Product Details
Inverter Semi-Automatic Gas-Shielded Welding Machine
1. Adopt waveform control technology to improve appearance of weld
and reduce splash.
2. Use digital display to preset welding parameter accurately.
3. Current and voltage can continuous adjust in wide rage.
4. Soft switch technology makes the machine high efficiently and
high reliably.
5. Passive power factor calibration (PPFC) technology has high
power factor.
6. Arc-starting with slow wire feeding will be easy to starting arc
and increase success rate.
7. Wipe off small curve loop when ending arc.
8. Small welding deformation, good welding point
