Frequently Asked Questions - 90E Vevor

How to use the Vevor 90E welder to repair a car body dent?

To repair a dent, use the Joint Welding mode (code 2) or Triangular Welding mode (code 1). Attach the ground clamp to a clean, degreased surface. Select the appropriate mode on the panel, adjust the power according to the sheet thickness (e.g., power 4-5 for 0.8 mm). Place the welding gun on the repair piece (washer or tab) and press to weld. Then remove the piece with the pull hammer.

What power setting for a 0.8 mm thick sheet?

For a 0.8 mm sheet, start with a power of 4 out of 5 for joint welding (code 2) or triangular welding (code 1). The machine automatically adjusts the welding time. If the weld is too weak, gradually increase the power. Always test on a scrap piece before working on the body.

How to change the welding mode on the 90E welder?

Use the Welding Mode button on the control panel to scroll through the 7 channels. Each channel corresponds to a welding type: 1 = triangular, 2 = joint, 3 = OT joint, 4 = wave line, 5 = hot pressing, 6 = carbon rod, 7 = studs. Confirm with the Mode Confirmation button. You can also switch between automatic and manual modes.

What to do if the machine does not weld?

First check that the power is properly connected and the switch is on. Ensure the gun trigger works and the control wire is not broken or disconnected. Also check that the ground clamp is securely connected to a clean metal surface. If the problem persists, refer to the troubleshooting table in the manual.

How to connect the ground clamp?

Attach the ground clamp to a clean, bare metal part of the car body, if possible near the welding area. Remove paint, rust, or grease to ensure good electrical contact. A poor connection can cause weak welds or sparks.

How to use the included suction cup?

The manual suction cup is used to extract small dents without welding. Place the suction cup at the center of the dent, press firmly to create a vacuum, then pull the pull hammer in the opposite direction to lift the depression. For blind spots, use the forced suction cup with the hammer.

What is the procedure for carbon rod heating?

Select mode 6 (Carbon Rod Heating). Attach the ground clamp to a clean surface. Insert the carbon rod into the designated head and connect it to the gun. Heat the repair area by moving the rod clockwise. Then quickly cool with a damp cloth to cause thermal expansion/contraction and pop out the dent.

How to avoid machine overheating?

The machine is equipped with thermal protection that automatically shuts it down in case of overheating. To avoid it, respect the duty cycle: do not weld continuously for more than a few seconds, let it cool between operations. Ensure the ventilation slots are not blocked. If it shuts down, wait for the machine to cool before resuming.

What accessories are included with the Vevor 90E welder?

The kit includes: main unit, tool box, pull hammer, welding gun, 10 corrugated wires, a meson head, a carbon rod head, a spot welding head, 2 carbon rods, a wrench, a pull hook, a six-jaw hook, 10 triangular tabs, 10 long spacers (OT), 20 round spacers, and a suction cup.

General safety rules:

Before removing the body of the product, pull out the wire first.

The operator must be qualified accordingly.

The operation can only be controlled by qualified technicians.

Operators are responsible for complying with automotive manufacturers' protective procedures for electrical and electronic systems (on-board computers, on-board radios, alarms, airbags, etc.).

The compressed air supply must be shut off and the machine turned off before maintenance operations are carried out.

Electrodes, electrode arms, and other secondary conductors can reach very high temperatures and remain hot for a long time after the machine is stopped. Beware of scalding.

Preventive maintenance is necessary on a regular basis.

Power Connection:

1. Check that the device is properly connected to the ground coupler and that the ground connection is in good condition.
2. Check if the workbench is connected to the ground connector. Ensure that the operator does not have any contact with the metal to be welded, and that they are not wearing protective or wet clothing.
3. Avoid contact with welded parts.
4. Do not spot weld in very wet places or on wet floors.
5. Do not weld with worn cables. Check that the insulation does not have defects and that connections are not loose.
6. Turn off the device before replacing the electrode.
7. Disconnect the equipment before it is controlled or repaired.

Protection of Eyes and Body:

1. During welding, wear leather gloves, a welding apron, safety shoes, welding protective clothing, and arc-filtering and radiation-protective helmets or glasses. The operator must protect their eyes during grinding and hammering.

2. Check that the fire extinguisher is not far from the operator.
3. Place the equipment where there are pneumatic devices.
4. Do not weld on a container with flammable and lubricant, even if it is empty.
5. Do not weld in an atmosphere filled with flammable gas or fuel vapor.

Electromagnetic Compatibility:

Near the welding site, check:

• There are no other power cords, control cables, telephone lines, radio or television reception equipment, watches, mobile phones, magnetic cards, computers or any other electronic device.
• No active medical devices (pacemakers, acoustic prostheses) were used around (at least 3 meters).
