The Lincoln website says it's an all position general fabrication wire, and mentions sheet metal as a possible application. What are they taking exception to, the downhill? The galvanized?

Welcome, Vileng. I googled but didn't find any welding company names similar to "Quality Control". With a name like "CUT 50" is your machine a plasma cutter or a welder?

I saw the "F" designation on the torch name and looked it up... and see there are "F", "V", and "FV" flavors. I'm guessing "F" is for flex head, but what are V and FV?

Assuming it's operational and including the cylinder it sounds like a good deal! When you visit keep an eye out for torches, regulator, cables, tungsten, filler, etc.

If you're thinking of building a positioner, take a look at this project: http://weldingweb.com/showthread.php?48154-welding-clamps It can really expand your thinking when you realize it's all common parts joined to create an uncommon result. The holes for the ball clamps would be a bit tricky for s...

This is a link to claz.org, which can search Craig's List nationally if you leave the location out of the search parameter. This shows what owners want for the machine, not what they get for the machine. You can also search ebay for closed auctions and see what the sale price was. http://claz.org/cl...

I've read that Airco welders are re-labeled Miller or Esab machines (just as Kenmore washers are made by other manufacturers for Sears and re-labeled), so the quality is there. Are you looking at one, considering a purchase? I can't speak to value, but those transformer machines are very durable. Ab...

but every once in a while when the geometry of a part I am working with is a bit of a pickle...The arc keeps wandering away from the bit I want to form the bead, the way I hold the torch or the settings seem to make no difference. Is it possible the odd geometry of the workpiece is causing your arc...

I bought a flap wheel designed for aluminum to cut through the oxide layer. Then an acetone wipedown to remove any surface crud.

+1 to Mick's response: you can find all the bits at a hardware store, plus the looking and finding will be part of the fun. The other aspect of building your own is designing to your own specs. In the original photo the hinge mechanism (that you subsequently drew up) *looks* like it's an inch thick,...

Just saw the helmet video- I predict a spike in sales of Lincoln's "Viking" model!

Willkommen im Forum! Ich bin sicher, dass Sie Ihr Englisch ist besser als mein Deutsch!

I got a hit here: it specifically mentions your r-2278 http://www.regulatortorchrepair.com/store.php/products/r412-purox-regulator-repair-kit I got a hit when I searched on the r-2279 but this link doesn't mention the r-2279 specifically. http://www.regulatortorchrepair.com/store.php/products/r-207-...

Was the DWI welder getting $25 per hour on the payroll? If yes then the employer was likely providing a machine, consumables, and argon, not to mention a workspace, lights, fixtures, etc.

Must be a good machine: they're still making them, for sale at $700 so you did well at $80!

Not bad for your first go, keep at it!

That makes me wonder if pedals are shipped in pieces on purpose.

Depending on your time zone you may be a proud new owner... how'd it go?

Welcome, Tooms! If it's helpful, this calculator can narrow down the accessories (tungsten and cup sizes) and filler rod size for different weld scenarios.

The good thing about transformer welders is that they are so simple, they're usually bullet proof. As long as the fan is working, and animals haven't destroyed the internal wiring it should be good to go. I haven't priced them but I took a quick look on ebay's closed auctions (to find the deal's clo...

If you contact Everlast about damaged or missing parts they'll get the parts to you. I received an Everlast box and the foot pedal had come apart- can't figure out how a box inside a box gets FUBARred when the outside box is OK. I was able to put the pedal back together, no harm no foul, but on anot...

Try a google search on "foil HVAC tape", or check out this link at Home Deep: aluminum, $4 for about 10 yards. Would this do the trick? http://www.homedepot.com/p/Nashua-Tape-1-89-in-x-9-8-yds-Multi-Purpose-HVAC-Foil-Tape-1198777/100187909#specifications I recall one of Jody's videos featu...

Sure is a beautiful day in your neighborhood!

In photo #4, what is the purpose of the 2" (or so) welds that are perpendicular to the main weld joint?

The Miller site... http://www.millerwelds.com/service/ownersmanuals.php?model ... lists 33 different Maxstar models. The manuals should have an "input requirements" section and will give you a starting point for when the electrician arrives. But the other responses about installing a 50 am...
