Can I make a dedicated welding outlet (light welding only) in the workshop?

I so can someone advise circuit and breaker size?

 

Thanks

 

Pretty much all of the DIY welders run off a regular outlet anyway, so running a dedicated circuit in 2.5mm² on a 20A breaker is the way to go. If your welder has a Schuko plug then do install the correct outlet, same wiring and breaker.

 

Nothing to stop you going with a 32A Commando outlet on 4mm² and a 32A breaker if you have a bigger unit.

 

Don't forget it will need a ground ????

 

 

Thanks Crossy, you're the man, knew the answer would be simple, but best to check

I routinely run my "inverter" welder over 20m of 1.5mm² extension wheel (on a 10a breaker) and nothing ever even gets warm.  I hardly ever go over 60a setting though.  Just sayin.

Sorry i am on the wrong topic,i taught i saw 'wedding outlet' and wanted to be the first to wish

NCC1701A all the best.

again,i am sorry.

JVS, not just you're eyes are knackered, but you're computer spell check isn't working either ????

I've 15m of 2.5mm twin left over from my solar install, I added a plug and socket for use welding around the place, no earth, works fine.

 

Why do I need an earth, there's no earth on my welder plug?

Double insulated? Or a Schuko plug?

 

Back in the day of stock car fabrication there was at least one guy in the village who didn't have a welding machine so he simply connected his welding rod holder and ground clamp to a cooker socket and welded his chassis at 220v. 

 

This did not endear him to his neighbours watching TV!

I have several dedicated 4mm² outdoor sockets in covered boxes to use for the 3 'bbq' fry cookers on 'family night' or for powering construction equipment. 

 

Don't know why I even bother as invariably I'll discover the power has gone out as a work crew has dismantled my CU to poke in wires on the 50A main breaker to power their sketchy extension cord running their transformer-based welder to do a project the family ordered -- they having already loaned my inverter welder to uncle so he could finish building his new house. This is Thailand. There's no need to plan anything as it's very unlikely that anything will go as planned. Sigh.

There was an outfit in the Philippines that was actually selling a device to do this, it did have some sort of current limiting device inside. Apparently the word "safe" does not appear in the local language.

Who said one was needed?

 

My in laws had an outlet for welding that was wired directly to the mains OUTSIDE the house, so no circuit breaker. I nearly discovered it by putting my hand on the bare wires as they were covered with old junk. They had kindly omitted to put the cover on the knife switch. Obviously I did put a cover over it. Came in useful when I borrowed a big welder to weld the fence, as it kept overloading the circuit breaker on the inside plugs. I used it very carefully.
