensure a tight grip is achieved.
Select the welding current based on the thickness of the material. A thick piece will require a high current, however due to the duty cycle this will effect the welding time by significantly reducing it. A thin piece will only require minimal heat and so the current can be less. This will allow a longer period of welding. The position of the torch is critical to the arc and end results.

The position of the welding torch is important to achieve a good quality bead. Position the torch at approximately 35° vertically and 75° horizontally and up to 20mm distance from the join. 20mm is the maximum that can be achieved on the maximum setting. Ensure the gas shroud remains clean of spatter. Likewise and more importantly the wire feed tip must be kept clean to avoid the wire becoming blocked or restricted.
Use of an anti-spatter spray (Draper Stock No.05709) will help keep the end result more tidy.

ARC WELDING, FILLER ROD (ELECTRODE) SELECTION – FIG. 9
The correct selection of electrode size and type will vary for each application dependent upon material thickness, material type, amperage and equipment, however as a guide the figures below provide an indication.

With the MMA welding process the arc created between the work piece and the consumable electrode rod melts the parent metal and the filler metal in a weld pool.
The electrode’s flux coating reacts during this process and develops into a shield gas protecting the weld bead. Part of this reaction leaves a trail of slag which solidifies behind the weld pool protecting the weld as it cools.
The most common varieties of electrodes are cellulosic, rutile and basic, the latter two being the most general purpose.
Selection of the appropriate specification electrode is important to achieve a good quality weld. Seek guidance if unsure of selection. MMA/ARC MACHINE OPERATION – FIG. 10
Prepare the joint(s) to be welded.
Select the electrode suitable for the application and insert into the electrode holder (13) while pressing lever (13.1).
With the earth clamp and electrode holder connected, connect the machine to the power supply. The power display will illuminate as confirmation. Set the amperage appropriate to the selected electrode size.
Secure the earth clamp to a clean sound section of the parent metal in the vicinity to the intended weld.
With all safety equipment in place and personal protective clothing on begin welding.
Lower the electrode down toward the parent metal and strike the arc.

DIRECTION OF WELD – FIG. 11
Strike the initial arc perpendicular to the parent metal before moving the electrode holder in the direction of travel 20-30° (Z,Y axis) and tilt it 20-30° (Z,X axis). Maintain a constant gap between the electrode tip and the weld pool of approximately 1 to 1.5 times the diameter of the electrode for a stable arc. This machine is equipped with two additional features ‘Arc Force’ and ‘Anti-Stick’ to ensure smooth welding and reduce the instances of the electrode becoming stuck to the parent metal.

Definition:
ARC FORCE

• The machine will automatically create a specific overpower when the electrode is too near, forcing it back to help avoid the risk of sticking.

Definition:
ANTI-STICK

• The machine will automatically reduce the intensity of the current in order to aid quick and simple separation of the electrode and parent metal.
• The position of the electrode is critical to the arc and the end result. Achieving a good weld will take practice.
• For more detailed information refer to a welding book and/or seek training on the subject.
• Use of an anti-spatter spray Draper stock No.05709 will help to achieve a cleaner finished weld. This welding power source has a maximum material thickness capability of 5mm.

THERMAL CUT-OUT
If welding for extended periods the thermal cut-out will activate prohibiting use of the machine until sufficiently cool.
Attention: After completion of any welding task leave the unit connected to the power supply for a sufficient period to allow the cooling fan to continue working.

DEFINITION:
DUTY CYCLE:
Duty Cycle is a percentage of 10 mins. in which a machine can operate at a rated load without overheating and interruption from the thermal cut-out device.
Example: 150A @ 30% Duty factor

150A welding for 3 minutes
7 minutes down time
Example: 95A @ 100% Duty factor
95A continuous welding
To increase the operation time, reduce the amperage.
Note: The heating tests have been carried out at ambient temperature and the duty cycle (duty factor) at 20°C has been determined by simulation
Definition:

ARC WELDING:
Fusion welding in which heat for welding is obtained from an electric arc.
Definition:

MANUAL METAL ARC (MMA welding):
Also known as SMAW (Shielded metal arc welding).
Metal-arc welding† with straight covered electrodes of a suitable length and applied by the operator without automatic or semi-automatic means of replacement. No protection in the form of gas from a separate source is applied to the arc or molten pool during welding.
†Arc welding using a consumable electrode.
Definition:

METAL INERT-GAS (MIG welding)
Also known as GMAW (Gas metal arc welding)
A welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt, and join. Along with the wire electrode, a shielding gas feeds through the welding gun, which shields the process from contaminants in the air.
