Welding machine manual switch wiring

Welding machine switch wiring diagram:

The high-temperature arc generated by the instantaneous short circuit between the positive and negative electrodes is used to melt the solder and the material to be welded on the electrode, so as to achieve the purpose of combining the two. The welding machine has a simple structure. High-power transformer can turn 220/380V AC into low-voltage and high-current power supply, which can be DC or AC.

Extended data welding machine safety operation procedures

(1) Welding operators and cooperating personnel must wear labor protection articles according to regulations. Safety measures must be taken to prevent accidents such as electric shock, falling, gas poisoning and fire.

(2) The electric welding machine used on site shall have a rain-proof, moisture-proof and sun-proof shed, and be equipped with corresponding fire-fighting equipment.

(3) Flammable and explosive articles such as oil, wood, oxygen cylinders and acetylene generators shall not be piled up within the welding site 10m.

(4) Before use, check to make sure that the primary and secondary wires are connected correctly, and the input voltage meets the requirements of welding machine nameplate. After the power is connected, it is forbidden to touch the live part of the primary line. The primary and secondary connections must be equipped with protective covers.

(5) The secondary tap connection copper plate should be compacted, and the terminal should have gaskets. Before closing, carefully check the connecting nuts, bolts and other parts to ensure that they are intact and free from looseness or damage. There is a protective cover on the terminal.
