TACK WELDING ( Manual or
• SPOT
This welding mode allows the parts to be pre-assembled before welding. Spot welding can be done manually using the trigger or timed at a predefi-
ned pace. This spot welding timer is useful for better reproducibility and when making non-oxidized welds (accessible in the advanced menu).
