China IKING igbt inverter type drawn arc stud welder are mainly applied to the installation of stud fusion welding in construction of steel structure, bridge and railway etc . with functions of weld time preset, weld parameter preset and digital display etc. The precision preset time can reach to 0.01 second, and welding preset current can reach to 1ampere, which improve welding reliability and stability and can be operated easily.
The main power of the welding machine is designed in a compact size and lightweight can work 24 hours continuously. With the design of anti-misoperation, it can prevent repeat welding onto the same point. The welder also has functions of short-circuit protection and circuit-breaker protections, which can protect the circuit control board well, and the welder can be started smoothly after trouble-shooting. With all protections above, the failure rate of the welder is low, and it can prolong the life-span of welding machine.
Light weight, simple maintenance, stable and reliable welding quality, energy saving and environmental protection.
Trial industry: steel structure, shipbuilding, chemical, construction, metallurgy, automotive, bridge, boiler, chassis and so on.
