A specially formulated Argon, Carbon Dioxide and oxygen gas mix (often referred to s a tri-mix or argon shield) which can be used in a number of welding positions. The name comes from the 15% carbon dioxide content; the extra CO2 gives this gas the capability of MIG welding carbon steels up to 18mm in thickness. Welders will experience good arc stability and a broad heat which is due in part to the 2% oxygen content. The combined benefits of good welding performance and minimal spatter make it very popular among the agricultural, on-site and mobile welding market. The wide operating range makes Hobbyweld 15 the best choice for structural steel work, medium gauge plate and general fabrication.
