2. Safety Instructions
Always prioritize safety when operating welding equipment. Failure to follow these instructions may result in serious injury or equipment damage.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, including welding gloves, a welding helmet with proper shade, safety glasses, and protective clothing to shield against sparks, heat, and UV radiation.
- Ventilation: Ensure adequate ventilation in the work area to disperse welding fumes. Avoid inhaling fumes directly.
- Fire Hazards: Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
- Electrical Safety: Ensure the power supply matches the equipment's requirements (AC 230V 50Hz). Do not operate with damaged cables or plugs. Avoid welding in damp or wet conditions.
- Workpiece Preparation: Clean the surface of the sheet metal thoroughly before welding to improve weld strength and prevent contamination.
- Overheat Protection: The unit features an intelligent overheat protection system that activates at 95°C (203°F). If activated, allow the unit to cool down before resuming operation.

5. Setup
Before operating the VEVOR Spot Welder, ensure proper setup for safety and optimal performance.
- Unpacking: Carefully remove all components from the packaging. Verify that all items listed in the "Product Overview" section are present.
- Placement: Place the main welder unit on a stable, dry, and level surface. Ensure adequate space around the unit for ventilation.
- Power Connection: Connect the power cable to a grounded AC 230V 50Hz power outlet. Ensure the power switch on the unit is in the "OFF" position before plugging in.
- Welding Gun Connection: Securely attach the welding gun cable to the designated port on the main unit.
- Ground Clamp Connection: Attach the ground clamp securely to a clean, bare metal section of the vehicle body, close to the repair area. A good ground connection is crucial for effective welding.
- Accessory Selection: Choose the appropriate electrode or accessory (e.g., pulling stud, wave line electrode) for the specific dent repair task and attach it to the welding gun.
6. Operating Instructions
The VEVOR Spot Welder features 6 functional modes and automatic contact welding for ease of use.
- Power On: Flip the main power switch to the "ON" position.
- Surface Preparation: Thoroughly clean the dented area of the vehicle body. Remove any paint, rust, or contaminants to expose bare metal. This is critical for a strong weld.
- Select Mode: Use the control knob on the front panel to select one of the 6 functional modes based on the type of dent and repair required. The available modes are:
- Round Joint: Suitable for pointed deep dents.
- OT Joint: Suitable for shallow dents.
- Wave Line: Suitable for long, straight dents.
- Hot Press Flattening: For flattening raised surfaces.
- Carbon Rod: For thermal annealing (shrinking stretched metal).
- Spot Welding Slide Hammer: For small area dents.
- Adjust Power: Adjust the welding power using the corresponding control. Start with a lower setting and increase as needed.
- Automatic Contact Welding: The unit features automatic contact welding. Once the welding gun's electrode makes firm contact with the workpiece, the welding process will initiate automatically. There is no manual trigger required for welding.
- Welding Process:
- Place the chosen accessory (e.g., pulling stud) onto the welding gun.
- Press the accessory firmly against the cleaned metal surface of the dent.
- The welder will automatically detect contact and perform the spot weld.
- Once welded, use the appropriate pulling tool (e.g., slide hammer, pulling hook) to pull the dent out.
- Repeat the process as necessary across the dented area.
- Power Off: After use, turn the main power switch to "OFF" and unplug the unit from the power outlet.

7. Maintenance
Regular maintenance ensures the longevity and reliable performance of your VEVOR Spot Welder.
- Cleaning: After each use, clean the welding gun, electrodes, and main unit to remove any welding spatter or debris. Use a dry cloth; do not use solvents that could damage plastic components.
- Cable Inspection: Regularly inspect all cables and connections for signs of wear, cuts, or damage. Replace any damaged cables immediately.
- Electrode Condition: Check electrodes for wear. Worn electrodes can affect weld quality. Replace them as needed.
- Ventilation Openings: Ensure the ventilation openings on the main unit are clear of dust and obstructions to prevent overheating.
- Storage: Store the unit and its accessories in a dry, clean environment, preferably in the provided tool box, when not in use.
8. Troubleshooting
This section addresses common issues you might encounter during operation.
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | No power supply; power switch off; damaged cable. | Check power outlet; ensure power switch is ON; inspect and replace damaged cables. |
| No weld occurs when electrode touches workpiece. | Poor ground connection; dirty workpiece surface; incorrect power setting; worn electrode. | Ensure ground clamp is securely attached to clean metal; clean workpiece surface thoroughly; increase power setting; replace electrode. |
| Unit overheats and shuts down. | Continuous operation beyond duty cycle; blocked ventilation. | Allow unit to cool down; ensure ventilation openings are clear. Reduce continuous operating time. |
| Weak or inconsistent welds. | Insufficient power; dirty surface; improper contact pressure; incorrect mode selection. | Increase power; clean surface; apply firm, consistent pressure; verify correct mode for the task. |
