Frequently Asked Questions - HD-50 Vevor

How to adjust the table rotation speed?

Use the speed adjustment potentiometer (K4) located on the control box. Turn it clockwise to increase speed, counterclockwise to decrease it. The speed range is 0.5 to 6 rpm.

What to do if the motor does not turn?

First check the power supply and fuse. If the motor receives power but does not turn, replace the motor. If the control board has no output, check the transformer or replace the control board.

How to maintain the turntable?

Pour lubricating oil weekly through the provided lubrication hole. Regularly check the condition of cables and connections.

What are the essential safety precautions?

Always wear leather gloves, an apron, safety shoes, a welding helmet with arc filter, and protective goggles. Do not wear jewelry. Ensure the equipment is properly grounded and avoid humid environments.

How to use the foot switch?

Plug the foot switch into the designated socket. It allows starting and stopping rotation without using hands, freeing your hands for welding. If the switch does not work, check its condition or replace it.

How to change the table rotation direction?

Use the forward/reverse switch (K2) located on the control box. Toggle it to reverse the motor rotation direction.

What to do if the power switch does not light up?

Check the power fuse: if blown, replace it. Also check the LED: if burnt out, replace it. If the switch is defective, replace it. Ensure the device is properly plugged in.

How to install the turntable?

Place the table on a stable surface. Secure it to the workbench using the provided M8x20 mounting bolts. Ensure the center hole is aligned if necessary. Connect power and accessories according to the diagram.

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.

The compressed air power must be cut off and turned off before the maintenance 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 that the operator does not have any contact, protection or wet clothing with the metal parts to be welded.
4. Avoid contact with welded parts.
5. Do not spot weld in very wet places or on wet floors.
6. Do not weld with worn cables. Check that the insulation is not damaged and that connections are not loose.
7. Turn off the device before replacing the electrode.
8. Disconnect the equipment before servicing or repairing it.

Protection of Eyes and Body:

1. During welding, wear leather gloves, a welding apron, safety shoes, welding protective clothing, and a helmet or glasses with arc filtering and radiation protection. The operator must protect their eyes during chipping and hammering.
2. Do not wear rings, watches, or jewelry. They can cause burns.
3. All protective shields must be in good condition and in proper position. Without eye protection, do not look at the welding arc. Protect the area near the product from sparks and reflections.
