Operating manual
Pulsed 2T process:
T hotstart
Dstart
Soft-start
When the trigger is pulled, the pre-gas starts. When the wire touches the workpiece, a pulse initiates the arc. Then, the machine starts with HotStart
or upslope and finally, the welding cycle starts. When the trigger is released, the downslope initiates until it reaches crater fill. Then the STOP PEAK
cuts the wire followed by the Post gas. Just as in Standard mode, the user can quickly restart the welding process during the post-gas phase without
going through the HotStart phase.
Pulsed 4T process:
T hotstart
Dstart
4T
Soft-start
In pulsed 4T mode, the timing of the pre-gas and post-gas is managed automatically. HotStart and crater fill are controlled by the trigger.
TIG (GTAW) WELDING MODE
INSTALLATION AND GUIDANCE
• DC TIG welding requires a protective gas shield (Argon).
• Connect the earth clamp to the positive (+) plug connector. Plug in the TIG torch (ref. 046108) iinto the power source's EURO connector and the
reverse cable into the negative (-) connector.
• Ensure that the torch is properly fitted and that the consumables (vice grip pliers, collet bodies, diffusers and nozzles) are not worn out.
• The choice of electrode will depend on the current of the DC TIG process.
