HMMMMMMMMM Until sparky gets here with his input and expertise, I have some heartburn you can take or leave as you wish. I retired from designing secondary power distribution years ago so am rusty and NOT up on the latest NEC like sparky likely is, but here goes FWIW
QUESTION:
Garage 150 ft from house, #10 /4 wire under ground. 220 receptacle for welder in that garage.with a 100 amp breaker box.that is protected with two 50 amp breakers.
ANSWER:
I trust at the panel where those No 10 wires originate that circuit is protected by a 30 amp two pole (interlocked) breaker right??????? If youre just using 30 amp wire to feed the garage whats those 50 amp breakers all about???
Many of the typical 240 volt 225 amp AC Buzz Box Welders take more then 30 amps (still depends on load remember) DID I READ YOU RIGHT YOURE ONLY SERVING THAT WITH 10 GAUGE WIRE AND 150 FEET AT THAT. I wonder what your voltage drop is ???
QUESTION;
The house has a 150 amp box with the garage on on a second breaker box to completely shut off power to garage if needed.
ANSWER: If the garage has 120/240 volt service ran to it from the main panel, I hope there are 4 wires (2 Hots, Neutral, Equipment Ground) ran to it and I also hope the Neutral and Equipment Ground Busses inside that sub panel are isolated and NOT bonded to each other like in a main panel??????
QUESTION:
When power is lost I simply unplug welder and plug in generator.
All secondary grounds are covered except one from Generator. The generator has a 4 wire plug and the receptacle for the welder is a 3 wire.
ANSWER;
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
You cant (NOT saying it wont work, its just code violation and can be hazardous to your health) use that 3 wire setup as a backfeed for 120/240 volt single phase 3 wire service YOU NEED 4 WIRES (2 hots, Neutral, Ground)..... That welder receptacle ONLY has 3 wires, 2 Hots and Equipmenmt Ground. YOURE MIXIN N MATCHING NEUTRAL AND EQUIPMENT GROUND Also the gennys Neutral to case/frame bond (if it ahs one) should be severed when used to feed your home
NOTE::::::::: Okay im glad to help here all I can and a couple days ago spent HOURS explaining and covering all this emergency genset power and backfeeds and reasons for 4 versus 3 wires and why YOU CAN NOT MIX GROUNDS AND NEUTRALS etc etc its alllllllllllll a few pages back BOTH here and/or over on Tooltalk and theres no sense in retyping it all over again lol so take the time to look on those two boards for the longggggggggggggggggg thread where I previously explained all this and your questions are already answered.
As I posted there, dont you non electrical types feel bad cuz its IMPOSSIBLE to explain in a few paragraphs here what it takes books n books n years of experience to comprehend so do it yourslef if qualified or hire a good electrician otherwise cuz the life you save may be your own
Yall take care n n God Bless n keep warm n safe and MERRY CHRISTMAS

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
