Technical Advantages
- IGBT full-bridge inverter technology with independent property rights, double closed-loop current control. rapid response to arc length changes, continuous arc, no arcing break or arcing blow.
- High load duration, equipped with arc ignition current and thrust current adjustment function.
- The output characteristics are similar to those of an AC welder, and the arc stiffness is good, which improves the droplet transfer during welding.
- The arc starting current is continuously adjustable from 0-100A, which greatly improves the arc starting success rate.
- Excellent 427506507 electrode for overhead welding, vertical welding, and 360° omnidirectional welding. The thrust current is continuously adjustable from 0-100A, which obviously improves the welding cladding rate of the alkaline electrode.
- 90A bottom welding, free control of the arc direction, uniform penetration, and lower operating requirements for welders.
- Satisfy high-quality welding machine technology, high flaw detection qualification rate, high-efficiency for welding.
- 80% load continuity rate, high current, long time and high reliability work under a 40-degree high-temperature environment.
- Widely used in high-demand welding processes in chemical, pipeline, oil storage tank, power installation, teaching and training industries.
