If the OP had known Outershield 71M is flux-cored wire and not mentioned Mig wire, the counter guy might have brought him Outershield 71M which is the same type of wire as Esab Dual-Shield which is also flux-cored wire. The counter guy may have just been confirming what he wanted. The OP saying no to flux-core and wanting Dual-Shield is another confusing and contradictory statement. People are always complaining about how the parts guys don't know anything or how to look anything up and always get the order wrong etc, etc. Well in this case the customer was the cause of the confusion. I deal with this stuff everyday and just like the counter guy we aren't mind readers that can know exactly what the customer wants when the customer is giving confusing details. I've had requests asking for .035" contact tips or pictures of nozzles with no numbers or any markings and am supposed to just know what make and model gun they go on. Sometimes I'll get a part number and they say it's for a different brand than it actually is. Sometimes it's easy to figure out and sometimes not. It's not always the person trying to help you that is causing the confusion. I guess because I've been there I'm sticking up for the counter guy.

I know what "Dual Shield" is. Like Kleenex is "tissue". By the way, tissue has so many meanings, Kleenex is more descriptive. Several manufacturers offer a product very similar to Dual Shield.

I get irritated when people refer to 110 or 220 in electricity. If my home has 220 Volts, something is wrong. In this country, and elsewhere we hope for 240 Volts, we slice the sandwich in half, so we use 120 Volts.

Nonetheless, I've never heard a court decision that stuffed wire isn't metal. Directly translated; MIG stands for Metal Inert Gas. I guess we need MFCIG, or something more clever than I was qualified to come up with.

Until then, MIG works for Gas Shielded Flux Core. And yes it is wonderful, except for those worm tracks.

Technically, I believe Gas Shielded Flux Core welding is MAG, not MIG. Isn't CO2 an active gas?:laughing: Even though I've read plenty of sites that list it as MIG welding.

MAG is a term more used in Europe when using CO2 shielding with solid wire( MIG/MAG). I really think the confusion comes because there are some small wire feed machines that they refer to as flux-core only. In this case they mean self-shielded flux-core like Innershield. Some of these machines can be converted to Mig using shielding gas. A lot of people don't realize there is also gas shielded flux-core (dual-shield). Perhaps a better way to note the differences is by using AWS designations. GMAW (gas metal arc welding) refers to Mig (or metal-core), FCAW (flux-core arc welding) refers to flux-core but can be self-shielded or gas shielded. It is common to do a Mig root pass with solid wire and then do the fill and cap with flux-core. A good reason for a dual wire feeder. Metal-core is considered GMAW because there isn't flux per say in the wire and no slag is left on the weld. Some refer to it as MCAW for clarification but it's not an official designation. Gas shielded flux-core can use mix gas or CO2 depending on the wire.

It is a carry over from when appliances were 110 and 220 volts.

At the cabin the power was so weak the only way the black and white TV would work is with a Buck/Boost transformer...

I might not be a CWI, but I do know how to read people. And the counter guy did't know what he was doing.

A good counter guy should be able to set up, run and train on anything in the store. Also should be able to assist in filler metal selections. If he was unsure, he could have at least asked what the application was and at least offered up a couple of options. That's how it was when I was a counter guy in the 80's and 90's. Now days gas is king and with good reason, Very low margins on hardgoods due to competition on the web.

A lot of the problem is lack of training or not wanting to pay to have someone with more knowledge. The counter guy in this case may have been unsure so when Outershield 71M Mig was mentioned asking if the customer meant flux-core was a legitimate question. Maybe they didn't have Outershield 71M but had something similar. With all the new technology in welding customer service seems to have taken a nose dive. I don't know of any welding supplies that have a demo room anymore. Lincoln used to have a shop here where you could try out any of their machines and filler metals. Miller has facility where you can try out machines but you have to set it up with the rep. I think for home owners and hobbyists a demo room would be a great way to help sell more machines and show the differences between them.

110. 115, 120 and 220, 230, 240 have all been used and 99% of the time are interchangeable. Most welding machines allow for 10% line compensation so no problem.

I'm in my 49th year as an electrician in VT. 240 at the transformer has been goal voltage for power companies all my life, and I believe before. Among US built, or devices built for USA consumption, I doubt anyone living was alive when 110 volts was design source. Edison in the 1880 era used 90 Volts as his standard. You are correct, voluntary compliance says a motor sold for use in the USA shall tolerate 10% + or -. Motors designed for 230 volts will then run on 207 - 253 volts. 208 volt systems can then power motors designed for 230, but delivering power to them with as little voltage loss as possible is expensive.

Motors run cooler at or 10% above design voltage than at lower than designed. As voltage decreases, torque falls dramatically, magnetic choke effect diminishes, and BTUs skyrocket, sometimes exceeding the cooling system's capacity.

While 110. 115, 120 and 220, 230, 240 have all been used, and are common language, I'd sure rather have 240 than 220.
