ПОЛЯРНІСТЬ при зварюванні тонкого металу. Чи є різниця між зворотньою та прямою полярністю?

50 Shades of Polarity — Which One Should You Use? Hashtags: #welding #WeldingPolarity #ReversePolarity #StraightPolarity #ThinMetalWelding Description: In this video, we explore what reverse and straight polarity really mean, how polarity affects penetration, spatter, arc stability, and—most importantly—which polarity you should choose when welding thin metal with a stick electrode (SMAW/MMA). I'll show you practical welding examples using both types of polarity so you can clearly see the difference for yourself. Whether you're a beginner or an experienced welder, be sure to watch until the end—many people get this nuance wrong! In this video, you'll learn: • What polarity means in manual arc welding • How the arc changes with reverse and straight polarity • Which is better for thin metal • When polarity doesn’t really matter Don’t forget to support the channel: 👍 Like the video! 💬 Leave a comment – which polarity do you use? 📌 Subscribe so you don’t miss upcoming tests and comparisons!
