porosity

[Azphiks]

Massive porosity on my starts. One mm bubble(or two) on surface, but nickle-size cluster underneath after grinding. Once every 4 rods. ESAB 5mm and 6mm, 7018.
About 1000" of piping production so far. 16" sch60.
Going to try Liquid Air. Don't know what else to do.

Nitrogen gas suggested as a purge for welding a stainless nozzle to heat exchanger. So I thought I would use nitrogen in my torch too. Doesn't work with torch at all. I got nervous and switched the purge to argon before I buggered the job. Rumor is if I keep the gap small and the arc doesn't get...

What is the feature on my Dynasty200 that kills power when I stick my rod or tungsten to the work? Wish my Pro300 has this tech

millermatic 211 autoset failure...help tech people

There is a button on front panel to switch from a spool gun to a mig gun. This may be tripped to the spool gun causing your fault

My brushes are getting near minimum tolerance. Is this an easy home removal/install? There is certainly easy access.

I have a Pro300. My helper used another persons Walter variable speed diegrinder with my machines AC receptacle, she found that when I was welding the AC power was unavailable. My Dewalt grinders will work if I am welding at the same time. Is this normal?

My Pro300 will only idle up if I strike an arc or use AC for tools. Appears as though auto/run switch also used to start and stop machine is malfunctioning? Suggestions?

How does a plasma torch behave with a compressed bottle of oxygen for supplied air?

Is heat build-up the only consideration with regards to a welding machine duty cycle? Can I put the machine in -25 celcius conditions and increase the duty cycle?

If youpick this code, you will have about 65 pages to work with. D1.1 is about 400. Give yourself 3 months to study and should have the whole book memorized. No matter the code, the ticket is the same. One more thing, on site the QC has the best job. Zero authority over the...

Don't let all these pimps fool you. People are entitled to everything they can get, just don't expect to get it where you are. Sit in the bush(keep your job) and stick your name out there. When you find what you want, go and never look back. Helps if you incorporate, but I won't...

There was anti-seize applied to the bolts. A clicker type torque wrench was used

[Azphiks]

Did a torque inspection on about 100 bolts today. All the carbon steel checked out ok. The stainless steel not so. Nearly all out of 30 or so were loose. This was obviously embarrasing for the boilermakers. Now they are tight because I watched them do it. Assuming they did it right the first time,...
