HERO TECH AC Art Welder is an arc welding power source manually operated by a single person. This type of welding machine is made up of a moving-iron type arc welding transformer. The welder uses the trapezoid magnetic core as the magnetism shunt, with the result of a wider regulation range for the current. With the high grade insulation material as the cushion coat of the winding turn-to-turn insulation, the welding machine has the feature of quick radiation, high efficiency and longer operating life. It also features with compact structure ~ reasonable design ~ low noise and convenient remotion etc. It is available for long time work on static or moveable site. The power supply is high O.C.V. It can get satisfied of welding with use electrode E7018.
