Operating mode switch
For more information on these modes, see Set the operating mode switch on page 47.
Amperage adjustment knob
Status screen
The operating mode switch can be set in one of four positions:
 Continuous pilot arc. Cuts expanded metal or grate.
 Non-continuous pilot arc. Cuts or pierces metal plate. This is the standard
setting for normal drag-cutting.
 Gouge. Gouges metal plate.
 Torch lock. Same as the non-continuous pilot arc mode except the torch is
locked in the ON position when you release the trigger during a cut. The torch
goes out when the transfer is lost or the torch is retriggered.
This knob adjusts the amperage. When operating in manual mode, you can also use this knob
to adjust the gas pressure, overriding the automatic setting for optimized applications.
