Assembling The Tig Torch
Ensure the Tig Torch is disconnected from the
welder before commencing assembly.
First make sure the insulator is seated properly
then screw the collet body into the torch body
(Fig.33), a very gentle nip with pliers will make
sure of a good electrical connection between
the collet body and the torch body, any arcing
here will wreck the torch.

Screw the ceramic cup onto the collet body. Do
not over tighten, just finger tight will be ideal.
Then slip the electrode through the collet,
Fig.34. Fit the electrode and collet from the rear
and screw on the back cap (Fig.35) and adjust

the tungsten stick out. gently tighten the back
cap just enough to grip the tungsten, over-
tightening will distort the collet. It is now ready
for welding.
