6.1 Inspection and cleaning
Power source
Check regularly that the welding power source is not clogged with dirt.
How often and which cleaning methods apply depend on: the welding process, arc
times, placement, and the surrounding environment. It is normally sufficient to blow
down the power source with dry compressed air (reduced pressure) once a year.
Clogged or blocked air inlets and outlets otherwise result in overheating.
TIG torch
The TIG torch's wear parts should be cleaned and replaced at regular intervals in
order to achieve trouble-free welding.
7 FAULT-TRACING
Try these recommended checks and inspections before sending for an authorized
service technician.
Type of fault Corrective action
No arc. Check that the mains power supply switch is
turned on.
Check that the welding current supply and return
cables are correctly connected.
Check that the correct current value is set.
Check to see whether the MCB has tripped.
The welding current is
interrupted during welding.
Check whether the thermal cut-outs have tripped
(indicated by the orange lamp on the front panel).
Check the mains power supply fuses.
The thermal cut-out trips
frequently.
Check to see whether the dust filter is clogged.
Make sure that you are not exceeding the rated
data for the power source (i.e. that the unit is not
being overloaded).
Poor welding performance. Check that the welding current supply and return
cables are correctly connected.
Check that the correct current value is set.
Check that the correct electrodes are being used.
Check the gas flow.
