Non-Latched Operation, Version C - EWM Tetrix 451 AC/DC AW FW Operating Instructions Manual

5.7.10.6 Non-latched operation, version C

1st cycle
•
Press torch trigger 1
•
HF ignition pulses jump from the electrode to the workpiece. The arc ignites.
•
Welding current flows and immediately assumes the set ignition current
setting). HF switches off.
2nd cycle
•
Release torch trigger 1.
•
The welding current ramps up to the main current AMP in the selected up-slope time
Pressing torch trigger 1 starts the slope
Releasing the torch trigger starts the slope
current AMP. This process can be repeated as frequently as required.
The welding process is stopped by interrupting the arc in the secondary current (remove the welding torch
from the workpiece until the arc is extinguished, no re-ignition).
