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.
3. 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.
SPOT WELDING INSTRUCTIONS
1. Select the wire diameter and heat setting
recommended above for the method of
spot welding you intend to use.
2. Tune in the wire speed as if you were
going to make a continuous weld.
3. Hold the nozzle piece completely
perpendicular to and about 1/4 inch off
the work piece.
4. Pull the trigger on the gun and release it
when it appears that the desired penetra-
tion has been achieved.
5. Make practice spot welds on scrap metal,
varying the length of time you hold the
trigger, until a desired spot weld is made.
6. Make spot welds on the actual work piece
at desired locations.

MAINTENANCE

GENERAL

This welder has been engineered to give
many years of trouble-free service providing
that a few very simple steps are taken to
properly maintain it.
1. Keep the wire drive compartment lid
closed at all times unless the wire needs
to be changed or the drive tension needs
adjusting.
2. Keep all consumables (contact tips, noz-
zles, and gun liner) clean and replace
when necessary. See CONSUMABLE
MAINTENANCE and TROUBLESHOOT-
ING later in this section for detailed
information.
3. Replace power cord, ground cable,
ground clamp, or gun assembly when
damaged or worn.
4. Periodically clean dust, dirt, grease, etc.
from your welder with a damp rag. Every
six months, or as necessary, remove the
side panels from the welder and air-blow
any dust and dirt that may have accumu-
lated inside the welder.
WARNING
Electric shock can kill! To reduce the risk
of electric shock, always unplug the welder
from its ac power source before removing
side panels.

CONSUMABLE MAINTENANCE

IT IS VERY IMPORTANT TO MAINTAIN THE
CONSUMABLES TO AVOID THE NEED
FOR PREMATURE REPLACEMENT OF
THE GUN ASSEMBLY.
The GUN LINER is intended to provide an
unrestricted path for the welding wire to flow
through the gun assembly. Over time the
liner will accumulate dust, dirt, and other
debris. Replacement is necessary when
these accumulations begin to restrict the free
flow of wire through the gun assembly.

MAINTAINING THE CONTACT TIP

The purpose of the CONTACT TIP is to
transfer welding current to the welding wire
while allowing the wire to pass through it
smoothly.
