●
wire feed unit
●
welding gun
●
connection cable between power source and wire feed unit
●
gas bottle with suitable regulator

MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Only those persons who have appropriate electrical knowledge (authorized staff)
may remove the safety plates.
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:
●
welding process
●
arc time
●
placement
●
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.
6.2
Welding gun and clamp
Wear parts should be cleaned and replaced at regular intervals in order to achieve trouble-free
welding.
CAUTION!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any faults.
