I'm surprised it works great for the price. I have never used a flux core and could work with it immediately. You can use 110V or 220V which makes it even more versatile. also the reels can be flipped on one side 1mm(0.039), 0.9mm(0.035), 0.8mm(0.030), can hold 0.5kg and 1.0kg wires. Good quality pistol.
