FEED WIRE THROUGH TO TORCH
4.10.1.
Referring to fig.12 open the wire feed mechanism by pushing the locking/wire tension knob (1) down to the right allowing the pressure
roller carrier (2) to spring up revealing the feed roller. Ensure that the required feed groove (0.6 or 0.8) is in line with the wire path. See
Section 3.12 on how to reverse or change the roller.
4.10.2.
Release the wire from the reel and cut off any bent portion ensuring that there are no burrs left on the end of the wire. Keep the wire under
tension at all times to prevent it uncoiling.
4.10.3.
Straighten about 40-50mm of wire and gently push it through the flexible metal sheathed cable (3) and through the 6 or 8mm feed roller
groove and on into the torch cable liner.
4.10.4.
Push down the pressure roller carrier onto the wire feed roller and hold it down. Lift up the locking/wire tension knob so that it enters the slot
in the pressure roller carrier and snaps into the indent in its top surface. See fig.13. Rotate the tension knob to a medium setting i.e. between
2 and 3.

emove gas cup (fig.11-2) and contact tip (1) from end of torch as follows:
a) Take torch in left hand with the torch tip facing to the right.
b) Grasp gas cup firmly in your right hand.
c) Turn gas cup clockwise only and pull it off end of torch tip.
WARNING! do not turn gas cup anti-clockwise, as this will damage the internal spring.

d) Unscrew copper contact tip (right hand thread) to remove.

set the voltage switch to one.
4.10.7.
Set the wire speed knob to position 5 or 6. Keep the torch cable as straight as possible and press the torch switch. The wire will feed
through the torch.
4.10.8.
When the wire has fed through, switch welder off, unplug from mains.
a) Take torch in left hand, slide the contact tip over the wire and screw back into place.
b) Grasp gas cup in right hand, push onto torch head and turn clockwise only. Do not turn gas cup anti-clockwise, as this will damage the
internal spring.
c) Cut wire so that it is just protruding from the cup.
4.11.
SETTING WIRE TENSION
4.11.1.
Adjust the wire tension by rotating the wire tension knob. Turn clockwise to increase the tension and anticlockwise to decrease the
tension. See (1) in fig13.
IMPORTANT: Too little or too much tension will cause problematic wire feed and result in poor welding.
4.11.2.
Tension between rollers is checked by slowing down the wire between gloved fingers. If top feed roller skids the tension is correct. Use
as low a tension as possible, too high a tension will disfigure wire and result in a blown fuse.

CLUTCH ADJUSTMENT
Note: It is essential that the clutch is adjusted correctly.

Note: DO NOT over tighten the clutch as this will cause wire feed problems and strain the motor.

T T URNING/CHANGING THE DRIVE ROLLER
URNING/CHANGING THE DRIVE ROLLER (See fig.14)
4.13.1.
Ensure that the wire diameter used, is matched by the correct groove size in the drive wheel and the correct tip size on the torch as well
as the correct torch liner. Failure to do this could cause the wire to slip and/or bind.
4.13.2.
Referring to fig.12, open the wire feed mechanism by pushing the locking/wire tension knob (1) down to the right allowing the pressure
roller carrier (2) to spring up revealing the feed roller.
4.13.3.
Referring to fig.14, loosen and unscrew the black feed roller retaining knob (C) and put to one side.
4.13.4.
The roller carrier (A) is keyed to the main drive shaft and the drive roller (B) is keyed to the carrier, see below. Place a finger onto the
end of the drive shaft to prevent the carrier moving and slide the drive roller off the carrier with your other hand.
4.13.5.
The size of each wire feed groove is printed on the edge of the roller on the same side as the groove.
4.13.6.
Turn the roller over to use the other groove or use a roller with different sized grooves as required. The groove to be used should be
positioned furthest away from you to be in line with the drive path.
