Care, maintenance and disposal
General Under normal operating conditions, the power source requires only a minimum of
care and maintenance. However, it is vital to observe some important points to
ensure the welding system remains in a usable condition for many years.
Safety
WARNING!
Danger from electrical current.
This can result in serious personal injury and damage to property.
▶
Before starting work, switch off all devices and components involved, and
disconnect them from the grid.
▶
Secure all devices and components involved so they cannot be switched back
on.
▶
After opening the device, use a suitable measuring instrument to check that
electrically charged components (such as capacitors) have been discharged.
At every start-
up
-
Check mains plug, mains cable, welding torch, interconnecting hosepack and
grounding (earthing) connection for damage
-
Check whether the all-round clearance of 0.5 m (1 ft. 8 in.) is kept to ensure
that the cooling air can easily flow and escape.
NOTE!
Air inlets and outlets must never be covered, not even partially.
If necessary If a lot of dust has accumulated:
-
Remove the fin element on the rear of the housing
-
Detach the air filter located behind and clean
Every 2 months
-
If present: clean air filter
Every 6 months
CAUTION!
Danger due to the effect of compressed air.
This can result in damage to property.
▶
Do not clean electronic components with compressed air from a short dis-
tance.
-
Open the device
-
Blow out the inside of the device with dry and reduced compressed air
-
Also clean the cooling air ducts if there is a large accumulation of dust
