4.09 Spot Welding Operation
Fit an optional spot welding nozzle to the MIG gun for consistent spot welding operations. Refer to Figure 4-18
and the Spot Welding Nozzle table below. The Fabricator 210 will operate effectively using .030” (0.8mm) electrode
wire when spot welding. Penetration depth is limited when using .024”(0.6mm) electrode wire for spot welding.
Set the controls as follows for spot welding:
Coarse & Fine Voltage Selector Switches and Wirespeed Control
Select higher Voltage Selector switch positions and set the Wirespeed Control between 354 to 590 ipm (9 to 15 m/
min) for maximum penetration.
Mode Selector Switch
Set the WELD MODE switch to SPOT.
Spot Time
Adjust the WELD (Spot/Stitch) control knob for the desired weld or ‘ON’ time for spot welding.
Dwell Time
The DWELL (Stitch) control knob has no affect in this mode of operation.
