  • Tig Weld Starting Point

    Learning to tig weld and am just wondering if there is any kind of starting point for amount of amps to use for different thicknesses for metal. My stick welder is also a tig welder but does not have a chart for starting points. Any help? Thanks guys

    You know you're a welder when... You miss your court date because you stood outside the courthouse looking at the welds on the handrails.

    I'm certainly no TIG expert but 1 amp per thousandth inch thickness (steel) seems to be the rule of thumb.

      Yup.... +1 on the "1 amp per thousandth inch thickness"

      this guidebook should help too

        This is definitely not the best plan, but it's what I did when I started...I set the machine to max and use the foot pedal to control my amps. Then I would run practice beads and cut the amperage back about five amps each pass until it sucked. Then I heard that 1 amp per .001" thing. It's a pretty good guide. <br />

        A couple other tips....get comfortable and stop to reposition when you're not comfy any more. Keep the torch angle in the forefront of your thoughts; it's real easy to forget to keep the correct angle. Keep a short arc. Keep the hot end of the rod shield. If the rod feels like it's sticking in the puddle when you dab, you're probably using too big of a rod. Don't be stubborn; when you stick the tungsten and get it all nasty, stop and regrind it. And finally, just have some fun with it. You won't be welding on the space shuttle anytime soon, so let the screw ups roll off your back like water off a duck, or however that saying get my point.

          I tell people welding is like handwriting, the more you do it the better it gets
