Spot and stitch welding
General The spot and stitch welding modes are MIG/MAG welding processes. The spot
and stitch welding modes can be activated on the power source control panel.
Spot welding is used on welded joints on overlapped sheets that are only access-
ible on one side.
Stitch welding is used for light-gauge sheets.
As the wire electrode is not fed continuously, the weld pool can cool down during
the intervals. Local overheating leading to the base material being melted
through is largely avoided.
Spot welding Activating spot welding mode:
-
For the SPt Setup parameter (spot / stitch welding time), enter a value >
OFF
As soon as a value is entered for the SPt Setup parameter, spot welding mode is
activated. The spot / stitch welding indicator (SF) lights up on the control panel.
Preparations:
1
Set the spot / stitch welding time (SPt) in the Setup menu
2
Select the filler metal, wire diameter and shielding gas being used with the
relevant buttons
3
Select the desired welding process:
MIG/MAG standard manual welding
MIG/MAG standard synergic welding
4
Select the desired MIG/MAG mode:
2-step mode
(For spot welding mode, only 2-step mode is available)
5
Depending on the selected welding process, select the desired welding para-
meters using the relevant adjusting dial
6
Open the gas cylinder valve
7
Set the shielding gas flow rate
WARNING!
Danger due to emerging wire electrode.
This can result in serious personal injuries.
▶
Hold the welding torch so that the tip of the welding torch points away from
the face and body.
▶
Wear suitable protective goggles.
▶
Do not point the welding torch at people.
▶
Ensure that the wire electrode does not touch any electrically conductive ob-
jects.
