6.3.1
Dirt filter
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).

Cooling air inlet
• Fix dirt filter with 4 fixing screws on the front of the casing (cooling air inlet) of the welding machine.

Mains connection
The operating voltage shown on the rating plate must match the mains voltage.
For mains fuse protection, please refer to the “Technical Data” chapter.
The correct mains plug must be attached to the mains supply lead on the machine.
The connection must be made by a qualified electrician in compliance with the relevant local laws
and regulations.
The phase sequence for three-phase machines is optional and has no effect on the fans direction
of rotation.
• Insert mains plug of the switched-off machine into the appropriate socket.
6.5
Machine cooling
To obtain an optimal duty cycle from the power components, the following precautions should be
observed:
•
Ensure that the working area is adequately ventilated,
•
Do not obstruct the air inlets and outlets of the machine,
•
Do not allow metal parts, dust or other objects to get into the machine.
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.
