Electrode welding process

Connecting the electrode cable
Connect the electrode cable to the minus 8 or plus 7
socket and secure the cable by turning it to the right.
Note the manufacturer information when
i
you select a suitable stick electrode. The
electrode diameter depends on the thick-
ness of the material to be welded.
Welding with positive (+) electrode:
 connect the electrode holder to the positive pole con-
Ânector 7 and lock it by turning the plug clockwise.
Welding with negative (–) electrode:
 connect the electrode holder to the negative pole
con- Ânector 8 and lock it by turning the plug clock-
wise.
 Press the handle at the grip of the electrode holder.
ÂClamp the electrode with its blank end in the holder.
Consider when doing the notch at the inner side of
both blocks.

 Unscrew the clamping cap 55.
 Push the tungsten electrode 54 through the suitable
clamping sleeve 53.
 Point the tungsten electrode 54 by grinding.
 Push the tungsten electrode 54 through the suitable
clamping sleeve 53.
 insert the sleeve and rescrew the clamping cap 55.
Do not dismount the clamping sleeve cas-

‰ The collet 53, collet body 51 and electrode 54 mus-
thave the same diameter.
‰ The gas nozzle 50 must be matched to the electrode
diameter.

Abb. 6: Connecting the inert gas cylinder
 Secure the shielding gas cylinder 60,e.g. by using a
securing chain.
 Briefly open the gas cylinder valve 61 several times
in order to blow out any dirt particles present.
 Connect the pressure reducer 64 to the shielding gas
cylinder 60.
 Screw the shielding gas hose 65 onto the pressure
reducer 64 and open the shielding gas cylinder 61.
 Handy 180: Press the torch key Start/Stop 70.
 Handy 160 ControlPro: Open the gasvalve at the
TIG-valve torch.
