I have been welding for years and taught my son to weld also, I had a Lincolon 225 that I bought at a pawn shop around 25 years ago and it still works but my son talked me into going with a Mig because i guess he got sick of me calling him every time I needed thin stuff welded, he has a Miller Mig and uses a Hobart at work, I did research on welders for about a year and found what I thought was the best, It is a HTP Mig 160, I had never used a mig before I got this one, always had my son do it with his, well I got mine, a tank of gas and went to town with it, you would think I had been mig welding all my life from the beads it lays down, my son came over and he did some heavy welding on a car dolly with it and said it made his Miller seem like a peice of junk and it is a lot better than the Hobart he uses too, you can weld with or without gas with it, just when you use flux cored wire you have to reverse the polarity on it
It has a good duty cycle too,20% at 160amps and 100% @78 amps, I have done some long and heavy welding with it and have yet to have it shut down on me and that's welding 1/4" and 5/16th" metal, I also got the kit for it so I cane weld aluminum, you just have to go to 100% argon gas and change to a teflon liner, it's a bit more tricky than welding steel
But if you want a fine welder HTP is the way to go, the folks I bought it from don't come any nicer either, I bet I emailed the head salesman 30 time asking questions before I finally bought it and he never once acted like he was getting sick of me
They have them in all price ranges too, I paid around $1100.00 for mine but that inclueds the tank and the aluminum welding kit, plus I went ahead and got a box of extra tips and sheilds for it, if anyone wants to check them out and are thinking of buying a welder and if it is allowed i will be happy to pass on their email address, like I said , it is without a dout the best we have ever came across, I just love mine, I used it for a couple of hours today building an air powered can smasher, fun fun
