Welding machine cooling system
Observe the following to attain the optimum duty cycle of the power components:
•
Ensure that the working area is adequately ventilated,
•
Do not obstruct the machine’s air inlets and outlets,
•
Metal parts, dust or other foreign bodies must not get into the machine.
5.4
Workpiece lead
Remove paint, rust and dirt from clamping and welding areas with a wire brush! Attach the
workpiece clamp in the immediate vicinity of the welding position! Structural parts, pipes,
rails etc. may not be used as return leads for the welding current if they are not the
workpiece themselves!
A perfect current connection must be ensured where welding benches and appliances are
concerned.
•
Insert cable plug of the workpiece lead into the welding current socket (Chap.2, B
)
and lock by
turning to the right.
MMA welding:
The polarity depends on the instructions of the electrode manufacturer on the electrode
packaging.
5.5
Electrode holder connection (MMA welding)
•
Insert cable plug of the stick electrode holder into the welding current socket "+" (Chap. 2, B
)
or
"-" (Chap. 2, C"
)
and lock by turning to the right.
The polarity depends on the instructions of the electrode manufacturer on the packaging.
