You don't need any of that stuff. A Miller-Matic 135 with .035 flux cored will do just as good.

.035 flux cored takes about as much clean up as stick. More people around here can weld stick better than wire.

No, just many people are better at stick. either from ship work or usually because they come from field work.

Kinda hard to run a mig with a 30 mph cross wind.

I think the skill required to make a weld look that good is simply lost on a lot of people.

I'm about as ignorant on stick welding as the day is long. I'm hoping to buy some wire or TIG based equipment soon and start learning. I'll never be good enough to be a "pro" but hopefully I can get the results I want.

all it take to be a pro is someone to pay you to do it.

Making a stick weld look good doesn't make it a good weld, but it does show the how steady of a hand the welder has.

Never knocked the way you guys weld.
Its the way the Millwrights seem to claim EVERYTHING. Including PIPE.

3/16 is for ironworkers laying flat beads anyways.
I have used 3/16 and 5/32 on pipe in position. I have used 1/4 on roll outs on 2 inch pipe. We had to make the inches. I just finished a job 2.5 inch and 4 inch pipe 90 10 copper nickel with tig.

chaikwa.

When we do microwire it from a Miller 304 cc/cv and a wire feeder with .050 wire.
NOT a 110 volt mig wire machine rated at 20% duty cycle and a MAX of 135 amps.
That weld wouldnt even pass a bend test with that machine.

Xrayed for a refinery, or nuke?

I have ran ALOT of big rod for boiler rooms, gas lines, steam piping and hydraulic lines.
BUT NEVER for x-rays.
The bigger the rod the more porosity it holds.

I have been around MANY oldtimers and they NEVER use anything over 5/32 for x-rays.

Yes, I know! I was being sarcastic... as usual.

Man, .050 wire. I don't think I could run that even off my 400 amp machine on the truck. That's some BIG stuff! I run some .045 occasionally, but I have to be welding on something 3/4" or bigger to justify it.

When I was doing a lot of shop work back east, I think I had the same machine you were referring to. I don't remember the model number but I DO know it was an 'XT' power source that would automatically adjust to any voltage and phase you fed it. That was running a wire feeder and we did a lot of spray transfer with it. Very nice machine and I miss it.

Chaikwa's jealous.....don't let him fool ya

nice to see a weld with stick work. very nice penetration at even temp. good eyes too, not just steady hand..

I live in Dansville, NY when they use to make the boilers for the nuclear subs, huge factory, etc. they left for other world locations. but out of the 6,000 folks that worked there, every one of them had to weld and certify.
they use dynamite to bend the panels, and fittings 5 inch to 42inch. now the place does wind turbine assembly, diesel engine locomotive rebuilds and machines more fittings for special production orders (oil rigs i believe). Believe me, there are no broken parts anywhere in the town..LOL

I agree with T RAD, very handy to work on your own equipment. we build what we need here, fix the farmer's field work, and play around with metals we will never see again. fun to learn but expensive to screw up.

more power to ya DMAN!! America runs because of guys like you!!!have a cold one on us!

Heidi in NY (stick is where it's at!!!)
