Bridge Rectifier, MDQ-300A 300A 1600V Single Phase AC to DC Full Wave Diode Module, 4 Terminals with Isolated Mounting Base for DC Motor & PWM Converters

Added this to my Lincoln 225a AC welder in order to get DC welding capability. It works great.Mounted to the front of the housing, and wired it with connectors to be able to use AC or DC by connecting it inline of the weld cable.

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.

The actual product is different from the one on the web.... But.... None the less all the specs are exactly the same... So that's all that matters... However the product is a solid product.... Nothing cheap....!I'm using to convert a AC welder to DC... and this heavy duty rectifier will do the job... Would recommend to anyone looking to do the same.... Solid product... You won't be disappointed...!
