Spot and Stitch Welding
General The spot welding and stitch welding modes are MIG/MAG welding processes. The spot
welding and stitch welding modes are activated on the control panel.
Spot welding is used on welded joints on overlapping sheets that are only accessible on
one side.
Stitch welding is used for light-gage sheets.
As the wire electrode is not fed continuously, the weld pool can cool down during the
intervals. Local overheating leading to the parent material being melted through is largely
avoided.
Spot welding
1
In the Setup menu, set the spot welding time / stitch welding time SPt
IMPORTANT! Stitch pause time SPb = OFF must be set for spot welding!
2
Only for synergic welding:
Use the corresponding buttons to select the filler metal used, the wire diameter, and
the shielding gas
3
Select the desired welding process:
MIG/MAG standard manual welding
MIG/MAG standard synergic welding
MIG/MAG pulsed synergic welding
4
Select spot welding/stitch welding mode:
Spot welding/stitch welding
The spot/stitch/SynchroPulse (SF) indicator lights up on the control panel.
5
Depending on the welding process selected, select the desired welding parameters
and adjust them using the appropriate selection dial
