MOUNTING THE WELDING WIRE SPOOL

WARNING: Ensure that the welder is not connected to the mains supply.
NOTE: Spools of welding wire are available from your dealer.
1. Open the side panel, by pushing the latch down and allowing the side panel to drop down.
2. Remove the locking knob and retaining disc.
3. Place the spool of welding wire (not supplied) over the spindle so that it sits on the spring.
· Do not release the tension on the wire as it will unravel causing feeding problems later.
· The wire will feed off the spool anticlockwise from the bottom of the reel.
· The spool must be fitted with the correct orientation otherwise it will not feed correctly.
SETTING THE DRIVE ROLLER SIZE
1. Loosen the tensioning knob and pivot it towards you
2. Lift up the arm.
3. Take hold of the triangular knob on the drive roller cover and rotate it 90°anticlockwise to release it.
4. Pull the roller retainer off the drive spindle to reveal the roller.
5. Pull the roller off the drive spindle.
· The groove size is stamped on the corresponding side of the roller. Select the groove size according to
the size of the wire you are using and put the roller back on the spindle with your chosen side facing
you.
6. Replace the drive roller cover back onto the drive spindle with the opening facing right.
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 burrs and then
straighten the next 15 cm of wire to help with feeding.
2. Loosen the tension knob and pivot it towards you.
3. Lift up the arm.
4. Pass 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 replace the tensioning knob.
· Tighten the tensioning knob sufficiently to hold firmly, 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 (0.8 mm is supplied fitted*) to suit your wire. the replace the
shroud.
· A spare 1.0 mm tip is supplied loose and should be used when using 0.9 mm flux cored wire the contact
tip and shroud.*
12. Trim the welding wire so that it protrudes no more than 5 mm from the end of the contact tip.
*Not included with all models.
