Select welding parameters button
This button is used to select the welding parameters depending on the welding process
and operating mode used.
Gas pre-flow time signal light
Signal light
Ignition current (TIG)/hot start current
Signal light
Up-slope time (TIG)/hot start time
Main current (TIG) / pulse current
I min to I max (1 A increments)
Pulse break time/slope time from AMP to AMP%
•
Pulse break setting range: 0.01 sec to 20.0 sec
(0.01 sec increments < 0.5 sec; 0.1 sec increments > 0.5 sec)
•
Slope time (tS1) setting range: 0.0 sec to 20.0 sec > see 5.3.13 chapter
TIG pulses: The pulse break time applies to the secondary current phase (AMP%)
TIG AC Special: The pulse break time applies to the DC phase with AC special.
Secondary current / pulse pause current
Pulse time / slope time from AMP% to AMP
•
Pulse time setting range: 0.01 s to 20.0 s
(0.01 s increments < 0.5 s; 0.1 s increments > 0.5 s)
