ELECTRICAL INSTALLATION

WARNING!
Highly dangerous – risk of electric shock
EARTHING AND RADIO INTERFERENCE PROTECTION
The product must be connected to earth.
The product generates, uses and can emit radio-frequency energy, and if not installed and used according to the instructions can cause interference to radio, television and  other electronic equipment. Correct earthing can limit or eliminate such problems.
Disruptive, radio-frequency energy can be emitted in several different ways.

• Direct radiation from source of welding current.
• Direct radiation from welding cables.
• Direct radiation as a result of mains interaction.
• Indirect radiation from non-earthed metal objects.

Follow the instructions below to counteract such interference.

1. Keep the leads between the mains outlet and product as short as possible and if possible provide the leads with metal shielding connected to earth.
2. Keep the welding cables (electrode cable and return cable) as short as possible. Fasten if possible the welding cables together to form a pair with insulating tape or the equivalent.
3. Check that the insulation on the electrode and non-return cables is free from nicks, cracks and other damage that can cause leakage current.
4. Keep the return cable and its connections in good condition – clean the surface of the work bench where the return cable clips are connected at regular intervals.

CONNECTION OF MAINS VOLTAGE

• Check that the mains voltage corresponds to the rated voltage on the type plate.
• Allow an authorised electrician to install an earthed power point if the plug does not fit in the power point.
• Switch off the product with the power switch and pull out the plug before working on the product.
• Do not attempt to repair the product yourself. Take it to an authorised electrician or service centre.
• Wait 5 minutes after switching off and unplugging the product so that the capacitors have time to discharge before carrying out service or any other work on the product. Never touch live parts.
• The product is supplied with 1-phase 230 V 50/60 Hz.

USE

CONFIGURATION FOR MMA

1. Switch on the power source and set the MMA/MIG/TIG selector in MMA mode.
2. Set the correct welding current for the welding electrode to be used, as per the table below.
   Electrode diameter (mm)| Setting
   ---|---
   1.0| 1
   2
   3
   2.5| 4
   5
   6
   3.2| 7
   8
   4.0| 9
   10

3. Connect the welding cables. The welding current source has two welding cable connections. For manual arc welding (MMA) the electrode holder should normally be connected to the positive connection and the workpiece, via the return cable, to the negative. Sometimes, however, the polarity can be the reverse – check and follow the instructions of the electrode manufacturer.

CONFIGURATION FOR MIG

1. Switch on the power source and set the MMA/MIG/TIG selector in MIG mode.
2. Put the MIG torch cable in the outlet connection on the front panel and tighten the connection.
3. Put the return cable in the negative connection on the front panel and tighten the connection clockwise.
4. Put the quick-coupling for the wire guide in the wire feed outlet on the front panel and tighten the quick-coupling clockwise.
5. Remove the product casing and put the wire spool on the wire spool spindle. Release the end of the wire and cut it straight across. Release the pressure arm, align the wire in the slot on the drive roller and insert the end of the wire in the wire guide inlet on the torch hose. Check that the drive roller and MIG torch connector nozzle suits the diameter of the wire. Otherwise replace with the correct drive roller and connector nozzle. Lock the pressure arm and check that the pressure roller holds the wire correctly pressed in the slot.
6. Press the selector for wire inching and hold it pressed in until the wire sticks out from the MIG torch.
7. Connect the supplied brass nipple for the gas regulator to the gas hose on the back of the welding current source and set the regulator to the required flow of shielding gas.
8. Set the welding current and wire feed according to the type of joint and thickness etc.
9. Move the torch up to the starting point, press the trigger and start welding.

CONFIGURATION FOR TIG

1. Switch on the power source and set the MMA/MIG/TIG selector in TIG mode.
2. Set the correct welding current for the welding electrode to be used, as per the table below.
3. Connect the welding cables. The welding current source has two welding cable connections. For TIG welding the TIG torch should normally be connected to the negative connection and the workpiece, via the return cable, to the positive.

Tip for welding with hollow wire (without shielding gas)

• When welding with hollow wire the polarity of the arc may need to be reversed. This is easily done by reversing the wires in the wire feeder.
• Solid wire (with shielding gas): positive torch, negative workpiece (standard setting)
• Hollow wire (without shielding gas): negative torch, positive workpiece.

MAINTENANCE

WARNING!

•  Switch off the product with the power switch and pull out the plug before working on the product.
• Do not attempt to repair the product yourself. Take it to an authorised electrician or service centre.
• Wait 5 minutes after switching off and unplugging the product so that the capacitors have time to discharge before carrying out service or any other work on the product.
• Never touch live parts.
• At intervals of 3 to 6 months, depending on frequency of use and working conditions, the side and top panels should be removed and the inside of the product blown clean with dry compressed air at low pressure. Circuit boards and electrical components and cooling fans should be blown clean very carefully.
