Duarable 60% duty cycle Inverter igbt 150 Arc welding machines for acid soldering bar
1. Smart inner structer and duarable life;
2. Easy arc strike and easy maintain;
3.60% duty cycle.

Function and Features:

Advanced single tube IGBT full-bridge inversion technology is adopted with frequency of 20KHZ, and reliable PWM current control technology is adopted, featured with constant current, stable welding current and excellent and accurate control; Internally self-adaptable arc striking function increases success rate of arc striking; Mighty thrust current adjustment function with internally self-adaptable system assures welding forming, facilitates welding depth adjustment to make the welding power supply more suitable to the welding technology; deep welding bath, good-looking form and high welding quality; The internal structure has the function against dust, moisture and corrosiveness and improve reliability to the machine under severe environment. Applicable for acid soldering bar, alkali soldering bar, stainless steel soldering bar, casting steel soldering bar, thermal resistance soldering bar and ect., and low-carbon steel, intermediate carbon steel, alloy steel and etc. High load continuity, and continuous welding; Screen voltage compensation, and strong capability against fluctuation of the electric grid.
