USERS MANUAL
Welding On One Side (Pistol)
1. Fit welding electrode to 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 bot-
tom 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 origi -
nal factory settings.
4. Position the electrode at the desired location. It must be
positioned perpendicular to the welding location to pre-
vent slippage. Apply sufficient force to prevent any gap
between the two parts. Pull trigger of pistol to begin
welding process. Release trigger to stop. After welding
is completed, hold pistol in place for approximately 2
seconds to create a forging effect and avoid rapid cool-
ing of the spot.
NOTE: Pulsations are not recommended for single side
welding except for thick metal. Therefore, for welding of
high strength steel, use the same program and same
settings as those for zinc coated steel.
