Welding Tips and Tricks

Did I wire this correctly? Seems like it should be easy but the diagrams with the plug and receptacle were unclear.

10/3 wire. Green between the center posts. White between the two posts marked with the white dot. The white dot in the center of the receptacle is a screw. Black to the unmarked posts. I did check continuity to be sure the marks were right.

I'll feel a lot better to be sure I have not crossed anything. Thanks

Looks right to me.
Makes no difference if the hots are switched.

That's the same setup I'm planning on making. Where did you get the ends? I've been to lowes and home depot but neither sell that 3 prong 30a end. They do have the 50a, its not really an end but a flush mount outlet.

Good to know polarity doesn't matter. Thanks.

I bought the 10/3 wire, plug and receptacle at Ace Hardware.

Just as long as the ground stays the ground, your good to go.

AKWeldshop I love your Quote. So True.

Thank you, I'm proud to have it.

Thanks, I haven't looked at ace yet. I was able to find the 10/3 wire everywhere, cheapest was $1.89 ft.

I started a thread asking about using a setup like the one you made on a 30a dryer circuit. I have to ask, on the 30a 3 prong circuit you will be plugging into is it 2 hots and a ground or 2 hots and a neutral? Lol, I laugh because I'm getting some insisting that its wrong to use a setup like you made if your 30a receptacle is 2 hots and a "neutral" while others saying its fine.

I've done plenty of searching on this and going years back it's always the same, 2 different opinions on it. But I continue to see people making these adapter cords and even see them for sale online.

If you're wire to code, ground and neutral are the same, tied together at your breaker box.

Quite right as stated above. The center terminal is ground/neutral, and the outer posts are L1 and L2, and the orientation doesn't matter.

The advice you're getting from our Aussie members comes from a very strict code, that does not allow an unlicensed person to do what you're doing.

Electricity is dangerous, but not so dangerous as the trade guilds in Australia would have the citizenry believe. I think much of this comes from the jacked-up bullshit many back-country Aussies have managed to kill themselves with before there was a uniform code.

Hold my beer and watch this..... Zapppppp!!!!

I resemble that.

Surprising to hear a comment like that coming from you Steve.

My comments have got nothing to do with code, regulations, going to jail or breaking the law.

My comments are all only based on the dangerous practice of using the Neutral conductor for a ground because of the inherent safety issues if a wiring fault develops. No more, no less.

According to Wikipedia: The United States National Electrical Code states that the feed from the distribution transformer uses a combined neutral and grounding conductor, but within the structure separate neutral and protective earth conductors are used (TN-C-S). The neutral must be connected to earth only on the supply side of the customer's disconnecting switch.

However, feel free to hook up everything however you all wish. Regulations aren't ever made for safety reasons, are they?

Unless you have a lot of proof, the comment 'jacked-up bullshit back-country Aussies' was somewhat unnecessary. And quite disappointing, actually. Especially from you.

You Ought To Know Better. Oh wait, was that an echo?

No more to add.

This circuit does not need a ground because its mounted on a "breadboard"

Under our NEC (National electrical code), remote devices to be hooked up temporarily, as a welding machine dragged to the end of the driveway, the inherent earth ground attached to the neutral line is considered adequate.

If a device is to be permanently installed in a location, as a fixed welder at a bench, then it is to be separately earthed.

That's the code. That's the rules.

I'm not guessing at this, I hold certifications for high-voltage work to 500V.

I can't speak for the intelligence of the rules, only the words.
