TIG welding tips for dummies (me)

[miketweedie]

Hey gang. My fiancée knocked it out of the park this year and bought me a TIG welder for Christmas. I have "some" experience with TIG, but realistically I am starting from scratch. So, I'm wondering if anyone has a "tried and trusted" resource for TIG settings, tips, tricks etc.

My machine is dual voltage (110/220) which is important, because we still don't have 220 in the garage. I've been playing around with some scrap sheet metal, some 1/8" stock, etc. and trying to learn how all the different controls work. It has a pulse function, which is great, but I'm hoping to build a basic reference chart for when I need to use it.

If anyone has something like this, or knows a good website to get it from, I am all ears.

Thanks, and happy new year to you all.

Knowing the brand and model would help. There's some good pointers on Youtube, but most are brand/model specific.

If it happens to be a Primeweld machine, The Fabrication series on YouTube has a very in depth video on that machine. Even if it isn't a lot of machines are pretty universal as far as what controls do, they just might name them something different.

I am a full time Tig welder. Feel free to pm me if you need!!

Good call, Jim.

It is just a cheap Yeswelder 205P. It is DC only (I don't currently have any need to weld aluminum). Here is a LINK

Currently setup on 110V, pure argon, 3/32 tungsten and 1/16 ER70S2 filler.

Thanks DB, that is super generous of you.

Not a problem man! Welding is a huge passion of mine. I love helping people get into it!

That looks like an awesome and capable little machine! Has just about everything my Primeweld has just less knobs and no AC.

You're in the right track with the tungsten size and filler. I use 3/32 tungsten for everything up to about 270 amps, then I'll go to 1/8". Filler wire usually depends on material thickness. I tend to use 1/16 and 3/32 the most. Along with .45 sometimes.

The key to success is hood time and research!

Please keep us posted on how the machine is working out. I'm in the market for a cheap DC only TIG as well.

The title of this thread seems just fine for me...

About 2 years ago I scrapped my MIG and bought one of those very cheap inverter power supply MMA/TIG combination welders for £75. I went for one with the Lift TIG option. Just recently I have been playing with the beast in Lift TIG mode. The circuitry is very good for striking an ARC but unfortunately I am finding snapping the ARC off a little difficult and this gives me a small pinhole at the end of each weld. I saw on U-tube 2 videos where they made simple foot switches to interrupt the current to the torch. As you may expect they got a lot of arcing when switching of the TIG arc, but they were able to prevent pinhole formation. So I decided to make one with a couple of improvements to deal with the arcing during switching by stealing from the concept of ignition points and capacitors.

The lead on the Left plugs into the Negative on the welder and the Torch plugs into the socket at the Right. The switch is made from a domed piece of brass that pushes down into a matching counter sink, also made of brass. To prevent arcing at the switch when switching off the TIG arc a capacitor is placed across the contact points - Ignition concept. I used a large capacitor (63V 22,000 MFD electrolytic: Positioned in the white tubing on the Right) because I am switching a large current. At the instant the contacts start to open the current diverts to the capacitor and the voltage across the capacitor starts to rise resulting in the TIG arc being extinguished and no arcing at the switch contacts either. When the switch contacts are again closed the charged capacitor shorts and damages the switch contacts. To solve this I connected a heavy resistor (470 Ohm white ceramic thing on the Left) parallel with the capacitor to bleed off the capacitor charge between switching cycles.

I tested this final prototype today and have no switch contact arcing and I can terminate a bead without pinhole formation. For those wondering what this all has to do with the XS650, the foot switch uses a retired XS650 clutch spring...

This idea may be useful to those wishing to use their old MMA welders for scratch TIG. If you want more detailed photos just mail me.

Welding Tips and Tricks. There are videos on youtube and there is a forum where there are a lot of very knowledgeable people willing to help. Best help I've found for learning more about welding.
