Non-Latched Automatic - EWM TIGSPEED OSCILLATION DRIVE 45 COLDWIRE Operating Instructions Manual

5.2.3.4

Non-latched automatic

The welding machine has to be set to a non latched operating mode.
First cycle (current)
•
Press torch trigger 1 (BRT 1) and keep pressed.
•
The gas pre-flow time elapses.
•
HF ignition pulses jump from the electrode to the workpiece. The arc ignites.
•
The welding current flows and immediately assumes the value of the starting current I
•
HF switches off.
•
The welding current increases in the set up-slope time to the main current AMP.
•
The wire electrode is fed once the delay time (t-start) has elapsed.
Second cycle (current)
•
Release BRT 1.
•
Wire electrode feeding is stopped, wire electrode is returned by the set wire return value.
•
The main current is reduced in the selected down-slope time, the arc is extinguished.
•
Shielding gas continues to flow in the selected gas post-flow time.
