Electrode welding process
Connecting the electrode cable
 Connect the electrode cable to the minus 2 or plus 5 so-
cket and secure the cable by turning it to the right.
Heed the electrode manufacturer's instruc-
i
i
tions.
Connecting the ground cable
 Connect the ground cable to the free minus 2 or plus 5
socket and secure the cable by turning it to the right.
Fasten the ground clamp.
Fig. 12:
Fasten the ground clamp - Correct!
 Mount the ground clamp in the immediate vicinity of the
welding point such that the welding current cannot find
its own way via machine components, ball bearings or
electrical circuits.
 Connect the ground clamp firmly to the welding bench or
the workpiece.
Fig. 13:
Fasten the ground clamp - Incorrect!
Do not place the ground clamp on the welding machine or
the gas cylinder; otherwise the welding current will be car-
ried via the protective conductors and it will destroy these.

Connect the power supply
The machine is suitable for operation on the mains supply or
on a current generator.
 Plug the mains plug into the appropriate socket.
The mains voltage and tolerance as well as the
fuse protection must correspond to the techni-
cal specifications. (see Technical Data).
12.4
TIG welding process
Danger due to electric shock! If function HF-
ignition is selected, a high ignition voltage
is present at the
torch.
Never touch the welding electrode or parts
conducting welding current when the device
is switched on.
Connecting the torch
 Connect the torch to the socket 2 and secure it by turning
it to the right.
 Connect the torch's gas line to the gas connection 4.
 Plug the connector of the torch control cable into the
torch switch socket 3.
Only the control cable of a torch may be con-
nected to the torch switch socket 3.

Torch
 Unscrew the clamping cap 61.
 Remove the electrode 60 from the clamping sleeve 62.
 Grind the end of the electrode 60.
 Slide the electrode into 60 the collet 62.
 Insert the electrode 60 into the torch and screw the clam-
ping cap down 61 tight.
Do not disassemble the collet body 63 and the
i
i
gas nozzle 64.
