What can you weld with 75 argon 25 CO2?

Hello Shawn, the 75/25 will work for welding with ER70S series solid wires on mild steel. It will also work with many of the flux-cored gas-shielded wires. Many of the flux-cored stainless steel wires will also work with the 75/25 shielding gas.

What is C 25 welding gas?

Praxair’s argon/carbon dioxide blends containing 20-25% CO2 by volume (StarGold™ C-20 and C-25), are commonly used for shielding solid wire used in a short-circuiting and globular transfer mode. A variety of material types and thicknesses can be joined using this gas blend in all welding positions.

How much does a bottle of argon cost?

Argon gas cylinders are considered the most expensive, with prices going up to $350 for a new cylinder.

Can you weld with just CO2?

The most common of the reactive gases used in MIG welding is Carbon Dioxide (CO2). It is the only one that can be used in its pure form without the addition of an inert gas. Pure CO2 provides very deep weld penetration, which is useful for welding thick material.

What should my MIG welder gas be set at?

The polarity connections are usually found on the inside of the machine. Set gas flow. Turn on the shielding gas and set the flow rate to 20 to 25 cubic feet per hour.

How tall is a 125 CF argon tank?

42.7 in.

Can you TIG weld steel with 100 Argon?

Argon does stay inert, even at elevated temperatures. It also produces easy starts, maintains a stable arc, and helps to keep the tungsten electrode clean. So, for TIG welding of steel with Argon can work, whereas MIG welding of steel benefits by using an Argon/CO2 blend.
