ok, new welder arrived today...
Last weekend I did some shopping for the power requirements.
I think I have all I need to power up the welder after installing everything this weekend. I love home wiring so should be fun..
I had a new subpanel from a project that never came to be. I decided to include that in this project so I can have a breaker for lights and a grinder.
New 50 amp breaker for the main and another for the subpanel. I have small breakers in the original subpanel so I will not add that cost here.
New 40' of #6 SCR (main to sub, sub to outlet. it has an extra conductor for the neutral of the 120 circuits.)
New 50' #10 extension cord from HD.
New 50amp plug and socket to adapt the extension cord.
New 10 clamps to mount the #6 SCR to the basement ceiling.
New 4 3/4" bulkhead clamps for the #6 SCR to both panels and the wall socket.
As this subpanel will be in a sometimes moist area (large below grade basement entryway) I will mount it and the 50amp socket in a recycled weathertight fiberglass panel that is large enough to hold the #10 extension cord.
The #6 SCR was very reasonable at about $1 per foot. I could have bought #6 SEU at $.75/foot but wanted that neutral for 120 circuits. An electrician at work talked me out of running #10 from the main to the subpanel, despite the duty cycle argument. That #6 SCR is aluminum and was cheaper than the #10 extension cord from HD. The #10 extension cord will be used from the exterior subpanel to the work area which this summer will be primarily outside in the gravel driveway.
Welder $419 Hobart AC/DC stickmate
Wiring $170 2x50A CB,40' #6SCR,50' #10extcord,plugs/sockets,etc
I think I have everything else I need to safely strike an arc by sunday night....
Oh and I will likely not do a welding cart but rather will modify an existing handtruck for this summer's welding..... I damaged one of my homemade tractor bucket forks so replacing it has now become the target first project...

time will tell....
