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 (TIG), absolute setting range 0.0 sec to 20.0 sec (0.1s increments).
Ignition current (TIG)
Percentage of the main current.
Setting range 1 % to 200 %
(1 % increments). There are no pulses during the ignition current phase.
Up-slope time (TIG)
Setting ranges: 0.00 sec to 20.0 sec (0.1 sec increments).
The up-slope time can be set separately for non-latched and latched.
Main current (TIG)/pulse current
Value is specified by a control voltage.
Pulse time/slope time from AMP% to AMP
Value is specified by a control voltage and shown on the display.
Secondary current (TIG)
Value is specified by a control voltage and shown on the display.
Pulse pause time/slope time from AMP to AMP%
Value is specified by a control voltage and shown on the display.
Down-slope time (TIG)
0.00 sec to 20.0 sec (0.1 sec increments).
The down-slope time can be set separately for non-latched and latched.
End-crater current (TIG)
Setting range 1 % to 200 % (1 % increments). Percentage of the main current.
Gas post-flow time (TIG)
Setting ranges: 0.00 sec to 40.0 sec (0.1 sec increments).
Balance TIG DC pulses (kHz)
No function in current configuration
Frequency TIG DC pulses (kHz)
No function in current configuration.
activArc TIG welding process
• Switch activArc on or off
• Correct the activArc characteristic (setting range: 0 to 100)
