Amperage Control:
Controls the welding amperage output. Limits the
maximum output of a remote amperage device.
[PPS]* Pulse Control:
Reduces heat input to minimize distortion and increase
travel speed. Set PPS (pulses per second). The range
is OFF−250 PPS. The Background Amperage and Peak
Amperage are not adjustable. Background Amperage
equals 25% of Peak amperage. Peak amperage Time
equals 40%.
[POST] Post Flow Control:
Controls the length of time gas flows after welding
stops. Range is AUTO, OFF−50T (seconds). AUTO
calculates the time based on the maximum amperage
of each weld cycle. The minimum time is 8 seconds.
Auto equals maximum amperage/10.
*PRO−SET provides PROfessionally developed
SETtings for the weld process. To use PRO−SET,
press the menu button to display the parameter and
adjust the encoder until PRO−SET flashes on the dis-
play. PRO−SET flashes one time and reveals the pro-
fessional setting for the parameter.
