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 s to 20.0 s
(0.1 s increments).
The up-slope time can be set separately
for non-latched and latched.
Hotstart time (MMA)
Setting ranges: 0.00 s to 20.0 s
(0.1 s 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 chapter "Advanced settings")
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.
6
AMP
Main current (TIG) / pulse current
I min to I max (1 A increments)
Main current (MMA)
I min to I max (1 A increments)
7 sec
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 chapter "Advanced settings").
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.
