Yeah, a couple of things. Set the amperage way low, and also set the wire speed low. Practice on some scrap tubing to fine tune. Its easier with gas sheilded than flux core becuase the gas coola the weld a bit. Start with the amps low and gradually bring them up until the wire doesnt stick and you can maintain a short arc. Long arcs create moe heat. You cant do much at the time. You can also stitch weld with plenty of time to cool
