    Yes, doesn't surprise me a 300 tranny trips a 60, I was referring to 50 in machines. I have a Rigid chop saw routinely trips a 20, got a special circuit for it. Probably didn't help a lot my helper upsized the wire to a 10, no sag when it starts, really hammers on. Tossing in 25 ft of 16 cord helped a little back then but now its on 30 and it works, I have metered it, the thing can really spike. Only thing I owned that really ever tripped a breaker under common operation. Maybe a little compressor when it got plugged close to a panel.

    I am a simple installer of the type of equipment I work on, easily confused by controls and 3 ways. I auint all that fascinated with electric as I think I should be which is partially the result of having help I can lean on. My interest is forensics and inspections, I wanna make sure it passes and complies, not an intertest when I started wiring and my install copy skills are good enough that a lo of people didn't know I didn't know.
    What I thought I knew and understood is now what interests m due to the constant repeating nature of forums and where I really took an interest in code compliance. Some always told me was a poor way to learn and no one took the time to really splain some basic concepts I didn't fundamentally understand in both and including paint booth design, some plumbing concepts and basic AC wiring. I opened the book along with the forum and spent about a year on diy beating a guy to the answers. It finally clicked at a couple points and then it was practice till its a reflex. Not learnin nuthin new but practice till short circuit interruption was a reflex in circuit design and code compliance and ask a couple guys who finally splain it till I understand or at least to the level I can comply.

    Don't mean I know any electric some of these guys do, I just fit it up real neat like with a little do it twice till it looks right even on occasion but the **** looks like it belongs there. Wireman or installer I think more than real sparky at heart. My only interest is meeting some demand I need.

    If you study code, 90% is protecting it from harm.

    I was this afternoon at a manufacturing facility I work at often. The wall of a storage building had been moved a foot by an inexperienced operator in a loader. Numerous conduits had been ripped out of place. Exposed individual conductors were visible in several places. They were exposed to weather on the outside of the building.

    I was there for another reason. Nobody troubled themselves to call about this damage. If I hadn't been there to notice today it would have been ignored until it failed.

    I carry the safety card. I can insist on a repair management would prefer to defer until a month from now, in the middle of the night it results in fire, or more probably, a machine won't work. Then they would call at 1:00 AM: "The feed screw won't work!"
    I caught this one before failure. More often they wait for middle of the night failure.

    I often point out failures only happen between 9:00PM and 5:00 AM. They chuckle.

    There are no emergencies, only ignored warnings.

    An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.

    There is a guy named David Todd Geaslin from Texas has a good take on this and has courses expressively for management types who need to get a grip on the real cost of defered maintenance. Says most of them got the math wrong.

    This facility is unbelievable! I accuse the employees of being able to break a cannon ball. They have fast turnover of employees. Two of three shifts, they are unsupervised. I believe there is some drug use at night. There is at least some damned careless behavior.

    I have had some cases where they claim the required disconnect switch for a machine "tripped" I explain there is no mechanism to trip. It is only a manual operated switch intended to turn off while working on the machine.

    Re: Electrical requirements for new welder

    I was in one, they were going to get some maintenance people, they would train them in a week. This is college boys know most everything that said this. I asked, where was the electrician, the guy points to a chart on the wall, says there he is. They didn't have one, guy running this doent know that. Yes, I been in the places, I was really a drop out. got tired of being talked to like I was stupid by mba types running it in to the ground.

    You might need to contact electricians Hawthorne to properly protect your shop for shorts that may happen from welding. It consumes big amount of power.

    Myself personally if installing a 6-50 50 amp welding outlet I would use #6 and if the machine didn't need a 50 amp use a 30 instead but the rest of the job is only a breaker change away from delivering 50 amps if needed in the future.

    That is comical. And your electricians. OK !!! LMAO !!!

    A little 215 welder doesn't consume big amounts of power and welding doesn't cause shorts in the electrical system unless you seriously have screwed it up.

    It is simple a stick welder needs 50 amps 240 volt.
    Most MIG for most work up to 1/4" only uses 20 amps 240 volt.
    Still if putting line I would use 50 amps 240 volts plugs for both.
    Remember you can only use one at time. So 50 amps is all you need for all.

    My question is what size circuit breaker do i need? I see in the documentation it says a NEMA Type 6−50P. Does that mean it needs to be a 50amp breaker? I thought I read somewhere 30amp breaker.
    What wire gauge size would I need? Not sure if I will run the line myself or have an electrician do it, but I do need to know what to ask for.


    Also, any recommendation over the Miller 215 or the Esab Rebel 215? I want to use it for fixing things around the house. Probably some stick welding and repairing a small aluminum boat using a spool gun.
