SPECIFIC PRODUCT WARNINGS AND PRECAUTIONS

1. GROUND THIS PRODUCT. The required electrical Power Cord Plug for this

product is a grounded, 230 Volt, 3-Prong Plug (not included). It is recommended

that only a qualiﬁed technician connect a Power Cord Plug to the Power Cord. Never

remove the grounding prong or modify the Plug in any way. Do not use adapter

plugs with this product. When in use, make sure this product is always plugged into

a grounded, 230 Volt, 3-hole electrical receptacle with an appropriate breaker switch

inline.

2. MAKE SURE THE CONTROL SWITCH (part #25) IS IN THE “OFF” POSITION

BEFORE PLUGGING IN THE POWER CORD. (See Figure D, and Assy.

Diagram.)

3. DO NOT ABUSE THE POWER CORD. Do not use the Cord to pull the 3-Prong Plug

from a power outlet. Keep Cord away from heat, oil, sharp edges, and moving parts.

Replace damaged Cord immediately. Route the Power Cord safely. Protect it from

being damaged by other equipment in the shop. Do not route the Cord where it can

be walked on or tripped over.

4. MAINTAIN A SAFE WORK ENVIRONMENT. Do not use this product in or near

damp or wet areas. Do not expose this product to rain. Keep work area well lit.

Make sure there is adequate surrounding work space. Use this product in a well

ventilated area. (Read Material Safety Data Sheets/MSDS for metals, coatings, and

cleaners.) Do not operate this product in the presence of ﬂammable liquids, gases,

or dust. To avoid accidental electric shock, do not let your body come in contact with

grounded surfaces such as pipes, radiators, ranges and refrigerators. Always keep

a ﬁre extinguisher nearby.

8. DO NOT OVERREACH. Keep proper footing and balance at all times to prevent

tripping, falling, back injury, etcetera.

9. STAY ALERT. Watch what you are doing at all times. Use common sense. Do not

ASSEMBLY INSTRUCTIONS

NOTE: For additional references to the parts listed below, refer to the Assembly

Diagram on page 13 of this manual.

To Attach The Upper And Lower Tongs:

1. Caution: Prior to attaching the Upper and Lower Tongs (parts #46, #47), make

sure the Spot Welder is disconnected from its electrical power source.

2. NOTE: Make sure the Upper and Lower Tongs (parts #46, #47) are clean and not

corroded before installing. If necessary, clean the Tongs with steel wool.

3. To attach the Lower Tong (part #47) to the Spot Welder, loosen the four Cap

Screws (part #3) located at the bottom/front of the tool. (See Figure A, and Assy.

Diagram.)

4. Slide the Lower Tong (part #47) between the Tong Insulator (part #33) and Lower

Tong Clamp (part #35), and position the Lower Tong so that the Tong Tip (part #48)

faces up.

5. NOTE: Check to make sure the Lower Tong (part #47) will align with the Upper

Tong (part #46) when fully assembled. (See Figure B, and Assy. Diagram.)

6. Re-tighten the four Cap Screws (part #3).

7. To attach the Upper Tong (part #46) to the Spot Welder, loosen the four Cap Screws

(parts #3, #11) located at the top/front of the tool. (See Figure A, and Assy.

Diagram.)

8. Slide the Upper Tong (part #46) between the Tong Tip Holder (part #12) and Upper

Tong Clamp (part #13), and position the Upper Tong so that the Tong Tip (part #48)

faces down.

9. NOTE: Check to make sure the Upper Tong (part #46) will align with the Lower

Tong (part #47) when fully assembled. (See Figure B, and Assy. Diagram)

To Attach The Handle To The Spot Welder:

1. To attach the Wooden Handle (part #17) to the Spot Welder, insert the Bolt (part

#19) through the following parts in this order: through a Handle Bracket (part #18),

through the Wooden Handle, and through the remaining Handle Bracket. Then,

secure the parts together, using the Lock Washer (part #49) and Hex Nut (part #20).

(See Figure C, and Assy. Diagram.)

SKU 45690 PAGE 6

2. Next, Attach the complete Handle Assembly (parts #17, #18, #19, #20) to the Front

Housing (part #28) of the Spot Welder, using the four Hex Head Screws (part #16).

OPERATING INSTRUCTIONS

NOTE: For additional references to the parts listed below, refer to the Assembly

Diagram on page 13 of this manual.

To Adjust The Tong And Operating Lever Pressure:

1. Caution: Prior to adjusting the Tongs (parts #46, #47) and Operating Lever (part

#5) pressure, make sure the Spot Welder is disconnected from its electrical supply

source.

2. NOTE: Excessive Tong (parts #46, #47) can damage the Tong Tips (part #48).

Do not use the Tongs as a clamp or vice to hold the workpieces together. If the

workpieces to be welded do not make good contact at the point of the intended

weld, clamp the workpieces together to provide good contact between the surfaces.

(See Figures A, and Assy. Diagram.)

3. The Tongs (parts #46, #47) pressure is adjustable, and should be checked and/or

set before operation. Correct Tong pressure is necessary to create a proper weld

and to prevent damage to the Tong Tips (part #48). (See Figures A, F, and Assy.

Diagram.)

4. If the Tongs (parts #46, #47) pressure is too weak, and the workpieces are loose

when the Tongs close severe arcing will occur between the workpieces and no weld

can be made. To increase the Tong pressure, loosen the front Hex Jam Nut (part

#10). The more the front Hex Jam Nut is loosened, the greater the pressure on the

Tong Tips (part #48) when the Operating Lever (part #5) is closed. Next, turn the

rear Hex Jam Nut toward the Top Tong Clamp (part #13) to lock the desired pressure

in position. (See Figures A, F, and Assy. Diagram.)

5. If the Tongs (parts #46, #47) pressure is too strong, the weld nugget will dimple,

and material will splash out around the nugget area. To decrease the Tong

pressure, loosen the rear Hex Jam Nut (part #10) and turn the front Hex Jam Nut

(part #10) toward the Top Tong Clamp (part #13) to lock the desired pressure in

position. (See Figures A, F, and Assy. Diagram.)

6. The farther down the Cap Screw (part #3) is turned, the farther down the Operating

Lever (part #5) will close. Adjusting the Cap Screw will determine if the Tongs (parts

#46, #47) lock on the material, or just pull up tight. Adjust the Cap Screw to allow

the Operating Lever to be raised easily after the weld has been completed. (See

Figures A, F, and Assy. Diagram.)

7. To adjust the pressure required to push down the Operating Lever (part #5), turn the

Hex Nut (part #20) located on each side of the Front Housing (part #28) clockwise

or counterclockwise. (See Figures A, F, and Assy. Diagram.)

To Use The Power Switch:

1. The Power Switch (part #25) allows electrical current to the Spot Welder to be turned

“ON” and “OFF”. (See Figure D, and Assy. Diagram.)

2. Turn the Power Switch (part #25) sideways in either direction to start the electrical

current. Release the Power Switch to stop the electrical current.

To Use The Operating Lever:

1. Caution: Never touch the Upper and Lower Tongs (parts #46, #47) when

welding a workpiece. Allow the Tong Tips (part #48) and the workpiece to cool

before handling. (See Figures A, B, E, and Assy. Diagram.)

2. The Operating Lever (part #5) allows you to open and close the Upper and Lower

Tongs (parts #46, #47). (See Figures A, F, and Assy. Diagram.)

3. Close the Operating Lever (part #5) during the welding process to compress the

workpieces between the Tong Tips (part #48). Open the Operating Lever after the

spark appears and each weld is made to release the workpieces. (See Figures B,

A, F, and Assy. Diagram.)

TROUBLE SHOOTING GUIDE

INSPECTION, MAINTENANCE, AND CLEANING

1. Caution:Always disconnect the Spot Welder from its electrical power supply source

before performing any inspection, maintenance, or cleaning.

2. Before each use, inspect the general condition of the Spot Welder. Inspect switch,

power plug and cord assembly, and extension cord (if used) for damage. Check for

loose screws, misalignment, binding of moving parts, broken parts and any other

condition that may affect its safe operation. If abnormal noise or vibration occurs,

disconnect the Spot Welder from its electrical supply source immediately and have

the problem corrected before further use. Do not use damaged equipment.
