Anybody ever build a frame with one of these HF flux welders? I recently picked up a Chicago 125 Flux harbor freight welder for $70 on OfferUp. Only 3 weeks old. It already had an upgraded ground clamp and new wire. Been welding on some scrap metal to practice, and also welded a crack on my kart's frame, but I'm just wondering if this welder would be good enough to weld together a whole frame with.

Best recommendation I can make it so head over to youtube, and pull up Weld.com's videos on flux core welding. Watch them, then practice, practice, practice...

Also, lots of people overlook the importance of getting the metal they're welding CLEAN. I say, it needs to be CLEAN!

I'd recommend using the Hobart Handler 140. It's pretty cheap and easy to use. You can flux core. Here is a review and tutorial to weld flux core with this hobart welder:

I used a similar Century flux core welder to make a battery platform for the back of my kart and it has held the 49lb battery with no problems even with extremely rough riding. I also made a gokart hitch to pull my kids in their bike trailer (slowly), fixed and strengthened the front assembly for an electric jeep, and built a strong trellis for a misfit rose bush that destroyed the previous store-bought trellis. I found that dialing the settings a bit lower than suggested worked best (6/6). I don't doubt the strength of the welds; they can just require a bit of cleanup with occasional spatter.
