Getting ready to do this myself, I've watched A LOT of videos in preparation, none have explained it like you have with flux/no flux/ no gas, heat, and tips - Best video I've seen, hands down!
As someone who's currently restoring a car, all the horror stories I've heard, of how you shouldn't use flux core for bodywork, because it's to hot , it's dirty, you'll just burn through... bla bla bla... Yes you can, but it takes patience, practice, and alot of preparation. 90% of the welding I've done, has been with a cheap fluxcore welder. Even after I bought a MIG welder with gas.
Hi there, I've tried to weld a rear quarter panel on my friends car and I was using flux core, I used the lowest settings on my machine and it still burnt through I prepped the steel quite good and it still burned through, any advice ?
I look forward to seeing your video on flux core welding. I'll definitely will be upgrading to a Co2 gas mig as the metal on my project car is very thin and hopefully it'll cut down on any distortion. Cheers
“Doesn’t matter who makes them it’s basically a transformer with a wire feed”. Absolutely I’ve seen third world countries use a repurposed transformer running great beads on 6013 drag rods. Appreciate your content as it is informative. Thanks
Great video, well explained. I have an inverter flux core welder that works very well on steel, I’m reluctant to us it on body panels but maybe I’ll give it a go after watching your success.
I've done this exact same thing, and issue is less than 6 months later it starts rusting from the inside out. I stopped using any filler, and have been taking the time to get it perfect so no filler needed. You want to talk about pita. Lol. Shoot me in the face
Well it's unfortunate that it rusted out after 6 months. This repair was done 2 1/2 years ago and holding strong. Thanks for watching. Much appreciated.
Now that it's coming back to me the repair I made was on an old half rotted out Nissan murano. It didn't have rust free metal to patch to. It wasn't worth repairing, but I wanted the practice. Great video. Thank you @@swc-diygarage
Huhh, did not think about the polarity making the melting process different. But of course.. Thanks! I have struggled with flux core welding rust on cars. Like really struggled. Especially with burn through. But I suspect TIG would be even worse.
TIG and rust usually doesn't work out. The rust tends to explode contaminating the tungsten. Truly all you can do is get rid of all the rust you can. Thanks for watching much appreciated.
fiberglass will seal it making it water tight on the outside. water should never be getting to the inside. I spray the inside with under coating oil once the part is finished and painted.
The set up material needs to be the same as the repair. Then adjust heat and wire speed. It's important to maintain the same amount of wire stick out and distance from the work piece. Small changes can have a drastic effect.
I've never had problems with pinholes because i apply fiberglass to seal it up. I think alot of people don't treat the inside with some kind of under coating once the job is complete.
Give me confidence to weld with my Mastercraft again but this time on thinner parts like pannel ! My mastectaft is mig and flux core ,should I put gas on it is it expensive to use ? I will cool it down with wet tissue has I haven't got air compressor but still ! You made my evening I go to sleep thanks Men ! Pierre from Quebec .❤
Gas mig is definitely better than flux core. To purchase a small bottle is around $300 plus take it and have filled. You could possibly rent one for a short-term. You can use cold water and a sponge to cool your welds. Thank for watching.
Thank you. They were no 20 gauge here last summer my projects, so I had to use 24 and 22 gauge. It was thin for my Mastercraft but not to bad for my Forney 261. Thanks alot for your video's
