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.
ii. The PUNCH AND FILL METHOD produces a weld with the most finished
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 the bottom piece. The puddle can 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.
iii. The LAP SPOT METHOD directs the welding arc to penetrate the bottom and
top pieces, at the same time, right along each side of the lap joint seam. 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.
5. 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.
f. Make spot welds on the actual work piece at desired locations.
DC STICK OPERATION
⚠WARNING
High voltage danger from power source!
• Consult a qualified electrician for proper installation of receptacle at the power source. This welder
must be grounded while in use to protect the operator from electrical shock. If you are not sure if
your outlet is properly grounded, have it checked by a qualified electrician. Do not cut off the
grounding prong or alter the plug in any way and do not use any adapter, other than the supplied
adapter, between the welder's power cord and the power source receptacle. Make sure the power
switch is OFF then connect your welder's power cord to a properly grounded 230 VAC (220V -
240V), 60 HZ, single phase, 50-amp power source. If operating on 120V, attach the 120V Adapter
cord to the unit power cord and then connect the assembly to a properly grounded 120 VAC (110V-
130V), 60 Hz, single phase, 25-amp power source.
