    MM140 or MM180

    im ab out to buy a 1963 corvair suspecting it will need plenty of restoring I was thinking abuot up gradeing from my pep boys welder. would it be woth the extra money to buy the MM180 or would I be going a bit over board and should stick with MM140.

    I agree with everyone else, go with the 180 if you have the extra funds. Spending a little more on the bigger unit will pay for itself shortly if you use it any at all. In the welding world, I'm a firm believer that bigger is better, because you can always turn the heat down as needed, but you can only go up so high before you run out of amps.

    If you have 220v service, there is NO WAY I'd go with the MM140. Almost 100 years ago (or there abouts), I wanted to upgrade from my Oxy/Acet. So I bought a Syncrowave 250. And I've NEVER been sorry. My next purchase will be a Miller 220v MIG (or a Miller 375 plasma cutter). Decisions, decisions.

    If you're under 50 or 60 or 70; buy UP. You'll get to cuss bad tools for the rest of your life.

    well you can R.I.P. TacMig because I wouldn't dare to dream of welding the most crutial part of the car,the frame(I don't consider my self a seasond anything). And you are right that cars where built a little thicker in the good old old days. but I agree with sundown, you can't add amps to your machine but you can reduce what you have.

    2tay,

    I'd recommend the larger unit. You can always dial a larger unit down, but you can't use amps you didn't buy.

    You may also want to look at the Hobart HH210 (a 210A unit)which has received rave reviews and is priced not much more than the MM180.

    Just my .02

    Hello..

    You will be much happier with the MM180 and its abilities over the MM140. While the MM140 is great, it lacks the huevos that may be required when working on your car. A 63 Corvair will be equipped with a more generous and more robust steel than later models and you want to make sure your welds are sound. Remember one thing however, if your frame requires welding even the MM180 may be a tad light but unless you are a seasoned pro, I don't recommend heating your frame in any way and leave that part for a pro.

    Good luck,

    TacMig

    Pep Boys have a welder with their name on it ?

    If it was me, I would go with the MM180, that is if you can afford the little extra. There may be a day down the road where you will kick yourself in the butt for not going one better. Just my 2 cents
