Thyristor Drawn Arc Stud Welder
Thyristor drawn arc stud welder is a classical machine in Sino Stone, which was designed for high-speed welding stud or similar bolt on base plate, now it is the 5th generation product and it can work 24 hours continuously after specially designed main power source with compact size and light weight, it is more stable than inverter welder.
Thyristor welder is widely used in the steel construction building, bridge, boiler, shipbuilding, locomotive, smelting engineering, electric power build, chemical industry, oil field build, etc.
There are three types machine for different diameter of shear connector: SST-1600-5, SST-2500-5, SST-3150-5.
