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 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)
•
Slope time (tS2) setting range: 0.0 s to 20.0 s > see 5.7.11 chapter
TIG pulses
The pulse time applies to the main current
phase (AMP) for pulses.
Secondary current / pulse pause current
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 5.7.11 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.
Down-slope time (TIG)
End-crater current signal light
Signal light, gas post-flow time
Balance signal light
AC balance (TIG)/pulse balance (TIG DC – kHz pulses)/pulse balance (MMA)
Frequency signal light
AC frequency (TIG)/pulse frequency (TIG DC – kHz pulses)/pulse frequency (MMA)
Machine control – Operating elements
