I know I'm a little late to this party, but I have owned my original 240 century welder(Lincoln clone) from HF for over 20 years... it's welded many floor pans, roll bars, bumpers, trailers, and everything in-between. Yes its gas capable and only thing I've replace has been the control switch and recently a new lead. My son-in-law has a roofing business and I’ve started maintaining his large trailers, so I did a little research and settled on a new Vulcan 220 multi-purpose. And so far, welding ¼ inch plate has been a breeze. Now to see if it holds up like the Century!!
