Welder wiring
Sorry for another welder wiring question but want to make sure I have correct wire. Welder says 240v 60hz 20amp with 110a at 20% cycle rate. I have a 50 amp breaker (welder plug is 6-50P) and have some awg 8/2 (with ground). Can I use this 8/2 for welder only outlet safely. From panel to outlet is less than 10 feet. Going to replace wire on welder with same plug but add a 15' cord. So will this be safe and correct? Does wire from panel (in wall) have to be ran in anything like plastic tube? Thanks for help.

I am no electrician but i do weld. Appears you have a small mig machine similar to my 175 miller. Those are 20amp 220 machines, not like the old 50amp service for the buzz boxes of years ago. As recommended, suitable receptacle and sub panel will get you going.

Thanks for all the info. Not sure why they put the 50 amp plug on all the welders. I figure it will be overkill but because manual called for using 50 amp breaker I will run the 50amp with 6/2 from breaker to outlet. If you mind just one more question can I use 6/3 and leave neutral capped at box and outlet. This would give me option later to run anything I may need that I don't know about now. Thanks again for everyone's help.
