looking to get an adapter to go from twist lock 220v(3prong) to 3 prong welder 220v. I know I could make it but would rather buy one due to my lack of electrical skills.

Generally the plug on the welders are Nema 6-50P and the wall will take a Nema 6-50R (P= plug and R= receptacle)

Is your 3 prong plug and wiring setup for the 50 amp rating (sometimes lower like 35 amps, depending on what your machine calls for)

What machine are you planning on running?

I was in need of an adapter as well so I took the opportunity to add mobility by making my adapter 25' long!

The easiest way would be to cut off the 3-prong twist lock and replace it with a NEMA 6-50P. Electrical skills aren't necessary. Strip 1/2" of insulation off each wire, insert into the terminals and tighten screws.......done! The better way would be to do as rmmiller said. Put 25' of extension between the plug and receptacle. I did that too. Now I can move the welder anywhere in my shop. The standard 10' cord didn't work. I found a 25' RV power cord at a garage sale - $10, spliced on a 6-50 plug and receptacle and now I've got 35' of power cord.

BTW, you're gonna need at least a 50a breaker for that Lincoln!

Grrr !!! One of my personal "pet peeves" ! Why do the put a 50A plug on a welder that is not going to draw more than 15-20A ? Personally I would cut the plug off and install a plug that will work with your existing receptacle(s).

It is highly UNLIKELY that you will find one made up. You will have to "roll your own" !

L6-30P (3 wire, 30A, locking)

I was in need of an adapter as well so I took the opportunity to add mobility by making my adapter 25' long!

Great suggestion ! And I found 2/3 of this already made up !
