TIG Welding: Adjusting Controls on Your Welder

Kevin Caron: I had a request the other day off of YouTube. The gentleman wanted to know: How do you regulate the TIG welder? How do you regulate the machine? What are all the knobs, buttons and dials for?

This is my Miller Sine Wave. It's a TIG welder and it's also a stick welder, or an arc welder.

You simply turn it on and let it boot up; let it wake itself up. The main control on this is the amperage knob; you can see right here it's sitting at 7 amps right now. You would turn that up to, say, 15 amps if you were going to be welding something like real thin gauge aluminum, or thin gauge steel, such as a 20-gauge, 22-, 24-gauge. That would almost be like aluminum foil - really thin stuff.

Turn that amperage, way down. You can boost it up to, say, 35 amps for things like 16-gauge steel, eighth-inch plate. You might want to go a little higher, say, up to about 45 amps for something like eighth-inch plate.

If you were going to get into quarter-inch, let's turn it up to about 65, 70 amps. You'll get a little more heat out of it; a little more penetration. Now, if you're going to get really crazy, and you think you're going to get into some one-inch plate, you could turn it up to 150, 160 amps.

But you really wouldn't want to weld one-inch plate with a TIG welder. That's when you would shut your machine off, and switch the knob over to stick welding, set up your stick welder, and then turn it back on. And you're ready to go.

Adjust your voltage right: a hundred and . . . remember, now, I am not a certified welder. I am self-trained in all of this. So, the numbers that I'm spouting, I'm sure some of you won't agree with, but they work for me. But for stick welding, go to 100 amps, 120 amps, 130 amps, for something like one-inch plate.

That's all there is, really.

It does have a pulse function for the stick; for the TIG welder. The pulse function is really kind of fun to play with, and it's just like it says: It makes the arc pulse, so if you're welding on thinner materials, you get a spike in your amperage, you weld, and then all of a sudden, it drops off so you don't burn through. It allows you to weld on thinner materials. It makes your weld look a little better. It's a nice function.

That's about it. Now you've just got to practice - lots and lots of practice.

Hope that helps. See you next time.
