. Have the consummate protect circuit and malfunction display function, safe is reliable and is advantage the malfunction search.

. Arose the arc to be easy, the electric arc stable, few splash, the weld joint shape perfect.

.Cubage small, the weight is light, highly effective and save energy, high load continues rate, the arc weld rectifier no noise.     

Structure reasonable, the layout succinct, convenient for repair.

.Adopt VMOS high frequency inversion technology, can guarantee the welding voltage under the electric net wave and arc weld length change situation high degree stable, electric arc has strong selves adjust ability, the welding course stable.

.Adopt the special control method, output current stable, resistance electric net voltage and welding environment disturb.

.Adopt the strong impulse arose the arc, arose arc high succeed rate.

When returning the arc, has dispel the ball function.
