Review on 🔧 PGN E71T GS Gasless Steel Welding Tool: Enhanced Industrial Power & Hand Tools by Mario Beckwith

This flux is suitable for small, non-critical jobs. However, I believe sweat porosity is almost inevitable. He doesn't do a good job of protecting. I normally use C75 for mild steel work but have used it as a last resort (no more petrol). I've made several target stands so I wasn't worried about the quality of the weld. I wouldn't use this for anything that preserves life or valuable property as the quality of the weld is poor (porosity).
