Guys, this is my first welding machine. I learned to cook on it with the help of YouTube. Troika cooked at 120 amps. At 125 amperes, I reaped a professional pipe deuce calmly. I worked for two weeks every day, nothing broke, nothing burned out. The device is excellent, I have already recommended it to all my friends. I bought here, as it turned out to be cheaper than our Chinese friends.
