Miller Multimatic 220, question about 120v operation

admin

Maybe I'm missing something but can you actually even run this thing effectively on 120v? Obviously it has a 1-15P for it but it draws up to 24 amps even running on 120v. So you would want to run it on a 30 amp breaker but as far as I know, those 1-15r receptacles are only good up to 20 amps. Is the idea that you would put it on a 20 amp circuit and just try not to trip it?Seems like if I'm going to run it dependably I'm gonna need to install a 30 amp breaker anyway so it seems like I might as well just make it 240 while I'm at it. This brings me to my next question: If I'm not going to be doing much stick welding I'd probably be fine on a 30 amp breaker, but that nema 6-50 is meant for 50 amps. Can I put that 50 amp receptacle on a 30 amp circuit or do I really need to go for the heavier gauge wire and bigger breaker and everything?Last edited by jackhmullen; 01-18-2021 at 10:04 PM.

Reply:"Can I put that 50 amp receptacle on a 30 amp circuit or do I really need to go for the heavier gauge wire and bigger breaker and everything?"Yes.If you have to run a new line, might as well put in a 40amp breaker #8 wire. But if you already have a 30amp circuit and just need to change the plug to 6-50,  that will work for what you mentioned.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
