...I've installed a dedicated 50A circuit breaker in the garage sub-panel and a completely new/separate 6-50R wall socket...
Uh, Oh. Hope you haven't caught the disease. I started out with a 30A outlet in the garage just in case I got a decent compressor or whatever. Then got a MIG and decided to go with a separate 50A as well. Then there was this stick welder... and then a Syncrowave 250 that just begged to have it's own 70A breaker minimum... SIGH. Now I wonder if I can up the main breaker in the sub-panel from 100A to 120A. Then maybe I could do some arc-air gouging and burn the place down once and for all.
Is there some over-the-counter medication for this?
Not thats ita a good idea but it can be both legal and safe.
If you are hinting at the oversized breaker and downsized wire due to the duty cycle of the welder, A 50 amp breaker and 50 amp receptacle on #12 wire both exceed the allowances in the NEC for the duty cycle on a welder.
Congrats on your 211. Get a couple of fire extinguishers, a 5 gallon bucket with water, and have a garden hose connected if needed. You can also get those harbor freight welding blankets too. Starting a fire when it is not intended is not good. Wife may get upset. Those sparks have a way of find places to hide. Good luck.
Its at 50 depending on the method and type. A Stickmate or Linc buzzer can be 12, single circuit in pipe. No one thinks ita a great idea. It has to do with the machine, a 211 can use cable with 12, ideal for 2 machines in this class with only 1 breaker.
This is why the 35 max brkr when used with 14 for the 211 type machines, use the minimum wire you have to reduce the ocpd, above that it can be up to 50A.
