What I should have said in my last post was that; in my old days; we always butt welded 2" and smaller, Schds 10 through 80, with an O/A torch. One pass around and no cleaning of welds. Only needed one grinder to bevel and clean up O/A cuts. Today O/A is becoming a lost art, that small pipe...

Good informative posts never die. My latest issue with transformer types is a Harbor Freight Chicago Electric 225A unit, current model 69029, that had a sticky adjustment. You can barely turn the adjustment screw. HF just discontinued making this unit last year and they are closing them out...

Brimfield has not responded on his projects and success with his black iron pipe which I am sure is just plain old mild steel pipe. Obviously, Gary has done miles of steel pipe like I have. No special cleaning is required. Schedule 20 and larger wall thickness, you need to bevel and multi...

Belated congratulations! Since getting older I am not on here as often. Fully retired now and staring at 88. Happy for you Jim on getting your Century working for you. You can operate on a 30-amp outlet but if you are using 5/32 at higher amps probably will trip the breaker. Thats why I...

Responding to the previous two posts: MIG and TIG gas shielding is tricky outdoors. Any stray air currents can blow away the shield gas. We always built an enclosure of some sort around the weld area for insurance. MIG flux core works same as SMAW on that score. Welding aluminum requires...

I will reiterate my previous; there is only one moving part in those old welders, the shunt plug that varies the amperage. There are no contacts or relays even in the AC/DC units. I seriously doubt any of the new solid state stuff will still be around in 50+ years. My MW welder is that old...

Jim, I have owned several of those welders in the past and had them apart. There is only the one moving part; the movable shunt that selects the output amps. If the exterior of the transformer core gets rusty that is what is causing the adjustment to be hard. You have to pull the shunt out...

OP-You may have found out by now that gas shielded MIG and TIG do not work well outdoors from air currents carrying your shield gas away. On material more than 1/4" takes multiple passes for the full penetration welds necessary for repair work. Weld material deposited on top of two pieces of...

Gary, missed this one back then. I doubt you can afford the freight even if it got to you, still have several. Guy was looking for an Argon cylinder. Traded an O2 at the LWS filled. Got my money back on that sale. The rest are gravy. I make more selling sets than the individual pieces...

I don't have MIG so use stick or O/A. I would never try to weld material as thin as the OP's with arc. I would use my Victor O/A with a 00 nozzle. Gaps are a big problem with sheet metal. A tight fit is best no matter what you use to weld it. I don't gap till approaching around 1/8" with...

Most of the old transformer type welders came with a 30A 240V short cord. They were not designed to be used for production work so worked fine on the 30A circuit. Guys like me changed them out to 50A for running longer distances and more production type work. I have had the 30A cords get...

Find the problem yet? Those little 10 CF tanks don't provide much flow. They are primarily used for light duty soldering, brazing, and welding. The flow it takes for cutting with the valve depressed is not available. Oxy will deplete real fast when cutting. Those sets are mostly used in the...

COVID slowed down the selling process. Just had neck spinal surgery a few months ago. Kept me down but getting back in the groove. So I am now back on the site. Sold all those welders except the Miller Dial-Arc. It may be an albatross. Need to start clearing out some O/A sets. Have...

I have a chance to buy a Lincoln Weldanpower 225 G7. Age and condition unknown at this time. Any one have a idea of top dollar to buy something like this. I will gamble on cost to get running. Also there is available a K 799 High Frequency unit for TIG welding. say I get it all working add...

Gary, I don't know yet. As soon as I get done with the Craftsman buzz box 230 amp I am currently prepping for Sale. They have a slide mechanism for adjusting the amps which needed some TLC, cleaning, and lube. This one had no leads when I got it; the tapered plugs are not made any more so I...
