Seam Welding
IMPORTANT: Seam spot welding does not have the
strength of a MIG weld and should never be used for
structural welding. Due to its low emission of heat; how-
ever, seam spot welding is very useful for patching holes
on panels.
1. Fit proper electrode in the pistol. (See unit components
- page 2.)
2. Clamp ground shoe to bottom piece of steel prior to
welding top piece of steel to bottom piece of steel.
NOTE: When applying a pistol weld to top piece of
steel, the ground shoe must be clamped to the
bottom piece of steel to allow a flow of current
through the two parts.
3. Select program and thickness of sheets to be welded.
If thicknesses are different, only consider the thinner
piece of steel.
NOTE: The power and welding time are preset and
parameters will automatically appear on the display.
If the preset parameters have been changed set
power and time according to the chart at right or
reset the timer as indicated on page 4 to recover the
original factory settings.
4. Position the electrode at the desired location. Apply
moderate pressure and pull the trigger. Hold trigger for
approximately three pulses.Then gradually tilt the pistol
to the front to begin rolling the electrode. The advance
speed is approximately 1 inch per 4 seconds. Control
the advance speed by checking the heat.
NOTE: The seam welding process allows operator to weld
zinc coated steel and high strength steel with the same
program used for welding of mild steel.
