YESWELDER Stainless Steel Flux Cored MIG Wire, E308LFC-O

FINALLY someone makes a stainless flux core wire that actually works! I was skeptical because I’ve tried stainless flux in the past that had good reviews, but the stuff was basically unusable. I just picked up a bottle of argon for my tig that was contaminated and I wanted to get my exhaust project done, so I ordered this, and it works flawlessly in my cheap harbor freight 110v Titanium flux core welder. I’d even argue that it welds better than mild steel!!! Very impressive

If your running regular inner shield SWAP your polarity.. Negative to your grounding, and Positive to your torch (like you doing regular Mig with shielding gas) Crank the heat up... ALOT from the manufactures spec. It's going to sound horrible.. I mean god awful!! annnd you'll get a weld that isn't sema quality.. but it works.. good for repairs.. especially when working outdoors.. I really appreciate the self chipping feature.. (As the weld cools.. The slag will start popping off.. as far as 4-5ft) It might startle you if a piece hit's you in you eyeball.. Whatever.. safety squints my be needed? What else.. Didn't like vertical (but dooable) really didn't like upside down! oh, and if you don't clean your stainless good.. your old friend porosity will be showing up.. I could only find 2 okish video's on you tube, and yeswelder does have some info on the product.. It defiantly has it's place.. and it's cheap!

Really impressed, worked great

CAUTION: when a weld cools, the slag will chip off the weld and fly in the air. ALWAYS wear eye protection around the welded area (such as goggles), to prevent slag chips from flying in you eye! There is NO WARNING about this. Nonetheless, it works well, with caveats. I used a Lincoln Weldpak 100 120v welder, wired to electrode poisitive, .035" stainless flux wire, and was able to get plenty of good welds on 16 ga. stainless exhaust pipe. For most welds, I set the heat on "C" and speed at aound 2.6-2.7 (there is a "sweet spot" where it worked the best). For but-joints with a little space between pipes, using "B" and a slower speed worked better, with no edge burn-through. Technique is critical, as you have to go slow and steady, watching the molten pool as you go. Roping of welds is easy to do if the wire speed is too high. Burn-through was not an issue for most joints (for pipe edge-welds, B power was a little better). Stickout was around 1/2" to 3/4" max. Also, ONLY weld in horizontal positions when possible; vertical or upside down welding will cause the pool to run and drip. Splatter is minimal, but the pool can drip if it runs off (not good of course). Weld penetration can be proper with this welder, but it does take getting used to in getting proper penetration and depth, and agian, take your time. I normally have used mild steel flux core, and that is moe foregiving and easier to weld. This Yeswelder wire is less foregiving in that it is easier to mess up if you get in a hurry. But, I really like the shinyness of the welds, once the slag self-chips away. With patience and practice, you can get decent (and excellent) welds with this wire on a a Lincoln 120v Weldpack 100 welder on 16 ga. and thinner pipe!

​I bought this welding wire for a project on a Hot Rod. I put a fully custom stainless steel exhaust on it, and this was the best option to weld it up. It’s a really great product; it welds beautifully with my flux-core welder and leaves a really clean finish. I highly recommend this product! 💯

I'm old enough to think welding stainless required "heli-arc" (today's MIG), but googling found stainless flux-wire like this exists. Worried my basic 120 VAC 100 A Harbor Freight flux-wire welder (no gas) would struggle, since youtubes said stainless requires high heat and a 240 VAC welder. I switched "Max" power and max feed rate (recommended). Project was fixing cracked welds on the 18 awg (50 mil) lower 31" wide oven pan in my Jade Dynasty gas range, between pan and lower stiffener plates. The first welds (top in photo) turned out great (for me), but the middle ones not-great since lingered too long. I had clamped the two plates tight together with cross-beams, but found they had bowed apart from heat, partly from preheating each spot with a propane torch (worried of not enough heat). Can't weld 2 parts unless touching tight, so it even melted thru the stiffener plate edge at places and a bit into the top plate side, which I ground down (2nd photo), plus a crack which might have already been there. My goal was to get rid of bangs as the oven warmed and cooled, which I thought perhaps from the cracked welds. Seemed I was following someone since the detached welds were much uglier than the thin purty welds at the edges (likely factory, perhaps TIG). My oops, but the stainless wire worked great. Youtubers said it popped more than normal steel wire, but I just got comforting sizzling pops. Only got two splatter beads, close-in, matching youtubers who said that despite the loud popping, they got only a few splatter beads which wire-brushed off easy. To avoid them, I had covered the surrounding plate with damp rags.

For the price, this has been a very good buy. The wire feeds consistently, produces a usable stainless weld without shielding gas, and comes on a sturdy spool. Technique and machine settings matter, and flux-core stainless wire leaves slag that must be cleaned. Overall, it is a good value and does the job.

I bought this to replace a roll of generic 308 for exhaust systems and honestly the generic welded better. This wire does not flow, it splatters terribly, and you will find the limits of your welders wire speed and voltage trying to make this wire penetrate. Turn it up and learn to weld in spot welds because this wire is very cold and lacks penetration and you have to set it up for 3/16" to weld 20 gauge. I think my wire speed ended up being 408 in/min at 24.8 volts. Crazy stuff. The spatter is terrible. I thought I forgot how to weld until I changed back to mild steel. Be sure to wear a respirator and only weld in a well ventilated areas so you don't get chromium poisoning.

I could complete the job with this roll of SS flux core wire.

I'm not welding professional by any means however I sure can lay down some nice dimes on stainless with a tig. Having only my mig on hand over the holidays and a project to wrap up I figured why not try this out. Lemme tell ya, it welds BEAUTIFULLY on high grade stainless exhaust pipes! Will be using again for all that under car crap nobody will ever see. Great product for the money

Recomendado

Works as expected

Ran this thru a Hobart ironman 230 I can't imagine running this wire thru a 120 volt welder as I tried several beads to get used to it on 1/8" 304 stainless this wire worked nice with the heat setting on high if you are welding something that has to be leak proof I would highly recommend trying it on a scrap piece of metal first but once you get it set up it will weld very nice
