Well, I would think something like that would nail a diagnosis for someone who knows those machines. Now, where are they?

Have you tried AC stick welding with it?
My first thought is to verify that it's providing AC current, and how much. Do you have a clamp-type ammeter?
You tried every setting, and you are getting all kinds of bad results. But what we want to know is which setting is giving...Last edited by MAC702; Yesterday, 09:26 AM.Leave a comment:

When you switched from GMAW to FCAW, did you change polarity?
When you ask a question here, you need to tell us all the things we would know by looking at your machine. All your settings. What brand and type of wire you are using, etc. What are you welding on, and how was it prepped?...Leave a comment:

How do you know that it DOES have power at the receptacles for those first few seconds? That's the part that sounds weird.Leave a comment:

It's probably a DC motor. You'll need a DC voltage setting on the meter.Leave a comment:

What is your diagnostic experience? What meter are you using, what setting is it on, and how are you testing the two wires going to the motor?Leave a comment:

I'll bet it won't trip in the next 40 years, either!Leave a comment:

Wish I could help. Where are you in PNG? I was in Port Moresby for two years doing welding and electrical work.
I'm hoping it's an easy issue to diagnose, though, with a good running engine, and none of the outputs.Leave a comment:

Perfectly safe and meets the National Electric Code Article 630. No change in plug necessary....Leave a comment:

One thing to add is that modern breakers are both thermal and magnetic trip. Overloading a circuit will cause the temp rise that trips the breaker. The higher the current, the faster this happens.
But under a dead short condition, the extremely high current (on the order of tens of thousands...Leave a comment:

I've been away for a month, Sam, so some of these may have been solved or addressed, but I'll make what observations I can as I see something.
We don't want to say that breakers can clear "any ground fault." They are overcurrent protection devices. There can be ground faults...Leave a comment:

Depends on what you want to build with it.
Ironically, we have Italian welding machines imported here that are/were considered quite good: Forney. Maybe look into their lineup. Miller even used to import their machines to put their label on it, when Forney was a step ahead in lightweight...Leave a comment:

You left out the most important piece of information.
What was the joint design?Leave a comment:

Yes, and it probably means that recommendation is for the FCAW process and will require wire that is rated for multiple passes and an experienced technique.
There is no reason the OP is making us guess. He should have just told us exactly what machine he was looking at....Leave a comment:

FCAW is going to be a challenge on materials that thin. That's why it's not on the chart. Turn it lower than the lowest recommended setting, and experiment with your technique.
But it should be said that you're asking the machine to do more than it's designed to do well. You'll be better...Leave a comment:

FWIW, even though the thread pitch and length is quite different, Lincoln style tips for their similar small machines will work perfectly fine in Miller/Hobart machines. They are sometimes easier to find.Leave a comment:

A basic welding machine is an electrical AC transformer that converts your 240 VAC supply voltage to a much lower voltage, but being able to use the power (wattage) available to convert that to a high amperage which is the heat the does the work.
Example:
You have a 240 VAC...Leave a comment:
