Review on 💪 Efficient Power & Hand Tools: RIVERWELD DKJ10 25 DKZ10 25 Dinse Style Connector for Industrial Use by David Cook

I need to make extension cords for welding wires for a 225 amp welder. They were the same size as the panel plug on my Harbor Freight welder (100-200 amp plug - Harbor Freight doesn't build anything). Worked great with 4AWG wire and was very easy to assemble. The wellies come with keys and the keys are marked on the front. First I assembled the male ends, then the female ends to not mix up the rubber boots as they are different. Sleeves allowed me to use wire with open and crimped ends with very little effort - without sleeves I would have to snip the crimped end and strip the insulation to insert four gauge wire into a jack. The assembly took only a few minutes. Very satisfied.
