Feeding the wire through to the torch.
(fig.5) Remove gas cup (a) and contact tip (b) 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 cup out to the right.
WARNING!
do not turn gas cup anti-clockwise, as this will damage internal spring.
d) Unscrew the copper contact tip (right hand thread) to remove.
3.1.9. Check welder is switched OFF and that the earth clamp is away from the torch tip. Connect the welder to the mains power supply and set
the voltage switch to MIN.
3.1.10. 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.
3.1.11. When 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 it back into place.
b) Grasp gas cup in right hand, push onto torch head and turn clockwise only.
WARNING!
do not turn gas cup anti-clockwise, as this will damage internal spring.
c) Cut wire so that it is just protruding from the cup.
3.2.
Setting wire tension.
IMPORTANT:
Set the correct tension, too little or too much tension will cause wire feed problems and result in a poor weld.
3.2.1. Correct tension between the rollers is checked by slowing down the wire between gloved fingers. If the pressure roller skids the tension is
correct. Try to use the lowest tension possible as too high a tension will deform the wire. When welding has been completed allow the
welder to cool before storing in a safe, dry place.
Note:
Damaged torches and cables are not covered under warranty.
