Reasons to Use C25 Shielding Gas When MIG Welding Mild Steel
C25 shielding gas is a gas blend, one of several that we carry at Eureka Oxygen. It is available in the smaller gas cylinder sizes, perfect when you're doing the odd or occasional weld around the home or ranch. Beginner welders using MIG welders utilize their 120-volt circuit.
Argon is an inert gas and much less reactive than carbon dioxide. It provides a cleaner arc start and a smother melt of the welding wire into the base metals, as well as working well at lower voltages. This means it is better for thinner mild steel and low carbon metal gauges.
The argon in the C25 gas mix stabilizes the carbon dioxide and results in a nice balanced weld. The surface profile of the finished weld tends to be flatter and neater. With the correct weld settings, C25 produces little weld spatter. Cleaning up after welding mild steel or low carbon steel is minimal and easy.
