TIG latched operation
•
Adjust the appropriate changeover switches to the following settings:
TIG
MMA
HF
When the
foot-operated remote control
RTF is connected, the machine switches
automatically to non-latched operation. The Up- and Down-slopes are switched off.

Step 1
•
Press torch trigger 1, the gas pre-flow time passes.
•
HF ignition pulses jump from the electrode to the workpiece, the arc ignites.
•
Welding current flows and immediately assumes the ignition current value set (search arc at
minimum setting). HF is switched off.
Step 2
•
Release torch trigger 1.
•
The welding current increases in the adjusted Up-slope time to the main current AMP.
(Secondary current AMP% see Chap. 3.1)
Changeover from the main current AMP to the secondary current AMP%:
•
Press torch trigger 2 or
•
Tap torch trigger 1 (tapping mode see also Chap. 3.2.4)
Step 3
•
Press torch trigger 1.
•
The main current falls in the adjusted Down-slope time to the end-crater current I
end
(minimum
current).
4
th
step
•
Release torch trigger 1, the arc extinguishes.
•
The gas post-flow time set begins.
Immediate termination of the welding procedure without Down-slope and end-crater
current:
•
Briefly press the 1st torch trigger (3rd and 4th step).
The current falls to zero and the gas post-flow time begins.
