This manual may be enough 117-050 Owner's Manual

Don't really need the original gas conversion kit if it has the solenoid valve. Just get a gas regulator and bottle at the welding store. You need a 75%Argon 25%CO2 bottle for quality steel MIG welds. The Century might be Lincoln. Ask for help at the local welding store.

220v
Electric Stoves are usually 50amp.
Electric Dryers & AC are usually 30amp.
Air Compressors, Table Saws, Small Mills usually 20amp.

Most Older Homes pre-1965 have 75/100amp Service, newer Homes 150/200amp Service.

I have 200amp to the house and run a 100amp off that to my garage. My 220v Stick Welder needs a 50amp Circuit. My Mill uses a 30amp, and my Lathe is 30amp as is my Air Compressor. None of them have overloaded my circuit breaker in 38 years.

Many Military Generators have 220v and can be bought cheap at Government Auctions.

A DuroMax Gas Powered Portable 12,000 Watt Generator has both a 50amp/30amp Outlet! $1,199.00 on Amazon. The 10,000 (On Sale $699.96 )and the 11,500 ($1,049.00 )also has both 50amp/30amp 220v Outlets.

For upgrading your Home should be Free up to the House, you might need a New Box inside. I would upgrade to 200amp for the House, then run 100amp off that to your Garage/Shop. Electric isn't Rocket Science 110v Black, White, Ground, 220v Black, Red, White, Ground. Check your local Codes.

14 gauge 15amp
12 gauge 20amp <-- My House & Garage 110v is all 12ga.
10 gauge 30amp <-- Shop 220v 30amp is all 10ga.
8 gauge 40amp
6 gauge 55amp <--- Shop 220v 50amp is 6 Gauge.
4 gauge 70amp
3 gauge 85amp
2 gauge 95amp
========================
1/0 gauge 150amp Service
2/0 gauge 175amp Service
3/0 gauge 200amp Service
4/0 gauge 225amp Service <---- I have 200amp Service but I used 4/0.

I've known Dustin since 2012 - He's a good guy, and I'm sure do anything he can to assist.

Alana, there are several other people in the Tehachapi area that may already be set up for welding, perhaps you can find one of those people and use their setup. I'm hoping you know Dustin Mosher and some of the other folks at Tehachapi, there's one guy up there (forgot his name) with a bunch of antique airplanes in his hangar, I would be very surprised if he isn't already set up for welding.

What kinda airplanes you got stashed up there already???

BTW, I believe we are going to have the big Experimental Soaring Association event on Labor Day over at the gliderport, several of us from HBA always participate in that event and it's a great time. You might think about being there with us. It's always great networking (in the "strange airplanes" world) and they always have interesting speakers. Just being in the same room with Al Bowers for five minutes is clinically proven to raise someone's IQ by36% :)

Miller IIRC, recommends 10 KW genset for its smaller 240V inverter welders. Yes, they will never use that much power but that is the OEM's take on it. To put things in perspective: My trusty 38 year old AC/DC Stick/TIG machine will trip a 60 amp 240V breaker on full load. My Miller 211 inverter will trip a 15A 120V breaker if run full load past duty cycle limits, but will seldom trip a 20 Ampt 120V, and NEVER a 20A 240V circuit. These are pretty close to the same welding amperage at their limits. There is THAT much difference between old transformer and new rectifier. So, you SHOULD be alright.

I was always told welder use was far more a matter of amps than watts. But since generators are rated in watts, and since amps is one of the factors used to determine watts, you always hear a minimum wattage figure cited when using a generator. Since Tailwind Fan's generator has a plug with an amperage rating that's seemingly suitable for her welder, she should be fine.
