Why TIG Welding is Recommended in DCEN (DC–VE) Polarity? TIG welding polarity selection has a direct impact on heat distribution, weld quality, penetration, and electrode life. Among all polarities, DCEN is most commonly recommended for steels and many alloys. Visit weldfabworld.com ⚡ DCEN (Direct Current Electrode Negative / DC–VE) ✔ Most Preferred Polarity •Heat Distribution: ➤ 70% at Workpiece | 30% at Electrode •Weld Profile: ➤ Deep & Narrow Penetration •Cathodic Cleaning: ➤ ❌ Not Available

Trying to find the perfect tungsten electrode for the TIG weld you’re planning can seem like a bit of a mission. There are quite a few tungsten types on the market, and every single one of them does something different, even if it’s just slightly. We’ve broken it down into a quick and easy guide with the Australian standard colours, so you can find the tungsten you need hassle-free. https://unimig.com.au/tig-tungsten-selection-guide/ | UNIMIG
