I BOUGHT AN OLDER MILLER 330 AMP TIG WELDER AT A DECENT PRICE, BUT IT WEIGHTS 900 LBS AND REQUIRES A 100 AMP FEED,
I saw the price of 100 amp disconnect plugs at the local electrical supply and said thats nuts! a plug and socket costs $500???
I ran into the same problem with my 100 amp feed on my 330 amp tig, the correct plug/socket listed at almost $500 at the local electrical supply
(THATS TOTALLY NUTS)
so I thought about it a bit and bought three of these TWIST CONNECTORS FOR WELDING CABLES

theres a MALE and FEMALE END to each TWIST CONNECTOR
BTW they cost me about $20 each at the local welding supply
painted two red and one green
ran three feed wires in conduit to a large plastic storage box with a cam loc front pannel
ran a 50 foot long tripple feed cable attached to the welder inside 2" flex tube
the green is ground the two reds are power, think about it a bit, it works great, I simply leave the 100 amp electrical braker off , unless they are connected to the welder and you can,t screw it up because its both color coded and the ends won,t connect wrong physically
hooked up the green one from the wall connection with the extended male side of the connector extended, ran the two red feed with the enclosed female side from the power

walls got two red female and one green male connector, welders got a 50 ft extension cable with two red male and one green female connector
the 100 amp breaker keeps power from the connectors unless they are connected and the connections are made in a 18" plastic water resistant electrical box with a lockable lid mounted 4 ft above the floor
just use the correct ga. I used 00 GA (2 OUGHT)

THE 50 FT TAIL ON THE WELDER ALOWS ME TO MOVE THE TIG ANYPLACE IN THE SHOP AS THE CONNECTORS ON A WALL MOUNT NEAR DEAD CENTER BETWEEN THE GARAGE DOORS
