120V SPOT WELDER
ADJUSTING TONG PRESSURE
WARNING
:
Turn the Welder OFF and disconnect from
power prior to adjusting Tong Pressure.
NOTE:
Use a clamp or vise to hold workpieces together.
Excessive pressure can damage Electrode Tips.
Problem
Indications
Solution
Tong
Pressure is
Too Weak
• Workpieces are loose
between Electrode
Tips when the Tongs
are closed
• No weld formed
Loosen the Front Jam
Nut, when the desired
pressure is reached,
tighten the Rear Jam
Nut to meet the Upper
Tong Holder
Tong
Pressure is
Too Strong
• Weld will dimple/
concave
• Molten material
pushes out from weld
point
Loosen the Rear Jam
Nut, when the desired
pressure is reached,
tighten the Front Jam
Nut to meet the Upper
Tong Holder
WELDER OPERATING INSTRUCTIONS
WARNING
:
DO NOT touch the Upper or Lower Tongs
while operating.
NOTE:
These instructions describe very basic welding processes
as they apply to the operation of this Welder. There are many
different types of welding machines, welds and welding
procedures that cannot be described in detail by this instruction
manual. Proficiency in welding requires practice, education
and testing. DO NOT rely solely on this product manual for
instructions on proper welding technique. By using this product,
the operator understands that OEMTOOLS™ cannot be held
responsible for property damage caused by operator negligence,
ignorance or general welding mistakes.
1. Thoroughly read and understand warnings and Welder
installation instructions.
2. Inspect the Spot Welder for any broken parts, loose
hardware, visibly damaged wiring or other condition
that may affect the Spot Welder’s performance.
3. BEFORE PLUGGING IN THE WELDER, lower the
Operating Lever to contact the workpieces between the
Upper and Lower Tong to ensure there are no gaps or
misalignments.
4. Properly dress Electrode Tips and align Upper and
Lower Tongs.
5. Inspect the workpieces for any coating, paint, greases,
oils, residue or dusts that could affect the weld or
safety of the operator.
6. Plug the Spot Welder into a grounded 120V AC outlet.
PRESS and HOLD the Power Switch to the side.
Lower the Operating Lever, to initiate contact with the
workpiece and create spot weld.
NOTE:
Weld time is based on the workpiece material and
thickness. The operator’s experience and knowledge of spot
welding and welding processes can factor into the quality of
the weld.
7. Raise the Operating Level after each weld to terminate
contact between the Electrode Tips and workpiece.
8. RELEASE the Power Switch.
9. Unplug the Spot Welder from the power source.
DRESSING ELECTRODE TIPS
WARNING
:
Allow Electrode Tips and workpiece to cool prior
to handling.
WARNING
:
Turn the Welder OFF and disconnect from power
prior to performing maintenance on the Electrode Tips.
1. Prior to each use, inspect Electrode Tips for
deformation.
2. Use a file or specialized tip dresser to restore the
diameter (3/16" or 4.75 mm) and approximate face
angle to the specifications of a new Electrode Tip.
NOTE:
File and tip dresser are not included with this product.
3. Replace used electrode tips that cannot be dressed.
Deformed Electrode Tips cannot make proper contact,
leading to weak/faulty welds.
d = 3/16" (4.75 mm) diameter
REPLACING ELECTRODE TIPS
WARNING
:
Turn the Welder OFF and disconnect from
power prior to replacing Electrode Tips.
1. Remove used Electrode Tips from Upper and
Lower Tongs.
2. Screw the new Electrode Tips into the Upper and
Lower Tongs
DUTY CYCLE
To avoid damage and personal injury, DO NOT weld for
longer than the prescribed Duty Cycle Time. This Welder has
a 50% Duty Cycle Time at 1.5kVA based on a 10 second
time period. This indicates that this Welder can weld for
5 seconds out of every 10 second time period. Failure to
comply may lead to product failure.
