Frequently Asked Questions - VR230 Vevor

What type of current does the Vevor VR230 use?

The VR230 uses alternating current (AC) input (220-240 V) and delivers a welding current output of 1-7 V AC with a maximum instantaneous current of 3500 A.

Can I use this welder on all types of car bodies?

Yes, it is designed for dent repair on auto bodies. The supported sheet metal thickness is 0.6 to 1.2 mm. Adjust the welding mode and power according to the thickness.

How to adjust the power and welding time?

Use the adjustment knobs on the front panel: Power and Time. There are 7 preset channels. For each mode, a default value is suggested (e.g., mode 3, power 6, time 5). Adjust according to the sheet thickness to avoid piercing the workpiece.

What to do if the machine stops during operation?

This may be due to overheating. The thermal protection automatically shuts off the device. Allow the machine to cool for a few minutes before restarting. Also check that the trigger is not loose and the control cable is not damaged.

What safety precautions should I follow?

Always wear insulating gloves, a welding mask with filter, flame-resistant clothing, and insulating shoes. Ensure the work area is well ventilated and free of flammable materials. Never weld on a container that has held flammable liquids.

How to install the ground cable (negative lead)?

Attach the negative lead (ground clamp) to a clean and bare part of the car body, close to the welding area. Remove paint or rust to ensure good electrical contact. The closer the connection, the better the result.

Can the VR230 be used for applications other than dent removal?

Yes, it also allows carbon rod heating (to expand metal), hot pressing, and stud welding. Each mode is accessible via the channel selector.

How to maintain the machine?

After each use, clean the electrodes and welding heads. Check the condition of the power cable (minimum cross-section 4 mm²). Store the device in a dry place. Replace worn parts (carbon rods, pads) with original parts.

Does the machine have overload protection?

Yes, the VR230 includes overheat protection. If the internal temperature becomes too high, the power is automatically cut off until the machine cools down. This protects the electronic components.

Where can I find warranty and technical support?

Visit www.vevor.com/support to obtain the electronic warranty certificate and contact customer service. Keep the proof of purchase.

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' protection of electrical and electronic procedures (on-board computers, on-board radios, alarms, airbags, etc.)

The compressed air power must be cut off and turned off before the main operation is carried out.

Electrodes, electrode arms and other secondary conductors can reach very high temperatures and stay high for a long time after stopping the machine. Pay attention to scald.

Preventive maintenance is necessary on a regular basis.

Power Connection:

1. Check that the device must be connected to the ground coupler and to the ground. It is in good condition.
2. Check if the workbench is connected to the ground connector. 3. Ensure the operator does not have any contact, protection or wet clothing with the metal

to be welded.

1. Avoid contact with welded parts.
2. Do not spot weld in very wet places or on wet floors.
3. Do not weld with worn cables. Check that the isolation belt does not have default cable or that the connection is loose.
4. Please turn off the device before replacing the electrode.
5. Please disconnect the equipment directly 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 an arc-filtering and radiation-protective helmet or glasses. The operator must protect their eyes during rubbing and hammering.
2. Do not wear rings, watches, or jewelry. They can cause burns.
3. All protective boards must be in good condition and in proper position. Without eye protection, do not look at the welding arc. Protect the environment near the product from projection and reflection.

Welding Fume:

Welding operations can lead to the emission of toxic smoke and harmful metals. The equipment should be installed in covered areas with smoke extractors.

Operators must wear smoke masks. Welding materials must be cleaned.

Pay Attention to Fire:

1. Check whether sparks cause fires, especially in the vicinity of flammable materials.
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 or lubricant materials, 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 devices.
• No active medical devices (pacemakers, acoustic prostheses) were used nearby (at least 3 meters away).

Select the appropriate welding mode.

Adjust the power and time as needed (the default is 5 and 5). You can increase or decrease these values according to the actual situation.

Heat the workpiece in a clockwise direction.

Use cold water or a wet cloth on the heated area to take advantage of thermal expansion and contraction, which helps to tighten the prominent part and return it to normal.

Note:

1. Before performing this operation, test on other parts to avoid using excessive current or time, which could damage the body or the repair surface.
2. Select the appropriate gear according to the thickness of the body panel. The main unit will automatically match the welding time with the current.
3. After performing this operation, you can proceed with other functions. If you do not need to continue working, please turn off the power and disconnect the main switch, and tidy up all accessories for the next use.

d. Wave line welding

Attach the negative cable to the workpiece that has been polished and cleaned, with paint removed. The closer to the operating surface, the better.

Connect the triangular pull hammer to the torch and lock it in place.

Select the appropriate welding mode.

Adjust the appropriate power and time (the default values are 8 and 7). They can be increased or decreased according to the actual situation.

Place the waveform line upright in the car body and place the welding head on the upright waveform line. The machine will automatically weld.

Use a claw pull hook and hammer set on the waveform line to pull out the car body depression.

Note:

1. Before doing this operation, please first test on other parts to avoid the current being too large or the time too long, which could damage the repaired body surface.
2. According to the body plate thickness, select the appropriate gear. The machine will automatically match the welding time with the current.
3. After doing this operation, you can continue to other functional operations. If you do not continue to work, turn off the power and cut off the main switch. Arrange the various accessories for the next use.
