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.

Main Features

Presetting Function

Stepless adjustable welding current and welding time, and digital display ensures different level user and different time to weld in the same welding conditions, accordingly guarantee welding high quality and pass rate.

Accurately Control Welding Time

The welding time can be controlled to 0.01~2.80s, welding heat is controlled accurately and reliably, can operate with the same parameter repeatedly.

Automatic Compensate Function

The special circuit to automatically compensate welding current regardless the fluctuating input voltage.

Extremely High Dependability

The main circuit is controlled with no contact terminal because the thyristor rectified, high duty cycle designed.

Reducing Welding Spatter

Adjustable drop damping of welding torch reduces the spatter and improve the welding reliability.

Available Automatic/ Manual Control

The selecting function is suitable for penetrating through the multi-layer plates to weld.
