Diagram.) WASHER HANDLE (#17) BOLT (#19) HEX NUT (#20) HANDLE BRACKET (#18) FIGURE C POWER SWITCH (#25) (#25) HEX SCREW (#16) FIGURE D To Attach Tong Tips To The Spot Welder: 1. Caution: Prior to attaching the Tong Tips (parts #48), make sure the Spot Welder is disconnected from its electrical power source. 2. To attach the Tong Tips (part #48) to the Upper and Lower Tongs (parts #46, #47), screw the Tips onto the Tongs as shown in Figure E. UPPER TONG (#46) LOWER TONG (#47) TONG TIP (#48) FIGURE E SKU 45690 PAGE 7 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.) SKU 45690 PAGE 8 OPERATING LEVER (#5) REAR HEX JAM NUT (#10) CAP SCREW (#3) FRONT HEXT JAM NUT (#10) UPPER TONG (#46) HEX NUT (#20) TONG TIP (#48) FIGURE F LOWER TONG (#47) 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.) SKU 45690 PAGE 9 RECOMMENDED PRACTICES FOR SPOT WELDING LOW-CARBON STEEL 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. SKU 45690 PAGE 10 3. Do not use solvents to wipe off the Spot Welder, as damage may re...
