Special 4-step
mode
"Special 4-step mode" is particularly suitab-
le for welding aluminium materials. The
special slope of the welding current curve
takes account of the high thermal conducti-
vity of aluminium.
Special 2-step
mode
"Special 2-step mode" is ideal for welding in
the higher power range. In special 2-step
mode, the arc starts at a low power, which
makes it easier to stabilise.
