I first tried Hot Max on my 110 stick welder, they were the only sticks that could weld thicker gauge steel cleanly! So I tried their flux core. My cheap 110 cored wire welder now welds like its higher end welder. I've tried 3 other grades, this is the only grade I've used that can weld cleanly and penetrate without overheating and warping the steel without a high end welder! I was ready to throw my welder in the trash before the hot max. Less heat, weld like a master.
