Stahlwerk AC/DC TIG 200 ST – Part Number 6918

2T/4T (TIG) – determines the control of the operating mode and offers extended control over the current flow. In 2T mode, high-frequency (HF) ignition remains active until the button on the torch is released. In 4T mode, the arc is ignited after pressing and releasing the button once. After pressing and releasing the button again, ignition is terminated. Some functions, such as current reduction, are only possible in 4T mode.

Current reduction – prevents the formation of blowholes (end craters) at the end of the weld seam.

Gas pre- and post-run (TIG) – protects the tungsten electrode from excessive wear and protects the weld seam from oxidation. The parameters can be set individually and separately. They specify how long gas should flow before and after ignition.
