What is CO2 welding?

In CO2 arc welding, the welding wire wound in coil is fed into the welding torch by the feeding motor automatically. The welding wire that is electrified through the contact tip becomes the electrode to strike an arc between itself and the base metal. read more

CO2 welding is a welding process that uses carbon dioxide to protect the weld pool from oxidisation during the welding process. read more

Paintball co2 cylinders can even be adapted to use for welding. Hobart makes a kit with a fixed regulator/flowmeter designed for Hobart mig welders but it can be made to work on most any 115 volt mig that is made to use with shielding gas. read more

Carbon Dioxide (CO2) is the most common of the reactive gases used in MIG welding and the only one that can be used in its pure form without the addition of an inert gas. CO2 is also the least expensive of the common shielding gases, making an attractive choice when material costs are the main priority. read more
