Posted By Topic: 15 amp plug

Neg

Hi
I purchased a 170 amp DC Inverter welder recently ( this one to be exact http://www.esseti.co.nz/xaarc170-inverter-welder-p-90.html ) and had a question regarding the 15 amp plug.

I had been told I can file the earth pin?...so it can fit into the 10A plug, to be honest I'm not to keen on this and would probably void the warranty on the Welder. Just want to know what would be involved and how big of a job to change from the standard 10A socket to the 15A.

And when it comes to extension leads is there any particular lead recommended for running a welder, how long of a lead can I run?

First question would have to be 'what effin idiot' told you that?.

No big deal to change a socket to a 15a unit but you have to be sure the cable and circuit is big enough to take it, and the breaker/fuse is correctly rated for the job.

As for the 'lead' question. Avoid one if you can, move the job closer to the socket, but if you must use one, the use one as short as possible and make sure it's correctly rated and has 15a ends. You may need to have one made up for the job. (i'm not aware of any 15a leads on the market)

The place where I purchased the welder from advised filing the pin.....He even sold me a file. Would prefer not to name.

I would think the cable and curcuit is big enough as I will be most likely using the welder from a milking shed.

I would assume an electrician would be able to make a 15a lead. If so roughly what cost should I expect for the lead and a 10-15 converter? Is the converter just a plug/socket that plugs directly on the 10A socket

Yes. its a short lead that plugs into the 10A socket , and off that is an enclosure fitted with a 10A Circuit Breaker , then there is a 15A plug so your welder can plug in....

What it does is limmits the power through the lead and plug to the rating of the socket outlet.


The other option would be to change that socket on the wall to a 15A job , but u will need an electrician so the first option is prob the best one.

Cable required could be calculated via Load-minus voltdrop + Impedance/distance.Pay to get an Electrician,be worried he he asks for a file..4mm good for 35metres.beaware im very rusty on the new rule changes.

Would limiting the power to 10A affect the welder?
If going down the route to calling out an electrician, what exactly would be involved in changing to a 15A socket?

Not wanting to be an old moaning git...but... Why not just play it safe and get a qualified electrician in to do the Job for you and do it properly?

As for the person who sold you the welder and file with the recomendation of filing down the earth pin...why not mention the name of their shop? If that's the kind of professional advice their giving out then they deserve to be mentioned.

That's my rant over ...

+1 Mick, couldn't agree more. Came across a 20Amp Flat pin plug (fitted to a 250Amp MIG welder)which had all three pins filed down to fit a standard 10Amp outlet 8-( OMG, guy that owned it, said he's been give the same advice.

As useful as they are, it would probably be better if flat pin 15 & 20 amp outlets/plugs were outlawed, and only the round pin equivalents were permitted.

unfortunately it must quite common for sales people to recommend filing the pin , i have heard of this bad advice a few times now

hpm make a ext lead with 15 amp plug and cord connector , its only 1.5 mm though and max is 20 metres

Heard a story the other day about an osh inspector that discovered a 15 amp plug on a welding set that had been filed down for use with a 10 amp socket in a temp power box on a construction site. He recommended that the 15 amp plug be replaced and that an adapter lead old be made with 10 amp plug on one and and 15 amp socket on the other as long s it had a circuit breaker in line! Think he should stick to ladder safety and leve electrics to the experts

Sounds like a completely sensible suggestion to me

do away with 10 amp sockets and plugs and everything new to be 15 amp , would be another sensible idea, it would only take about 100 years or so to eradicate the 10 amp system

... "Would limiting the power to 10A affect the welder? "

Let me draw you a little parallel scenario re your question above ...

Let us all assume you ( by YOU, I'm refering to "Neg" here) need to breath in say 15 good decent sized breaths to keep you fit healthy and buzzing like any normal healthy bloke ...

Now just imagine I wrap my strong (lifetime of engineering trained) hands around your throat and choke the living f$%k out of you and watch your face turn a bit blue from a lack of that what you suddenly realise is that Oh So Bloody Good Oxygen into your body and a flicker of thought whizzes across your mind (bit like that idea lightbulb thing hehe) would you suddenly compare your imminent state of unconsciousness as being similar to you choking the shit of of you welder ?????????

Perhaps not, well really if you have to ask ...

Blokes and their welders, will it never fricken end ....

No wonder I never ever ran out of work ;)

Just letting a few of you know about welders.

Most of the new ones have electronics control boards in them that need to cool down by use of a internal fan.

Using the 10a plug to 10a breaker to 15a socket is fine but when it trips pulling more than 10a then you start getting welder problems ....not cheap to fix (new board)

You need to look at the welders duty cycle, the info stamped on the weldewr tells ytou this. Most welders out there pull anything between 16a and 32a so obviously a 15A socket wouldnt suffice anyway.

Advice, read the instructions and info on the welder figure out its duty cycle and fit correct plug.

Electrical safety regs points i out the plud needs to be the correct size.

Hi there,
Just to ask something, if you put a 10amp circuit breaker on the lead of the welder and have a 10amp plug would that be accaptable? in that case you are limiting the welder only to 10amp and you can have plugged that in normal 10amp outlet. Thanks

I just replaced a 10A socket in a friends Garage... they put a 10 socket on a welder that said minimum 15A and melted them both.. does that answer your question ??

I recommended he put the welder on trade me, either that or rewire the garage mains (on a two story house).

Not everyone is an electrician or understands why the rules are there....

Picture this $50 adapter supplying a EV with 3.3KW for 6-8 hours continuously.

The adaptor cord from 10 amp plug to a 16 amp cord connector is illegal and should not be used.

The charger plugged into a 16 amp IEC 60309 socket outlet is legal and requires as a minimum of a 30 mA RCD in the switchboard.

A major electric shock risk if the supply and the earthing is not correct for the electric vehicle connection. Some charging systems are smart enough to limit or prevent the start of charging if the electricl connections are not correct.

Went I used to test & tag an industrial workshop about 1 in 10 of their 15A welders had their earth pin ground down to plug into a 10A outlet.

As Steve mentioned above, one of the guys had a 10A plug adaptor with a 10A circuit breaker enclosure going to a 15A female connector so he could plug his welder into it but of course the 10A breaker kept tripping.

Without seeing the Milkshed power circuit it is proabably that you could add a 15A outlet. While you are welding you may not be able to use other appliances on that same power circuit as the breaker may trip. Of course an Electrician would have to confirm this for you.

Original question was over 5 years ago. I think the question about the cow shed is long since moot.
