Hello World!
I have purchased a Cheap 90amp ¨ PowerBuild ¨ flux welding machine, and I have try to switch the polarity to electronegative on it but when I opened up I realized it was can of warms, so I put it back together and did not mess with it. I am still welding terribly bad wasting my flux cord, I am just a hobbyist but never the less I am concerned about penetration on on the work piece ,, I wonder if someone has the same Brand that I do (PowerBuild ), now I have research YouTube videos and the like but my brand of machine is not depicted on any video or explanation. Any Help will be greatly appreciated.
Pura Vida!!

Most dedicated flux core boxes that I’ve seen are already DCEN.

If you can describe the material thickness, joint type, and maybe post a picture of your weld someone can likely offer good advice.

good to hear your concerned about penetration and the quality of your welds. 8-)

the fix is pretty simple, throw it on the rubbish bin.
then go buy a basic inverter stick welder and learn to weld with that.
once your good with that, if you still want/need a mig, go get a reasonable mig.
mig welder for bigger projects and stick for small or outdoors stuff.

the cheap fluxcore machines are just the crappiest thing they can make. they are frustrating to use, hard to learn with if you have to fight the machine all the time as they have such big limitations and you will simply out grow it in days.
stick welding is still the best way to learn and are always useful machines.

friends don't let friends buy flux core welders :D

Sometimes hard truth hurts! But it’s still true! You will waste more money getting that machine to run than just getting a better one now. I don’t necessarily mean a bigger (more amperage one) just a better quality one.
