A bit of an intro:
So I recently bought one of those scratch start TIG torches that plug into an arc welder with a dinse connection. The arc welder I'm using as a power source is an old 250amp ac/dc Busybee. I had to make a new connector for it, as the arc welder uses the old Miller style taper connections.
Got the connector made up, hooked up to a fresh argon tank, set welder to 40 amps, regulator set at 20cfh, using lanthanated tungsten sharpened vertically to a point. Material I'm learning on is 16g 304 stainless flat stock I had on hand, just practicing stringer passes and a few simple fusion welds. I prep the stainless with one of those flappy sanding disks on a drill.
Starting the arc is no problem. Ending the arc is where I need help. I try whipping the torch and bringing it back quick to keep the weld submerged in argon, but still end up with a small crater at the tail. My welds aren't pretty yet, but I want to learn how to end my weld as clean as possible before perfecting my beads. Any help? Or should I have bought a new welder that has HF?
