that size welder is for sheet metal also with a short duty cycle like 25minutes out of an hour if you plan on doing 3/16 and thicker i,d get the 250 amp machine from miller. that way you can do it all and not over heat that small machine. but you know what your useing it for better than me. i,ll gaurantee you you,ll want to weld thicker materials though. also if you,d get pure argon you can weld mild steel , stainless, and even aluminum with your wire welder ! dont do the flux core route ! 75% argon 25 % co2 is for carbon steel only. dont limit yourself as much as possible. a miller machine will last you a lifetime if you take care of it. trying to weld thicker material will cook the inside of the machine. i,ve had my miller vintage ( 250 amp ) for years with no problems and do up to 1/2" with it. also a tip when you buy your machine its your best time to buy comsumeables ( cups, tips wire feed rollers in different sizes-.023, .035, .045.) get a supply of these in with the deal or you,ll pay retail when you need them. also look aroung your local trade papers and pickup a good used tank with a bill of sale, you,ll save alot of money and that will buy your consumeables. you can get a oxygen, argon, co2 , etc bottle and they can change the valve & lable to make it the tank of your choice. cant do it with accetalyne though its all by its self. just trying to help. been doin this for 35 years.
