Technical Field

[0002] The carbon dioxide welding machine is a consumable arc welding method that uses CO2 as the shielding gas. When working, a gas protection layer is formed around the arc to isolate external oxygen, so that the weld will not be oxidized and carbonized, thereby improving the quality of the weld and making the welding surface more beautiful and smooth. The carbon dioxide welding machine uses a manual CO2 shielded welding machine as the welding power source to achieve semi-automatic or fully automatic welding of the workpiece.

[0003] Carbon monoxide will be produced when using a carbon dioxide welder for welding. Because carbon monoxide is colorless, odorless, and imperceptible, it is not easy for workers to detect it.
