Momentary/arc-start switch for HTP America® Invertig 221 AC/DC TIG welders. Fits air-cooled and water-cooled torches and easily attached to your TIG torch handle with Velcro straps.
Available in 12.5' and 25' lengths.
You can use the arc start switch with 2T or 4T. In 2T-you set the machine to the amperage you want and then press the button to start arc. It will slope up to the amperage you have set. You must hold the button down while welding-when you let go of the button it will slope down and stop welding.
In 4T-you press the button and it starts. When you let go it will slope up to the adjusted amperage then when you press the button the 2nd time press and hold it slopes down to the final current. Release the button and the arc extinguishes and it goes into post flow.
You can also use it in the tig reset mode. The Tig Reset mode allows you to switch between 2 pre-programmed welding amperages. For example, if you have your peak current set to 100 amps and you have your reset current set to 75%, then you will be able to toggle between 100 amps and 75 amps.
