Technical Advantages
- The output characteristic closely resemble those of a AC welder,offering excellent arc stiffness and improved droplet transfer during welding.
- Excellent for overhead,vertical and 360°all-position welding with electrode 427/506/507.
- Thrust current continuously from 0 to 100A, significantly improving deposition rates for alkaline electrode.
- 90A root welding, free arc direction control,even pesentration, and reduced operator requirement.
- High duty cycle delivering high-current long-duration and ultra-reliable performance even in 40°C high-temperature environment.
