How to prevent safety accidents with the butt welder?

The secondary voltage of the welding machine typically remains low. However, if there is a break in the primary winding of the welding transformer, or the insulation between the primary winding and the secondary winding is damaged, or if the control device is exposed to moisture or experiences insulation damage, then the secondary voltage may be affected.

In order to better prevent electric shock, welding transformer secondary winding, machine case and control device shell should be reliably grounded, with grounding multi-copper bare wire cross-sectional area of not less than 4 square millimeters and clad copper wire cross-sectional area of not less than 5 square millimeters.

When running, the door of the machine and control box should be closed. In many cases, the electrode is externally water-cooled. Therefore, users should wear insulated rubber shoes when running. When many people are running at the same time, they should tell others that they have to energize or increase the voltage.

Metal particles and fumes from the welding process can contaminate the air. In addition to trying to select or not to select copper alloys containing harmful elements (such as cadmium, etc.) as electrodes, local ventilation (exhaust) forms are now more common to ensure a clean environment for use.
