Been thinking of buying a tig for a while , I've been watching the reviews on the AHP tig for a while and for the most part reviews have been good with a few DOA's here and there . Anyone have one of these or got rid of one they didn't like . I'm leaning toward the Lincoln squarewave 200 but for as much as I'll use it ( well actually the boys want one and they are telling me to buy the AHP ) not sure if I should spend the xtra , it's double the price at $1400 . And has a lot less features . Used machines are hard to find and they are mostly the old transformer units ( last forever but use big power and space ) . Thanks Richard

Eastwood has a deal on a TIG and plasma cutter set. My buddy bought the set and he's pretty happy with it.

I have an AHP and for the little I have used it, It works.
I tested the tig and stick function and all was good. Only on 120vac. Did not have 220 at the time. When I first pulled it out of the box i was surprised that it was a half descent put together machine. I have a lot of work lined up for it on my car parts that I want to do,when I get time. |

I used to be a professional welder, welded stainless steel for food processing and steel for all sorts of uses, including high & low pressure steam, ammonia refrigeration. I could stand on a ladder, hold onto something with one hand for support and weld with the other. I could also weld equally as well with my "other" hand as with my dominant hand. I used stick, tig, wire, and gas welded and brazed, silver soldered, you name it. I was certified for several different procedures, including pipe and structural.
Where am I going with all this you say, I read the reviews for the AHP tig/stick machine, and I'm impressed, especially because I am a staunch Lincoln guy. For $800, if it dies at the end of the three year warranty, you have no loss..... |

I have a Lincoln Squarewave 255 Tig Welder with Water Cooled Torch and convertible to Stick, it has seen a lot of hard service doing Aluminum and Stainless Steel flawlessly, but it does take up alot of space and I think is way overkill for anything you would run into in the Automotive World. The only problem it ever had was the "touch" pad to adjust the current and modes. The main reason I bought it was to do very thin Aluminum and S/S and you can dial the current down so low. If you are keeping in the hobbyist world, I would go with Armand (White70JavelinSST), low investment advise. Just keep an eye on the consumables/parts prices, some companies like to gouge big time on the air cooled torches and make it very difficult to swap to a "generic" replacement. Used machines if you don't know the seller can be a real gamble too.

Thanks for all the responses , I'm mostly hobby but one son took metal fab so might be using it a bit ( just got out of school so we aren't sure where he's going yet ) . I know you can buy either and if they die your in the same boat but half the money with the AHP . The advantage to the new Lincoln is its small compared to the ahp which makes more sense with the 110/220 .

You don't need a TIG welding machine, just a TIG torch (with gas control valve on torch) and gas bottle with regulator assembly. Clip the torch electrode end to the rod holder, ground as normal, connect torch to regulator on bottle.
TIG can be used AC or DC. AC is typically used on aluminum because the constant polarity switch keeps the weld clean of oxides. AC doesn't penetrate as much as DC. DC straight polarity (electrode positive, ground negative) penetrates the most. For sheet metal or other thin materials reverse the cables with DC -- negative on torch, positive on ground. AC is sort of between the two DC configurations. You can weld anything with AC, just doesn't penetrate as much as DC straight at the same heat, but it's enough for even heavy welding on 1/4"-1/2" thick material, just requires more amps for the same penetration as DC straight. So if you have an AC stick welder you can get a torch and gas bottle setup and start TIG welding on the cheap. |

I really wouldn't want to learn how to tig weld aluminium without frequency control. It's possible, but learning on a machine that was intended for the application first would be easier. The DC/inverter arc conversion setups work incredibly well though for mild steel and stainless.
