6 OPERATION
General safety regulations for the handling of the equipment can be found on
page 40. Read through before you start using the equipment!
WARNING – TIPPING RISK!
There is a risk of tipping while transportation and operation, if the welding machine leans
more than 10
o
. In that case appropriate securing has to be provided !

6.2 Function explanation
6.2.1 Overheating protection
A thermal overload cutout protects against overheating. The cutout resets automatically
when the unit has cooled.
6.2.2 Inductance connection
Higher inductance produces a more flowing weld and fewer spatters. Lower inductance
produces a harsher sound and a stable, concentrated arc.
