NEMA 5-15R to Australia (AS3112???) Plug

[BeverlyHillsCop]

Hey guys,

I've managed to get hold of a new Miller Tig Welder, It uses a NEMA 5-15R plug, is there an adapter plug I can get to convert it from the NEMA 5-15R American Standard Plug to our Australian plug? (I assume 15A plug) ?? Can't change the actual plug on the welder cos it uses those Miller Multi Voltage Plug system..

Something like this, but I assume needs to be 15A?

You could buy one of these

And with a bit of cable you'd have an adapter / extension lead to suit.

Also, are you sure there is anything actually done voltage wise in the Miller plug? I'd be surprised if it doesn't voltage correct inside the welder.

Hmmm those links u posted may be the trick!! thanks heaps!!
I doubt it does anything voltage wise either, just allows u to switch between 115v and 230v plugs just using their adapters.. i just dont wanna cut plugs etc off a brand new machine

why not get a extension cord to suit from the US and chop the end of and change it to suit aus powerpoints

The standard North American plug is (NEMA 5-15R) is 15A @ 115/120V, that means the maximum you can pull out of a NMEA 5-15R socket is ~1800 watts. If the Miller is a true multi-voltage device, then a standard AU 240V 10A plug is plenty for the expected less than 1800W the welder should draw.

I'd be surprised if there was anything fancy in the plug on the miller and it'll be nothing but a standard US domestic plug. My guess is that the voltage conversion is done in the welder itself (it's probably an inverter welder that doesn't care about input voltage), but if you want to be sure and do it simply, just get a standard traveler adapter that will convert an earthed 5-15R US socket to a standard 10A AU plug. You can pick the traveler adapters up almost anywhere.

What's the style of the supplied 230V US plug. I can probably get you the right 230V rated socket to use to make a suitable extension cord.



My 225A Lincoln stick welder uses a NMEA 6-50, but it could get away with a 6-30, but Lincoln has standardized on 6-50 plugs on their 230V range.
