1. Energy saving more than 35% compared to AC welder in same conditions. Environmental friendly, energy saving.
2. Less capacitor is required with balanced three-phase loading and high power factor.
3. Welding quality has improved significantly. With strong secondary current output capability, straight waveform, small peak current. The electrode's heating is small, thus service life has extended.
4.Power charging time can accurate to 1ms, it's 1/20 of the AC welder.
Welding parameters are more accurately set.
5.DC output, various program selection. This welder can achieve complex welding process. It's widely used in dissimilar metal welding.
6. Welding circuit is small and light-weight. The size of MFDC transformer is only 1/3 - 1/6 of single-phase rectifier transformer.
7. Key components are imported high-quality ones. By using placing machine and reflow furnace to make circuit board, welders' reliability are high.
1. Apply in welding automotive wheel nut cap, stainless steel cap and similar products.
2. Projection and nut welding can be done after modification.
