Works good on my Lincoln 225 Arc Welder
Used this to convert a Lincoln 225 welder (aka tombstone welder). Works good. Welds are smoother.

Works good, makes my ac welder into a smooth running dc welder
A very good bridge at a bargain price

Works great to convert older AC buzzbox welders to DC
I bought this BR to convert my older Century AC “BuzzBox” welder to DC, as other buyers have done & as shown on several YouTube videos. I chose to retain the AC welding connections and tied the bridge rectifier into the existing system using new 2-gauge welding cable and adhesive-type heat shrink. It works! And it works great! Really makes welding with 7018 rod a breeze (cleaner welds, easier to keep burning rods, less splatter, less current required). Keep in mind that for clean 7018 welding, you will need to use a POSITIVE ground; this didn’t work so well for me with 6011 so I switched back to Negative ground for 6011 and it worked great that way. I installed Riverweld Tig-welding plugs/connectors so I can easily switch between Positive/Negative ground depending upon which type of rod I am using. Very happy with this Bridge Rectifier!

Does the job.
I used this to turn a cracker jack lincoln AC stick welder into a DC which makes a HUGE difference. Now I just need to add an internal fan to up the duty rating.

Ac buzzbox
Worked great on my ac buzzbox! It's a real stick welder now. I was at 135a on ac welding 1/4" steel with 1/8 6011 had to drop it all the way down to 75. I'm am very impressed with how well it works so far but I have only burnt 5 rods the day I wired it up. Can't speak on longevity yet. Don't count on a seccond review because I won't remember to come back and write one.

Gotta take the good with he bad
Worked to convert my tombstone for about 2 uses. I know it was wired right and used new leads 4ga. To wire it and add the quick connects. Just glad it burnt up and not the welder. Bought a different rectifier and not it works great. It's electronics sometimes u get a bad one. Just wish there was a way to get a refund but cant prove it wasn't my fault. Oh well
