Wasted money. I took it for a test for a semi-automatic welding machine. Well, there is a lot of splashes, the slag is very hard, you can’t beat it off with a hammer. I thought that I bought a bad semi-automatic welding machine (Aurora Overman 185). As a result, I bought a cylinder with a welding mixture and a copper-plated wire from the same DEKA company (also cheap). I cook and in my heart I am calm for the welding semiautomatic device. Sorry for the quality of the seam, I'm learning (photo 2). Well, in photo 1 is the result of the work of the DEKA flux-cored wire. What a blessing that I took only 1 kg of it.
To provide a more engaging experience, I have added some photos to my review.
