-gas (argon) should be used set at 15psi
-welding machine should be set to DC- (direct curent negative). set heat to 50-55amps when using 3/32 tungsten and 3/32 filler rod (mild or stainless).
-sharpen tungsten to a short point for preseving tungsten and alow a baby finger-nails length to petrude from tig gun.
-start your arc with the tip of tungsten aprox 2mm from steel workpiece. if it sticks relese foot pedal break off by tipping sideways resharpen if needed.
-when a successful arc is achieved make sure tig gun is staight up and down and side to side when using the weaving method weaving side to side slightly larger than the filler. when using the quicker (drag method) tilt gun on aprox 75 degree angle with the top of the gun pointing away from the direction you're welding (without weaving) once again the filler weld pool should be slightly bigger than the filler rod. filler rod best held at 45 degree angle or less. prctice and a steady hand have patience.
