Status displays
After each completed welding task, the last values used in the welding
process for the welding current and welding voltage are shown on the
displays, and the signal light will be on

Select welding parameters button
This button is used to select the welding parameters depending on the welding process
and operating mode used.

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).

AMP
Main current (TIG) / pulse current
I min to I max (1 A increments)
Main current (MMA)

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 5.9.13 Pulse variants chapter
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.
