Product Description

The industrial welder transformer is a buck boost transformer. When the power is connected, the low voltage and high current can be obtained. When the welding rod is in contact with the welding part, the power supply is short circuited and the arc is ignited. The heat source of the arc will fuse the gap and electrode of the workpiece in the high temperature of the arc.

The transformer uses high quality and high conductivity materials and advanced vacuum impregnation equipment and professional production technology. The products have energy saving, low loss, low noise, impact resistance and short circuit resistance. Strong overload capacity, compact structure, small volume, reliable power supply and so on.
