what does it mean 25amp i have a 13 amp plug will these work how do i get 25amp supply

 

[the snooper]

it means you need a 25 amp plug, socket and cable capable of supplying 25 amps from the mains distribution box

 

[Wozzaaah]

In what context are you asking? Do you mean output or input?
If the welder requires 25 amps to run it then it requires a 25A supply, simple as that, i.e you won't run it from a 13A plug as it'll blow the fuse.
If the welder is 25-whatever amps then that refers to the output current, the input supply needed will be whatever the machine spec says.
Hope that clarifies.

yea it needs 25 to work do you take the lead from the fuse box are do you get a 13 amp plug plug it in then have a special plug

 

[jonjoe]

also the welder is swp mig 220 i was wondering could you put a full size welding bottle on it.

the welder on weldequip

If you're asking questions like that then you get a qualified sparky in to do it and certify it so it's done properly and safely.

No probs putting a gas cylinder on that, it will have a shelf on the back.

25 amps is fairly close to a 'normal socket cable' limit,so it would be better to have it done professionally

Taken from the info on the weldequip page:-

"Input Fuse: 25A @ Maximum 220 Amps (13/16A on lower ranges)"

So, if you're not using it flat out, but on the lower settings, you'll get away with a 13A plug.

Keep turning it up until you blow the fuse, and you'll then know how far you can "push it" on a 13A plug. You'll do no harm by doing this. Any higher up the range would need a higher rated supply/plug.

All the Best,

i heard about a welder which kept cutting out the man changed the breaker in fuse board to a industrial one and it worked then could i not just do that

 

[weldequip]

also the welder is swp mig 220 i was wondering could you put a full size welding bottle on it.

Yes you can. That model has 12 voltage settings. It needs a 25amp supply just on the top 2 settings; a standard 13amp supply will be fine up to around 150-160amps (4-5mm mild steel). What type of work do you want the machine for?

And for gawd sake don't fit one of these "fuses" when it blows cos your house wiring will then fry (In this case the welder fried hencs needing transformer rewind) Not fried by me I may add, just mended by me Not sure of the amp rating of a M6 BOLT!!

No, you've still only got normal 3 pin 13A sockets so you can only fit a 13A plug in one!
The 13A fuse is the weakest link in the supply, it should blow before the breaker trips so fitting a C or D type breaker won't help you at all.

 

[jonjoe]

well i still young yet 15 i have a inverted stick welder but would like a mig when i save enough for later in life but now im welding box iron noting to heavy and if i keep the amps down i could do a couple of passes to build up the weld anyway

[jonjoe]

so i need a bigger fuse to put in the plug, like the bolt as a fuse i wouldnt do something like that i hope

You need a 32amp plug (closest size up from 25amp) on the supply cable of your welder.

From the electrical supply be it a consumer unit or distribution board you need a 32amp socket protected by a C or D type 32amp MCB depending on the welder.

The cable size from the distribution board needs to be a minimum 4mm squared diameter depending on how long the run is and depending if the cable is run in free air, clipped direct or run in thermal insulation. The most likely size of cable you will need will be 6mm squared to be able to safely carry the current required at full load but the IEE wiring regs will need to be checked to be sure.

Such a supply can be run from your house so long as it is a single phase welding set and not 3 phase and providing it is wired to current wiring regs.

If any of the above sounds like a foreign language you should definitely consult a qualified spark, IE. me.

Not sure of the amp rating of a M6 BOLT!!

Around 3000 amps and even that's being conservative!

 

[jonjoe]

thanks i think im might get someone to do it for me lol will it be costly

2.5 cable can run 25 amps.27 even at a push

You're not paying attention Jonjoe!
You CAN'T put a bigger fuse in a 13A plug as it's designed to take a maximum fuse of 13 amps!!
