Care and Maintenance
The unit is nearly maintenance-free.
B
Danger – Voltage!
Disconnect from power before servicing!
· Check feed roller, pressure roller and wire lead-
in nozzle at regular intervals for dirt build-up,
clean if necessary.
· At appropriate intervals the complete torch
including torch leads should be cleaned, as
rubbed-off parts and dust build-up inside.
· The torch's contact tip is a wearing part. If its ori-
fice has enlarged the contact tip must be
replaced.
· On the inside of the plug-on gas shroud spatters
build up. These have to be removed when nec-
essary. An anti-spatter spray eases this job and
keeps spatters from sticking to the shroud.
· Replace damaged cables without delay.
Trouble Shooting
Mechanical faults are mostly indicated by an irregu-
lar or completely blocked wire feed. Electrical faults
cause a malfunction of the unit, in part or complete.
B
Danger - Voltage!
Electrical fault finding must be left to a quali-
fied electrician.
Further fault finding can proceed according to the
wiring diagram supplied.
Fault find should first start with the unit de-ener-
gized, and in the following order:
1. Check of the power supply cable connection
and all other connections on switches, trans-
former and choke, as well as all plug-and-socket
connections and soldered connections for tight-
ness.
2. Check of fuse for continuity and contact.
3. Visual check for possible shorts or overloads of
windings (discoloring).
