    Miller is top notch for all you welding needs. Can't wait to our new all in one shop unit on the ship.

    I have a Hobart 250. If it wasn't so darn cheap, I had my eye on the Syncrowave 250. Great machine. I guess you would call it the standard by which all others are judged.

    Sit Down, take a look at it, take it apart, and FIX it!

    Re: TIG Welders

    The 250 is a great machine when it's for commercial use, most fab shops would have this or equivalent. Honestly I would reccomend the Hobart machines for personal use. It's not the machine that makes the weld better. It's the man using it. The torch is very important, it's probably more important to pay attention to the torch and the accesories used then the machine itself.

    Re: TIG Welders

    Thanks for the responses. Yeah I've heard great things about Miller brand welders in the past. Also heard good things about Lincoln. I finally got a 220V 50A outlet plug in my garage this year so it's time to start saving up for a good welder. I've welded in the past but not nearly enough to say I can do it worth a shit. Gonna start by welding scrap pieces together for hours on end.

    Are the foot control operated units the easiest to work with?

    It's so much easier to suggest solutions when you don't know too much about the problem.

    Jordan, you would be best with a Miller Diversion 165 imo... We use a 250DX luquid cooled here but it's almost too difficult to setup for basic daily tasks, and it's surely too much for your average diy'er (esp for the price!).

    Re: TIG Welders

    Well my Audi tech buddy Forest picked up a brand new Miller syncrowave 250 DX a couple weeks ago. Gonna be in my garage for awhile though. Started just doing some basic welds with aluminum and steel. Steel is much harder to tig well IMO. This machine is a beast to say the least. We were needing to weld 1/2" aluminum to make a motor plate and the breaker kept kicking. It's only a 50A breaker but the machine says that 50A is okay. Guess not for that application. Gonna have to get a 100A breaker installed ASAP.

    I still need tons of practice.

    The machine has the water cooler built in. It only kicks on when things get pretty hot. We ended up putting in an 80A breaker cause 100A would have been a PITA for what we were working with. Have not popped the 80A breaker yet and did some major welding on 1/2" aluminum plate!

    Did I mention that I still can't weld for shit! LOL. My buddy Forest is quite good at it though...

    I have to agree. (Not as claiming to be an audi guru, by any stretch), but coming from the military aircraft fabrication side, the equipment that we had was less than great most of the time. This left us with the need to get as good as we could with the gear that was around, and the work that we put out turned out looking just as good as the stuff made in country. Everything from tilt of the hand, to patience helped.

    That takes extra time and time if of the essence. Have not popped the 80A breaker yet with 1/2" AL... so no need to preheat anything.

    Thanks for the heads up though.

    Preheating is advised at times to prevent element breakdown of the metal being welded. Anything beyond 1/8" I'll usually preheat in Al. Holding your torch in the weld path too long to make a good puddle can make for a bad weld also.

    Heres some stuff that was done with a 12 yr old lincoln of mine. No special features.

    So how about a TIG welder for those of us on a budget? My old Miller stuff all got stolen, but I am finally ready to start doing some stuff and I need something for mild home use (manifolds, etc). Any suggestions? Its been so many years since I've done any welding that I am fully out of the loop. I remember how much nicer it was to use a nice torch, but Ive also never used a crappy machine either.

    hobart is probably fine. lincoln and miller are a bit more. again its the man not the machine.

    I'm rolling the dice and going to try a Chinese made welder from Everlast. Apparently these things are selling like hotcakes since Jody Collier (of weldingtipsandtricks.com) started posting videos using 250EX model. If my livelyhood depended on it, I'd spring for a Miller or something else. Since I sit at a desk writing software for a living and this is just a hobby, I can afford to be down for a week or two if the thing breaks.

    I'm starting off with the harbor freight unit i bought for $150 on ebay. I have no shame. haha it actually welds pretty decent. I'll step up to a better welder soon. The cost of everything else was the catch. Bottle of argon was $260, wiring, consumables, flowmeter, helmet, protective gear, etc all add up.

    Nothing wrong with that if you just need DC for steel and not a ton of amperage. I've heard they do pretty good for the money. You can always sell & upgrade later with no guilt or regret.

    So far so good with my Everlast unit. Had some shipping damage and few kinks to work out but it's all good now. Upgraded from the crappy factory supplied torch to a CK-200 with the Superflex cables and a gas-saver lens too. MUCH better!

    exactly. seems to work ok for me for little projects. The skeleton of all the other equipment is there. The wiring and extension cables and NEMA plugs were $$. probably have $200 into the extension cable to my welder 25ft. I'm still learning this craft though. Here is a pic, I think i needed a little more heat into this weld. I'm still only on my first bottle of argon so I def need more practice with my feed hand. I'm using about 90 amps, 3/32" grey tungsten, about 10 cfm of argon on a #4 cup. some feedback would be nice.

    I am a aerospace certified tig welder and do custom fabrication work for race cars. pre heat is the best idea for aluminum also if your tripping the breaker all the time look into inverters we use them all the time in racing due to their portability more technology and more capabilities crammed into a smaller package they run off of 110 or 220 on less amperage ie wont trip breaker well welding with high amperage. also Lincoln electric has an inverter where you can set what the starting amperage of your pedal so it dosent start at 0 amps. i live in cleveland where lincoln electrics world headquarters is so pretty much every shop around here uses lincolons

    Miller Dynasty 200DX.... Makes me cringe seeing them go now on ebay for 3k all day long compared to that of what I purchased it for when it was first released, however absolutely worth its weight in gold for your garage shop custom needs. Gives the user the ability to do anything from quick touch ups to that meticulously fine tuned show quality bead we all desire. 110/220 option as well makes it nice to throw in the trunk and run to a friends to run a bead or 10.... Can't go wrong with it...

    The real question is thickness and material and a inverter (space) or a old solid state like the synchro wave or my power hungry lincoln 375amper
    I like the solid states i mean there is too much to go wrong on the new Chinese circuit boards on the new stuff. That being said my old lincoln is about 700lbs and guess what no one asks to borrow it ;)

    I've worked at two different shops with a dynasty rig (both 350's)


    Both shops have issues with reliability. Boards like to go on them.


    I'm looking at a thermal arc rig for at home, as the shop i'm at now doesn't have any welders for me to abuse. A friend's got one, puts down good beads for the money in alum. (has HF/pulse)
