How to reduce welding processes costs by lowering shielding gases costs?

The use of shielding gases to optimize the atmosphere in welding processes, whether MIG/MAG (GMAW) or TIG (GTAW), has numerous benefits and technical advantages.

There is no doubt about it.

However, when comparing the cost of mixing commercial gas for welding, for example C25 mixture (25% CO2 in balance with Argon), with the cost of pure Argon, we note that the technical advantages represent a greater expense and may be more expensive the cost of your welding product or service.

Naturally, the cost of pure gas or gas mixture depends on a number of factors, such as the monthly volume consumed, distance to the supplier and type of supply.

Therefore, for welding processes, the ideal scenario would be to have the productivity, protection, less amount of spatter, … finally, the benefits that a mixture of gases provides the weld and at the same time, being able to work with the cost of pure gas.

This is exactly the advantage that a gas mixer represents.

See the spreadsheet below, which compares the cost of consuming commercial gas mixtures (ready-made) and the cost of installing a gas mixer in your factory and producing your own mixtures.
