Technical Advantages
- One-click electrode selection mode.
- Auto voltage detection and conversion.
- Welding current:precise to 1 amp adjustment.
- Intelligent fan control: Auto fan off after 6min idle.
- VRD low-voltage technology ensures the safety and reliability.
- Thrust current: Maintains arc stability even in 100m output cables.
- 3-second short circuit protection: auto power cutoff if no arc forms
- Start current:continuously variable,providing markedly enhanced arc initiation.
- Power-saving design with auto shutoff (5s no-arc) for safe and reliable operation.
