whats the biggest input amperage welder u can get in single phase??the top and bottom of it is you cant get a single phase to run at 350 amps + Put three phase in, get a 3 phase genny or diesel driven plant
whats the biggest input amperage welder u can get in single phase??
If this is the case then why do they make 700 amp TIG sets?A bit of a misconception by a lot of people is if you are welding thick plate you need loads of amps/power. There's a limit to how much juice you can throw in there until a weld bead becomes unmanageable and slumps/runs away with itself and looks a mess.
It's more to do with the duty cycle of the machine, epecially if you are laying a number of runs. If its low and keeps cutting out the duty cycle of the kettle comes into play!
Pinch of salt is more or less a requirement on here these dayswhats the biggest input amperage welder u can get in single phase??
most domestic supplies have a 60 amp mains incommer cutout fuse . some have an 80 amp or even a100amp supply . so if your supply was 80 amp u could quite easily run a 60 amp welder no problem
thanks thats what i was lead to believe but wanted some advice from welders rather than sales men think i may have to hold out a bit longer until i can get 3 phase then
you better disregard all that theory,a dealer said so.I suppose it depends on the quality of the supply. If it's come a few hundred yards from a transformer on a couple of poles there might be quite a voltage drop if you were drawing 60A.
350Ax30V=10500W (mig current x arc voltage =Watts. )
10500W/230V = ~ 45A.
Factor in the welder being say 80% efficient.
45x 5/4 =57A
The welders WMJ has used will be more efficient and will have power factor correction. If he says he's done it and it works, I believe him.
There was a pottery kiln at school which was single phase and had a 60A fuse.
it must have been an old p....ss poor transformer and feed. the boards cutout fuses generaly match the size of the supply cable so the cable cant be overloadedIve used single phase Migatronic and Oerlikon machines. From memory, they were labeled around the 320a mark.
Used for some fairly chunky steelwork. on single phase 32a supply.
The supply wasnt really upto it, wiring on the wall used to get warm, and the incoming cables used to get warmer if there was 2 of us both welding.
Lost all power one day, the electric board came out to discover we had blown the transformer on the pole outside
