Diversion 165 Problem "Poped then smoked"

[ryanjones2150]

If your tungsten is discolored after welding, you should probably increase the post-flow.

I just noticed that the tungsten has a reddish color to it. Couple days ago it was bluish.

PLS Explain...??

1.5% Gold Lanthanated 3/32" tapered Dow
125 Amps

2% Lanth is better...................

Here are a couple of Tungsten comparisons

I got the 250 going. I don't have it moved to my shop yet but I basically have it moved so I can finish a project that is two weeks a delayed.

my welds are similar to what they were before. But, I think I'm not operating the welder correctly. My tungsten is splitting down the tip. Other times is just flat out cooks away really quick.

any suggestions?

What Tungsten...??

You want..2% Lanthanated (Blue) Tungsten... Taper ground...

??? what size..??? Amperage...??......

Sounds like you are running 2% Thoriated (RED).... that does NOT like AC

+1. Thanks for steering us back. :-)

I worry about people getting hurt by some inadvertant act causing mayhem on their person or property....

a little bit of knowledge can be a dangerous thing........misunderstood or misapplied

[Aeronca41]

They should call a local licensed electrician....for their particular situation...

otherwise the danger and liability are too great..... it will be money well spent

We have gotten petty far off topic....(AND Best Practices.....)

I would like to hear how GGODWIN is doing with his new SYNC 250

Thank you Aeronca41 and H80N for the information.

The fact that electrical fires happen was the reason to ask for the correct size breaker to supply a welder at less than max amps, so we can give good advice in the future. When the O-P asked if he could run a Dialarc H-F off a dryer outlet, Ryan’s answer was “NO”, and all I could say was the O-M requires a 150 amp breaker (for 310 amp output). Neither of us could recommend a breaker size for 250 amp output.

With information like this, us junior members can help others with the basic questions, leaving you more experienced senior members to tackle the really difficult questions.

It is far more common than a lot of people think for a federal pacific breaker panel to burn someone's house down. I even have a class I teach here about these miniature weapons of mass destruction. And can you believe the ace hardware here sells replacement breakers for those panels? What a shame.

[Aeronca41]

FPE breakers are bad bad. Had another house fire last shift caused from the failure of an FPE product. Got me and my FF burned in that fire too. If you have an FPE panel, do yourself a favor and change that mammerjammer out.

Scary! I try to take.every opportunity to warn people about those things, so they don't need guys like you and your team showing up at their house. Your last your last shift is proof that there is still a need for warnings.

Personal opinion only-others may have different ideas. If I was planning on 90 amps in a welding application I might go with a breaker the next standard size over 100 A, or just go with 100. Check the link below for typical breaker trip curves-they are only instantaneous devices under some conditions.

You can see from the graph on page 2 that depending on severity, overloads may be tolerated for considerable periods of time (unless you happen to have old FPE breakers; they will tolerate huge overloads almost indefinitely including after the house fire has already started).

If this was a general household circuit, code only allows for design load of 80% of the circuit ampacity. Art 630 for welders makes the special case.
