i. The BURN-THROUGH METHOD welds two overlapped pieces of metal
ii. The PUNCH AND FILL METHOD produces a weld with the most finished

7. SPOT WELDING INSTRUCTIONS
a. Select the wire diameter and heat setting recommended above for the method of spot
welding you intend to use.
b. Tune in the wire speed as if you were going to make a continuous weld.
c. Hold the nozzle piece completely perpendicular to and about 1/4 inch off the work
piece.
d. Pull the trigger on the torch and release it when it appears that the desired
penetration has been achieved.
e. Make practice spot welds on scrap metal, varying the length of time you hold the
trigger, until a desired spot weld is made.
Make spot welds on the actual work piece at desired locations.
f.
ELECTRIC SHOCK CAN KILL!
Touching live electrical parts can cause fatal shocks or severe burns. Do not touch live
electrical parts
Wear dry, hole-free insulating gloves and body protection.
Disconnect input power before installing, maintaining or servicing this equipment.

together by burning through the top piece and into the bottom piece. With the
burn-through method, larger wire diameters tend to work better than smaller
diameters. Wire diameters that tend to work best, with the burn-through
method are 0.035 inch self-shielding flux-core wire. Do not use 0.030 inch
self-shielding flux core wires when using the burn-through method unless the
metal is VERY thin or excessive filler metal build-up and minimal penetration
is acceptable. Always select the HIGH heat setting with the burn-through
method and tune in the wire speed prior to making a spot weld.
appearance of the three spot weld methods. In this method, a hole is
punched or drilled into the top piece of metal and the arc is directed through
the hole to penetrate into the bottom piece. The puddle is allowed to fill up
the hole leaving a spot weld that is smooth and flush with the surface of the
top piece. Select the wire diameter, heat setting, and tune in the wire speed
as if you were welding the same thickness material with a continuous bead.

Select the wire diameter, heat setting, and tune in the wire speed as if you
were welding the same thickness material with a continuous bead.
