Like the title says, what is a Miller Matic 35 MIG welder worth? Including a full tank of 25/75 CO2/Argon, regulator, hoses, etc. Tank is about 4 1/2 feet tall but I don't know how many cu ft that is. Is there anything on one of these that I should watch out for? But I have very little experience with MIG and non with this model so I'm operating blind here!
Good welder, used to own one. Welded a lot of chrome moly tubing with that welder.
Provided that you can get it for a good price $300-350ish, it's worth that.
Of problem is going to be the air bottle. Most large bottles over 80 cu ft aren't sold just rented, so your chances of getting it refilled are slim. If the shop is willing to take the bottle on exchange, life gets better.
I own all of my bottles, two 80 cu ft O2 bottles, one 40 cu ft acetylene, and two 80 cu ft CO/Argon bottles. With the frequency that I use them, it paid for me to own verses rent bottles even though I get hit every ten years of so for a hydro test.
Last time I checked at my weld supply house the rental on a bottle was $6.00 per month.
