G Welding current knob. Continuous adjustment of the welding current between 20 A and 450 A.
H
Main switch Position “0”: machine off. Position “I”: machine on. The mains indicator light illuminates. The fan
is running.
I
Temperature fault light. Illuminates if the welding transformer or thyristor set overheats. The arc can no longer be
started. If the fan is running, the machine will ready for operation again after approximately 5 minutes.
