TIPS FOR TIG WELDING ON STAINLESS STEEL

1. Proper fit up ：Proper fit up ensures that only the required amount of filler metal is used. 

2. Filler metal ：The thicker the rod or wire the more heat is required to melt it.

3. Electrode size ：Common tungsten electrode sizes range from 3/32 to 1-1/4 of an inch

4. Electrode geometry ：A taper of no more than 2.5 times the electrode diameter creates a focused arc capable of producing deep, thin beads, and a narrow heat-affected zone

5. Fingertip and foot control ：A foot control allows for a more precise control of amperage and doesn’t interfere with your torch hand.

6. Puddle size ：The weld puddle should be the thickness of the base metal.

7. Gas flow and travel speed ：Keep the gas flowing and directed at the puddle until the orange color fades.

8. Polarity and pulsing ：Use pulsed gas tungsten arc welding with a direct current electrode negative current
