    Mig or Tig for auto stuff

    I am a total car guy but a complete welder newbie.

    I am ready to buy a welder and my wifes uncle (pro welder by trade) says get a tig but he is not a car guy.

    I always see guys using mig for most car stuff like body panels unless its trick stuff like intakes.

    The Tig I was looking at is the dyn 200dx. I want something that is not gonna hold me back for the garage mech in me.

    Mig would be a 250 or something that size.


    Can I do anything auto related with tig? I dont mind if its gonna take a little longer if I can do it and it be as strong.

    Also could you just use the stick for body panels or is that totally different from mig as an end result.

    Thanks

    I then found a mm210 local with tank, and 3035 spool gun and 6 al rolls for 1100 so I bought it too. It had never even had a steel roll hooked up to it. They used it for a couple al jobs and thats it.

    Thanks for all the replies.
    Game, set, match! Nice setup.

    i have not tried the Dyn200 yet , but a friend has a MM210 and i got a chance to play with it, and wow!! great MIG. i was doing some 22gage floor panels with it. and it was great. get a tank of C-25 and a a big roll of .030 wire. the MM210 is tuned for the .030 and will get about any job done in ..030 with best results. he tried some .025 and just did not like it. gave me the hole 11# roll and went back to .030 hey if it works don't fix it.

    as for the Dyn200, order some 2% lanthanated tungsten. it will work great for AC and DC applications and holds its point best of any i have tried. i don't have the Dyn200 but do have a similar inverter with almost the same functions. (TA-185) the most popular tung. are lanthanated 1.5% & 2% and 2% cerated.remember you have an inverter now, no pure tungsten, no balling.

    happy welding, be shore to show us the stuff ya do.

    you have it made. thats an excellent set, should cover all your needs. i suspect you will find the MM210 getting the most use. both top quality welders.
    congrats on the new toys , enjoy.

Granted it was an old vehicle so it was heavy gauge but it worked. Never cracked & warpage was minimal. I packed the back side of the panel with wet rags & went slow with spot welds.

    I too have welded body panes with stick (because i had to), and as you say they were probably thicker gauge than what you would see today. Turned the heat way down and used 3/32 7018 downhand. Travel is really fast but it will work.

    In my opinion any auto work is better suited to mig than tig.. especially if you are inexperienced. Tig requires a lot more skill and practise than mig.

    One non weld cert car nut's opinions. I weld thin and even very thin* sheet all the time with the little MIG and big stuff with the big MIG. MIG is a good place to start with welding. If you get further into welding owning the MIG will not be regreted if you purchase a TIG. I knock out a lot with a punny little Miller 135 120V machine using .023 wire but go to the 251 for the heavy stuff. I save the TIG for when looks matter or the metal dictates. Last night I Migged up a foot well framework for a throttle cable using the MM135. Added a base plate in the footwell that was welded up beforhand with the MM251 and then made a curved Al plate with a spring holder for the motor end of the cable using the Sync 250. (The spring takes up any stress from overloading the cable but still lets me ajust the system for full 100% wide open throttle) All the above could have been done with the MM135 if preped the thicker steel work right and used steel rather than Al on the throttle guide.



    Workshop work on cars with no need to take the machine on the road. 220V MIG to start new or used. Get a Tig later by watching for a great deal. Learn some welding, Learn about the machines and methods. Bide you time, keep an eye out and pounce on a great deal on the (used) machine you want. They come up for sale and I expect with the market like it is more now than ever. Miller machines are robust for the most part and are straight foward in function. Used does not mean used up.

    For very thin sheet I made a gas and feed control. It lets me pulse spot the little MIG and with care and a little skill weld metal that is thinner than the spec inside the door.

    There are MIG machines set up to braze metal as well. shoots wire but does not melt the base metals only the wire. Nice fast low(er) heat flat panel joints with little finishing.

MIG is faster on mild steel and works very well for panel replacement (LOTS of tack welds). There's no way in Hades that you're going to do body panels with stick. The Dynasty will do anything that needs to be done with stick electrodes, but you can't; because it's really, really hard.

    One thing that you have NO clue. Welding is VERY difficult. You don't just buy ANY welder and start welding. I'm in my third welding class, basic MIG sheet metal, O/A and TIG this time; and I embarrass myself EVERY night ; I started O/A welding in 1977. Welding is a VERY difficult art form, learned over years of experience.

    You need both, a TIG and a high quality MIG. I'd start with the TIG.

    Edit: TIG will do very well on suspension stuff, IF YOU HIRE SOMEONE ELSE TO DO IT.

    Good luck Rookie, maintain your sense of humor; because you're going to need it.

    Welcome to the incredibly complex world of Welding.
    The picture is the Dodge Assembly line building Carryalls. The body was stick welded. The welder in the picture is welding on 16ga interior panels with stick. I dont share this ability nor care to try stick welding 16 ga, but it was done on the lines back then. When I rebuilt my Carryall, you could see all the welds had been ground smooth with NO Lead or filler. I cheated and used my Miller 250X with .023 wire. I cant imagine the skill level needed to weld 16ga with stick.

    I really like taps better. On my SP, B, C, D, thin, medium and thick, use 3 settings on the machine, very easy. My 255 has infinate, big pain in the rear.

    Although you have had alot of good advise, I will throw in my .02. Most Auto makers recommend MIG for HSS Body panels and frame work. Mig is fairly easy to learn, I would recommend practicing for at least 2-3 months on sheet metal and steel from 1/8" to 3/8" thick before embarking on an auto project. Work on out of position welds as well as most of the time you will not be working on a flat surface and probably will be standing on your head while you do it. Oh, and most important, learn how to tell the difference between 20, 18, 16, and 14 gauge materials, it will save you a world of hurt once you put wire to metal.

    [QUOTE=superdave99gt;158573]could you or someone else clarify this. I dont understand why the 252 or 180 is better. I am a newb remember. lol


    Also, I found a mm210 that looks brand new (he says 3yrs old ) with a 3035 spool gun and small gas cyl for 1300. Is that a good deal or not or should I pass and try to find a 252.[/Q : The Difference between Tapped Control & Continuos is with Tapped you have specific settings, with Continuos you have Infinite Control or Settings; Norm
