Hello,I had an electrician come by today to install a 240V line, and I was under the impression that I needed a 50 amp breaker. He asked me if I wanted a 60 amp.So I am thinking bigger is better right? Or am I just wasting money on thicker wire I dont need? Currently I have a ****ty little inverter welder, but eventually I want to get a Miller, something like this perhaps, its quite pricey so I dunno, maybe I willGet a cheaper one, but I dont want to be hosed down the line cuz I went to small, and I cant find any power requirements on the site. What you guys think? https://www.millerwelds.com/equipmen...-welder-m30190ThanksEd
Reply:That unit you linked draws 32 amps @240v. A 50amp circuit would cover 90 percent of the electronic lunch box welders. If you have money burning a hole in your pocket go for the 60 amp circuit. My htp 221 runs off a 50amp circuit with no issues.
Reply:A 50amp circuit will handle every welding machine that comes from the factory with a 6-50 p (Plug) already on the power cord.Dunno what the price difference would be for the electrician to install a 60amp circuit. It really wont make much difference though so if it's a big jump in price just go with a 50amp circuit.If you think you will add more machines it might be worth it to ask about installing a sub-panel. It will be more $$ upfront but will save $$ as he will only have to pull wire once.You can another receptacle as needed in the future.Ed Conleyhttp://www.screamingbroccoli.com/MM252MM211 (Sold)Passport Plus & Spool gunLincoln SP135 Plus- (Gone to a good home)Klutch 120v Plasma cutterSO 2020 benderBeer in the fridge
Reply:Bigger's always better!For the fraction of what you're paying it costs to upgrade from an 50 to a 60A I would do it in a second (everything the job entails is pretty much the same, you're just going to pay the difference per ft in the wire)You Never Know what your future needs are going to be.

Reply:50A service will handle almost any modern welder that you're likely to consider. My Millermatic 350P is the most powerful roll-around MIG Miller offers and the manual calls for 61A input (230V single-phase) at rated output. I've been running it on a 40A circuit for quite some time...never once tripped the breaker.I'd ask what the price difference is between 50A and 60A and use that as a guide. Many (most?) electricians seem to either be unfamiliar with the wiring requirements for welder circuits, or ignore them and size conductors like they would for a normal circuit, so you could wind up paying extra for much heavier wire than is really necessary according to code.Check out my bench vise website: http://mivise.comMiller Syncrowave 250DXMillermatic 350P with XR AlumaProMiller Regency 200 with 22A feeder and Spoolmatic 3Hobart Champion EliteEverlast PowerTig 210EXT
Reply:A 6-50-R is designed for a 50 not a 60, machines that come with 50 end designed to be on a current limited circuit at 50.
Reply:The only machines that come fac end with 50 that require heavier than a 10 cable are some of the 252 class feeders with hi duty cycles. Even then not much a concern for home use, only a concern in production.

Reply:I would ask for a 50 amp breaker, nema 6-50 recepticle, and 6 awg (55/60 amps per nec) wire. Best to keep it all legal - and this setup is very safe.6awg is the largest off the shelf wire, and hence is cheaper than anything thicker.Done and done, ever need the extra 10 amps? change breaker and recepticle.

Reply:You can run 2 small machines on a 50. I wired one a while back The panel was out of more space and my bud bought a 211 and 375 plasma. We took the recept off the existing wire, a 6 or 8 and spliced on 2 number 10 to additional recepts.
Reply:New machines only require 14 wire,,, but this is single circuit in pipe and when this is done the breaker is limited to 30A. A legal 50A welder circuit is 12 in pipe or 10 cable.
Reply:The 350 is slightly differrnt, dont think it comes factory cord and plug?
Reply:Originally Posted by 52 FordOne recepticle or multiple? I have 2 NEMA 6-50 recepticles on a 60A circuit. I figure, if I have someone helping me, I can run two (small-ish) welders at the same time on that one circuit. Sent from my SAMSUNG-SM-G891A using Tapatalk
Reply:Originally Posted by SberryYou can do this but from a 50 not a 60. Cord and plug machines are designed for a circuit current limited with 50.
Reply:I don't see the point of installing a dedicated "low duty" over-rated welding circuit over a true 50+ amp circuit, unless there is some strange law or condition the price between the two is VERY negligible.If you can afford an electriction to install a circuit you can afford a TRUE 50 amp circuit. Aside from cost, there is zero advantage to a "dedicated welding" circuit, that by design, is dangerous to use at capacity with anything other than low duty cycle items.Last edited by SlowBlues; 3 Days Ago at 12:55 AM.

Reply:Fair points, my reasoning: It all depends on your local laws. I am sure there are places in America where a dedicated welding circuit is not legal. I am also sure 6 awg copper 60 degree min. wire is legal EVERYWHERE in the usa for 50 amps. Local codes always supersede the NEC.the NEC is nice but it is not the be all end all to building laws.6 awg is the largest prepackaged common off the shelf wire in "consumer" lengths.Yes you can buy larger wire off a spool at many places, or the entire 500/1000ft spool.Dedicated welder circuits are safe when used as intended, which is up to the end user. I don't put much faith in end users. I'm sure most electricians wouldn't advocate running a 20 amp breaker, and outlet, through a 15 amp rated wire labeled as "de rated" or "compressor duty cycle only". I see the welding circuit in the same vein, I wouldn't in my house or shop, but it is legal in many places and safe when used as intended.Last edited by SlowBlues; 2 Days Ago at 02:10 PM.

Reply:Originally Posted by 52 FordNot to start an argument...The breaker is there to protect the wire, not the load. I have plenty of 120V stuff that isn't capable of handling 15A, but has a 5-15 plug. A light bulb or a Dremel for example.I have been running my welders on a 60A breaker for years. I also have 20A breakers and 12 gauge wiring going to my 15A wall outlets. Of course, only do what you're comfortable with. Sent from my SAMSUNG-SM-G891A using Tapatalk
Reply:Tou have been doing it for years but that doesnt make it code compliant. Nothing has happened but this deceats the intent. Its rather marginal. It eill run from 100 or 200 too but in the event of a fault there will be anothrr problem.
Reply:I would use a 50 or 60 amp 240 volt plug.Dave Originally Posted by tryonixHello,I had an electrician come by today to install a 240V line, and I was under the impression that I needed a 50 amp breaker.

Reply:Your dremmel is designed to open or short to tbe extent it trips a breaker. The "handle" part of it is that. Some have additional internal protection like the wire welder, some none like a buzzer. Some partial like controls or thermal on blower burners etc.
Reply:Miller has some new genius engeineers. With electronics they need them but,,, some are living proof you can become an ee without opening the code book. If it was so simple as a breaket and a wire wouldnt take 1000s of hours education to do simple circuit design.

Some have additional internal protection like the wire welder, some none like a buzzer. Some partial like controls or thermal on blower burners etc.An example. Fixtures in house hard wiref to 20a. Thrrmal proctetion not from breaker but due to the fact the lamp base will only accept 200 watt luminaire. Lamp wont overheat the wire. Wire must be able to short a 20.Last edited by Sberry; 1 Day Ago at 11:02 AM.
Reply:Originally Posted by KelvinIs there anything that is, strictly speaking, actually "LEGAL" in Southern California?
Reply:Look at allowance for welders. Modern ones allow 14 on 30A. ACbuzzer. 12 on 50A , single circuit in pipe or 10 cable.Buzzer comes 12 cord 50A end. There is some lost zip with longer 12 circuits. Mostly goes away with 10 and a 6 is 2x as good as the machine requires and doesnt add to safety.Last edited by Sberry; 1 Day Ago at 11:42 AM.
Reply:I seem to have struck a nerve. Wasn't my intention.An example that I omitted from the last post.... NEMA 5-20R. You can plug a 5-15P into them. The breaker protects the wiring - not neccessarily the load. Again, my wall outlets have 12/2 wire and 20A GFCIs even though I installed all 15A outlets. Might not be NEC compliant to a T - I don't know... but it works perfectly fine and is not dangerous. Sent from my SAMSUNG-SM-G891A using Tapatalk
Reply:I guess I have a dedicated circuit for welders, and heaters 6ga drop either runs the welder, or the two heaters in the shop (22amps each). I don't know of any other way of doing it, outside of buried bigazz cable running a panel in the "shop". I'm strictly from the power pole, directly under the meter. I keep the extension cord industry in business
Reply:15 on a 20 is compliant.Again, my wall outlets have 12/2 wire and 20A GFCIs even though I installed all 15A outlets |
