Welding Tips and Tricks

I wanted to find out some info from you guys in the know.

The Miller Diversion 180 can run both 115v or 230v input.. I was chatting to someone about them and he mentioned the following:

When the US say "220V single phase" they mean 2x110V active wires 180º out of phase and no neutral. With that extra active wire they can carry more current.

Is this the case with the Diversion 180??

Warranties aside, Would it be possible to change the plug/wiring so it only ran on 230v and with an Australian plug??

I couldn't find any documentation on Miller's website if this is the case..

Thanks in advance!!

Are you thinking about buying one from the US? If so, I'm pretty sure it's not that simple. Plus, most of the Miller stuff can be bought through welding.com.au already set up for Australia.

No its already here in aus 2nd hand... I didn't think WIA sold them as its not on their site...

Maybe they don't, but their catalogs are a bit dodgy (never seem to have everything) but there would be many comparable or better machines available here.

Just had a looky loo at the site, You are right, clearly they don't think there is a market here, I know the cigweld weld skill has built in settings, as does one of the everlast models.

Honestly, this is a question best left for Miller. I would think there would be no problems but they would be the best help, in my opinion.

There "should" be no issue here, as most Miller product manuals spec 50/60 Hz in their performance charts.

You'll have connections for L1, L2, and common/ground/earth, which will match your house wire, and all "should" be well.

Read the data plate on the machine or the manual. If it has specs for 50 Hz, you're golden, and hook it up.

My thoughts as well.

Also, the Miller tech email gets fast response - you may want to shoot the question to them to be sure.

People drive me crazy with all the out of phase nonsense with 230 volt power. In both countries a home gets one transformer that might be shared with neighbors. The transformer has two coils of conductor, and an iron core. The primary creates a magnetic field when high voltage is applied to the two ends of this primary coil. In some countries 50 cycle is used, in others 60 is used. As the flow reverses, voltage falls to zero, it's the collapse of the magnetic field that makes it wash over the secondary winding inducing voltage in the secondary.

The secondary coil picks up the reversing magnetic field, which induces voltage in it. It's pretty universal that for home use the secondary voltage will be close to 230 volts. In USA 240 is the goal voltage at the transformer. Many countries use only 230 volt power. USA places a connection in the middle of this secondary coil so we can use half the coil to produce half voltage. Here in USA we ground this center tap in the winding, there they ground one end of the coil. This has little effect in the machines you will use.

Q: Will it work on 230, or 220 volts? A: Yes.

Q: Will it work on 50 HZ power supply? A: I don't know. The nameplate may say.

Being "out of phase" would require more than one phase.
