Basic Instructions for learning how to tig weld steel...welding a bead on plate

  • Set your TIG machine polarity to DCEN. But first make sure your tig torch is plugged in the correct port with the minus sign - . 
  • for 1/4" (6mm) thick steel and thinner use a 3/32" (2.4mm) tungsten that has been sharpened to a 30 degree taper. You can sharpen tungsten a number of ways but either a hand grinder or bench grinder is fine for now.
  • a #8 tig cup with 20cfh of argon gas works for most steel applications.
  • extend the sharp tungsten tip to about 3/8" from the end of the #8 tig cup.
  • turn machine on and tap foot pedal, torch amp control, or torch switch to get argon flowing and adjust flow rate to around 20cfh with the #8 cup.  ( 2-3 cfh per cup size if using a different size cup)
  • put your tig gloves on, get comfortable and prop your torch hand far enough from the weld to avoid getting burned
  • with tip of tungsten only 1/8" off metal, press pedal or torch trigger to establish an arc.
  • increase amps to get a weld puddle
  • add filler wire and move along the joint to create the weld.

I hope you got some good instructions here on learning how to tig weld steel.
