The flux paste is called Solar Flux type B Its a powder and you mix it with ethanol or rubbing alcohol till its like wet mud then brush it along the back of the seam.

When it dries, weld away, only now make sure that you have enough heat to melt through.

It looks pretty...

If you could please tell us the grade of S.S. i.e. 316L 304L etc. and your application it would...

Hello TMT,

No more smoke so far.

Without it smoking or malfunctioning, the dealer says that he can't fix what isn't broken.

They're decent people, the guy I talked to didn't tell me not to bring it in.
He more or less said that run it and see what...

I understand what you're saying.

I spoke to the electrician at my workplace. He says the outlet should be OK the way it is.

As far as the HF ground is concerned, I wan't to be safe vs. sorry. I do have some halfway decent electronic stuff to consider, like this computer....

Hey guys, just wanted to let you know that I talked to the dealer today.
Turned out to be no big deal. He said the thing's still under warranty so run it.

You're right, it says 230v model right on the cover of the manual and the front label of the unit.

I'll be talking to the dealer or someone at Miller just to be sure I actually need to take it back.(long ride)

Nope, they close at 4:30. I'll get it in to them sometime this week.

I'll let you know how it all turns out.

Send in the electricians!

One way is where the ground can be used as a 125v neutral lets say like for a clothes dryer. If you test the voltage across the two hot wires the...

Neutral ground instead of safety ground

I just found some info about the wiring in this antiquated house.
The recepticle the the welder is connected to is 125v neutral instead of 0v safety ground. If this is wrong I will have someone correct it before I turn the welder on agai...

Hot resistor

Thank you Bulldog, I will end up taking the machine back to have it checked out if that is the only solution.
I did however remove the top cover to see what exactly is getting so hot. It is the resistor labeled WW FXD 100 W 50 OHM. Part # 186468 in the owners manual....

I powered up my brand new machine and after sitting idle for about 3 minutes I could see a light cloud of smoke rising from the back. Everything looks normal except for the smoke. Suggestions??
