Selection
• Select latched special mode
.
Step 1
• Press and hold torch trigger.
• Shielding gas is expelled (gas pre-flows).
The arc is ignited using liftarc.
• Welding gas flows at pre-selected setting in start program "P
START
".
Step 2
• Release torch trigger.
• Slope on main program "P
A
".
The slope on main program P
A
is given at the earliest after the set time t
START
elapses and at the
latest when the torch trigger is released.
Tapping can be used to switch to the reduced main program "P
B
". Repeated tapping will switch
back to the main program "P
A
".
Step 3
• Press the torch trigger.
• Slope to end program "P
END
".
Step 4
• Release torch trigger.
• Arc is extinguished.
• Gas post-flow time elapses.
5.4.4.2 TIG automatic cut-out
The welding machine ends the ignition process or the welding process with an
• ignition fault (no welding current flows within 5 s after the start signal)
• arc interruption (arc is intrerrupted for longer than 5 s)
