![]() In fact, this whole weldingweb thing is a big help to us self-taught novices. Now, I am going to try the better wires to improve the spatter. I am able to get satisfactory welds every time. Even if I layoff welding for months, I warm up with a few soup can lids to refresh the technique. It takes no more than 4 or 5 cans to get the technique under control. Using a special "can-opener" (for soup or beans etc.) that has a horizontal blade that makes a clean-edge on the soup can lid, I weld the lid back onto the can (empty of course). So then I fell into a practice session to see if I could improve the looks of weld. It does work on thin EMT tubing, a little messy but solid welds. Well, after switching to DC stick welding, I got the hang of it, and went back to the HF flux core machine. I figured it was my fault, being a newbe. I never thought the HF wire was the problem. My experience with early design 90 amp flux-core welder was just like you said. I can't think of any other reason for that sudden huge number of them as 'as new - open box' on Ebay. So nearly all of that batch immediately became customer returns. I suspect HF included the lowest quality of flux wire on that earlier batch of welders, and that mistake doomed that entire earlier batch of welders. Then I noticed a large number of them on Ebay including a professional liquidator listing many.Ī year later I bought the same model and it welded ok. I've mentioned this before but Tapwelder may not have seen it: My first flux welder was a blue Harbor Freight 90a AC 'Mig-100' 15 years ago. And the customer can only judge quality in advance, by the manufacturer's reputation. So there can be wide differences between brands. While the E71T-GS spec shown on most brands, means whatever the manufacturer considers suitable. So the Hobart should in theory run the same as Lincoln. I just noticed that the Lincoln and Hobart flux wires are both "E71T-11, AWS 5.20" specified alloy. I could see the puddle but not the edges of puddle. The second is a.butt joining 2 1/16" steel tubes. Veritcal up capping a 6013 bead on 1/8" used machine setting deom.the panel. I thought I could use for tacking steel for gang cutting, but nope. I thought if was because my contact tip was to close as it was shorting across spatter, but it happened with a 1 in space. The only issue with the welder is it pisses our occasionally. I could not seen the edges of the puddle. I cannot believe i used to weld with this stuff. It has a jog switch inside but that was discovered after I paid attention the instructions. Must of that time was spent feeding the wire. While Hobart MIG wire is made from carbon steel, Lincoln wire is made from stainless steel and coated using copper. The materials used to manufacture these MIG wires are also different. Probably could but o have no use for this process. Lincoln MIG wires are therefore suitable for applications such as automotive repair, petrochemical, transportation, marine, and power generation. Thought i might be able to use it instead of stick for outside installs. Have not welded with fluxcore on about 15 yrs.
