![]() Mat-C 02:04, (UTC) Reply Remember, we just want the history of GMAW, not welding in general. I can take a nice pic of my little 150 Amp welder if that's any use? Only slight issue might be it's an unusual make (Ferm/Sealey). Notes on usages in industries (eg auto).General differences (pros/cons) with tig/oxy-acetylene/etc.Preceding unsigned comment added by 75.107.25.196 ( talk) 02:37, 28 October 2016 (UTC) Reply Also Provided that it is switchable from DCEN to DCEP, a gas-shielded wire-feed machine may also be used for flux-cored wire. DCEP, or DC Electrode Positive, makes the welding wire into the positively-charged anode, which is the hotter side of the arc. The polarity can be reversed only when special emissive-coated electrode wires are used, but since these are not popular, a negatively charged electrode is rarely employed.Īnd Section: Flux-Cored Wire-Fed so these gasless machines operate as DCEP, rather than the DCEN usually used for GMAW to give deeper penetration. Since the anode tends to have a greater heat concentration, this results in faster melting of the feed wire, which increases weld penetration and welding speed. Resolve conflicting anode/Electrode electrical polarities, between Section: Power Supply electrode is generally positively charged.Please, add to this list if you think something is missing!
