9. Voltage/Amperage Control Switch
Control allows selection of either
panel or remote 14 for amperage or
voltage control.
10. Mode Switch
Switch determines both the process
and output On/Off control. Electrode
hot areas in gray are “contactor on”
positions.
Example: Preset for MIG process and steel wire
Control adjusts inductance for MIG welding.
Set Arc Control to desired wire type. Inductance
determines the “wetness” of the weld puddle.
As setting is increased (rotating Arc Control
clockwise), wetness (puddle fluidity) increases.
For best results, preset Arc Control to the wire
type. Then either increase or decrease setting
within wire type scale to make fine adjustment
to the welding arc.
Example: Stick Mode, 7018 Electrode
Control adjusts Dig when Stick mode is selected
on mode switch. Set Arc Control to desired
electrode type. For best results, preset Arc
Control in middle of the scale for appropriate
electrode type. Then either increase or decrease
setting within electrode type scale to make fine
adjustment to the welding arc.
