I been practicing my tig and the key holes gets to big too fast is it because of the amp on the welder need to be turn down help thanks.

Very likely or rod not being dipped fast enough. If you give us more info like prep angles, gaps, amps and wire thickness we might be able to give you better advice too. Maybe a pic as well.

If your talking pipe then your arc length is too long, your moving too slow, or your fit up isn't even. Could be any combination of these but there the most common. How are you prepping the fit up. I.e. Gap / no gap? Land / no land?

[Shaun1975]

No landing at all and my gap 1/8 I'm more comfortable with 1/8 gap and 1/8 rod unless I'm wrong ?

Try knife edge, no gap, and a 3/32. Set your stick out so that when your cup is touching the pipe the end of your tungsten is just about to touch the top of your filler rod. Just lay wire and walk the cup.
