21MX Gas Mixture Proportioning Device Series
Gas mixture proportioning device is a two-element gas mixing device which is designed for gas shielded welding. The device can proportion two kinds of gases which need to be used according to operation requirements in order to obtain well-proportioned gas mixture. With high proportioning precision and stable output pressure, the series of gas proportioning device is convenient to carry and use. It can be widely applied to various gas shielded welding sites in railway, shipping, chemical industry and machine manufacturing.
