MOUNTING THE WELDING WIRE SPOOL
WARNING: Ensure that the welder is not connected to the mains supply.
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 over the spindle so that it sits against 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.
8. There are different drive rollers for aluminium and flux cored wires
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 tensioning knob and pivot it towards you.
3. Lift up the arm.
