Lincoln 225A ac vs ac/dc

Hey all,

I have access to a 225A AC lincoln arc welder. I ordered a truss / bracket setup from artec and plan to get refamiliarized with it then weld up these brackets.

I was going to buy a 225 AC / DC until I found out my brother has my uncle's old lincoln 225A, so the question is, will it work as well as the ac/dc variant, or would I be better off spending the cash & getting the ac/dc welder?

I only plan to really weld this axle, maybe a couple of bumpers or quick fixes, and maybe, MAYBE, Down the road ill weld up my own cage.

Also, I have used a stick welder before, welding large plates into dump truck beds for my frieds dad. That was 20 years ago, but I remember the process, and I have read in this forum about the correct sticks to use among other things.

Any ideas, help, suggestion would be appreciated!

IMHO, you'll be just fine with the ac only machine, sure a dc machine will run a little smoother, but for starting out a cheap to purchase/borrow ac machine would be my choice.

Good luck, Don

Thanks ironworker! I did make sure to grab the AC sticks, and am hoping to get a bit of 'practice' in this next week. I have to get this thing done for a jeep jamboree in AR Oct 22. So I am about to see how much I remember, and if it might be in my best interest to just try again with a local shop (really wanting to avoid that, but...)

Thanks

Wow im shocked you found an old Ac welder lol. You most definately can weld that with AC but Ac/dc would leave you alot better looking weld. We grew up calling that Old Farmers rod. Ac just burns loud and funny. Unless you have a big mig with at least .045 wire i would use a stick welder all day long for penetration reasons. Practice you horizonal and vertical welds. Vert welds will be most tricky for you with a stick especcially Ac rod. Dont forget the cleaner the surface the better. Rod flux only protects so much unlike gas.
