Important! The maximum setting for the HOT-START current is limited by the maximum
circuit of the machine.

ARC FORCE CONTROL DIAL
Effect of arc force control dial (35) on constant-current characteristic at the moment of short
circuiting. Welding current setting 100 A
-
only effective in the electrode ignition phase
-
improved ignition even with electrodes where ignition is normally more difficult
-
improved melting of the base material in the ignition phase, meaning far fewer
cold laps
-
considerable reduction of slag inclusions
-
is added to the set welding current value on a percentage basis

use the remote control cable to create an electrical link bet-ween the connecting
socket [G] on the power source and the socket on the remote control unit.
insert the plug-in connections into the correct sockets and screw the coupling ring
on as far as possible.
