A colourless, odourless and non-flammable gas mixture of 75% Argon and 25% Carbon dioxide can play a great role as a shielding gas. It protects the electrode, metal basin and heated metal near the welding seam from the ambient air while also facilitating the welding process and improving welding characteristics. This mixture is universal and suitable for welding low-treated and stainless steel.
The use of this mixture helps you achieve a stronger welding seam since the metal is casted more evenly and internal tensions of welding seam are lower. The obtained seam is lower than in case of welding with carbon dioxide. When using this mixture, the quality is maintained and welding process is faster.
