7. Ensure that the flanges at the base of the drive roller cover, seat fully into the

circular recess in the main moulding and then rotate the drive roller cover through

90° to lock it in place.

THREADING THE WIRE

IMPORTANT: Do not release the tension on the wire as it will unravel

causing feeding problems later.

1. Pull out the end of the wire from the spool, taking care not to release the tension.

• We recommend you cut off and discard the first 10 cm of wire from the

spool to avoid any burrs and then straighten the next few centimetres of

wire to help with feeding.

2. Loosen the tensioning knob and pivot it towards you.

3. Lift up the arm.

4. Feed the wire through the guide,

over the drive roller and into the

torch liner.

• Push about 10-15 cm into the

torch liner.

5. Lower the arm and refit the

tensioning knob.

• Tighten the tensioning knob

sufficiently to hold in position, but

do not fully tighten.

NOTE: Correct tension will allow the wire to feed into the torch liner smoothly

but will allow the drive roller to slip in the event of a blockage.

6. Close the side panel of the welder.

7. Pull off the torch shroud with a twisting movement, then unscrew the contact tip.

8. Connect the welder to the power supply and switch ON.

9. Set the ‘WIRE FEED’ rotary control on the front panel to position 7 or 8 and

squeeze the trigger on the torch body.

• The wire will feed through the hose until it appears at the torch tip.

• Ensuring the hose is free from kinks during this process will assist the wire

in its passage through the hose liner.

10. Release the trigger and switch off the welder and disconnect the machine from

the mains supply.

11. Refit the appropriate size contact tip (the 0.9 mm tip, for no gas welding is

supplied fitted) to suit your wire and replace the shroud.
