6.5.1

Dirt filter

These accessory components can be retrofitted as an option, see Accessories chapter.
The dirt filter can be used in places with unusually high levels of dirt and dust in the ambient air.
The filter reduces the duty cycle of the welding machine via the reduced flow of cooling air. The
filter must be disassembled and cleaned regularly depending on the level of dirt (blow out with
compressed air).
• As shown in the diagram, insert the dirt filter into the rear of the machine, above the air inlet, using
both clips (1).
• Fold down the dirt filter (2).
• Fasten the dirt filter to the underside of the machine (3) using fixing screws.
6.6 Workpiece lead, general
Remove paint, rust and dirt from clamping and welding areas with a wire brush. The workpiece
clamp must be mounted near the welding point and must be fixed in such a way that it cannot
come loose of its own accord.
Structural parts, pipes, rails etc. may not be used as return leads for the welding current unless
they are part of the actual workpiece.
Correct current connection must be ensured when using welding benches and appliances.
