Features:
- Functions are controlled by a DSP chip and can save 30 sets of parameter
- Automatic switch off in over-current, over/under-voltage, over-heat, phase lacking
- Support fast forward selection on the front panel
- Suport MMA,MIG/MAG and Hi-speed MIG/MAG welding
- Stable pulse welding can be realized with 50A current and Φ1.2mm wire
- Very suitable for mid/thick plate pulse welding with Φ6mm wire
- Can be used with robot to realize automatic welding
- With such functions as primary current/voltage adjustment, 4T current/voltage adjustment, integral/off
selection, saving and reading of welding parameter, spot welding set
- With robot interface and group control interface
- First in China: Hi-speed DC welding
Advantages:
A．In bottom welding, the backside of welding seam is also good, the defects can be avoided
B．Penetration about 20% bigger than the general DC MIG/MAG welding in the big current welding (300A)
C．Welding speed is 15% higher than the general MIG/MAG welding
D．In fillet welding, welding meat is flat and smooth, no bulge
- Iron water flows smoothly and is easy to control in covering welding
- Suitable for sold/flux-cored wire
