MAINTENANCE

Regular maintenance is important for safe, reliable operation.
Only personnel with the appropriate electrical skills (authorized staff) may remove
safety plates.
Supplier warranty is void if customer attempts any work on product during the
warranty period.
6.1

Power source

Check regularly that the welding power source is not clogged with dirt.
How often and which cleaning methods apply depend on:
S
the welding process
S
the arc times
S
the placement
S
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 will otherwise result in overheating.
6.2

Welding gun and torch

A regular programme of care and maintenance reduces unnecessary and expensive
downtime.
Each time a wire bobbin is changed, the welding gun should be removed from the
wire feeder and blown clean with compressed air.
The wire end must not have sharp edges when inserted into the wire liner.
For detailed information see instruction manuals for welding guns and torches.
