“Select welding parameters” button
This button is used to select the welding parameters depending on the welding process
and operating mode used.
2
sec
Gas pre-flow time (TIG), absolute setting range 0.0 sec to 20.0 sec (0.1s increments).
3
AMP%
Ignition current (TIG)
Percentage of the main current.
Setting range 1 % to 200 %
(1 % increments). There are no pulses
during the ignition current phase.
Hotstart current (MMA)
Percentage of the main current. Setting
range 1 % to 200 %
(1 % increments).
4
sec
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.
Hotstart time (MMA)
Setting ranges: 0.00 sec to 20.0 sec (0.1
sec increments).
Pulse time / slope time from AMP% to AMP / Spot time
• Pulse time setting range: 0.01 sec to 20.0 sec
(0.01s increments < 0.5 sec; 0.1 sec increments > 0.5 sec)
• Slope time (tS2) setting range: 0.0 sec to 20.0 sec
(see chapter "Advanced settings")
• Spot time setting range: 0.01 sec to 20.0 sec
5
sec
TIG pulses
The pulse time applies to the main current
phase (AMP) for pulses.
TIG AC Special
The pulse time applies to the AC phase for
AC special.
