  • Page 18 PROMTS 252i • Fill the crater at the end of the weld to avoid a crack. One way to do this is to dwell in the weld pool for a second at the end of the weld. STICK Welding Tips and Tricks (Also known as MMA-Manual Metal Arc or Shielded Metal Arc Welding-SMAW) Connect the Stick torch to the - terminal and Torch Control receptacles.

Adjust the amperage according to the recommendations of the electrode (welding rod) manufacturer for the type and size of the electrode used.

  • Page 21 PROMTS 252i washing of the weld bead into the sides or “toes” of the weld is important. Keep the welding electrode or the TIG tungsten and welding arc within the weld joint to prevent overlap. Pausing on the sides of the welds to wait for the sides to fill reduces the chance of undercutting, even if the current is a little too high.
