8.3. Operation:
8.3.1. After installation, breaker on back panel is turned on to activate the welder. Panel first displays version
number of the machine and then current setting value which varies between minimum and maximum
by adjusting welding current knob.
8.3.2. Based on using habits and actual condition, hot start, arc-force setting hot start and arc-force current
are adjusted in secondary menu. Ammeter displays current value of hot start and arc force. When hot
start current and arc-force current are set without adjusting the knob, ammeter displays welding current
setting value after 3S.
8.3.3. Electrode is clamped by electrode holder to weld with short-circuit striking arc. Please refer to 8.4 for
welding parameters. Ammeter displays actual welding current value during the welding.
