Abstract
A gas mixing apparatus for a laser cutter and a laser cutter including that apparatus. The mixing apparatus includes a housing defining a chamber, first and second inlet ports opening into the chamber at an obtuse angle to each other, and an outlet port. A hollow lance mounted in the first inlet port conducts a first gas into the chamber. In some embodiments, a gas sensor is in fluid communication with the chamber; and an adjustable pressure regulator is responsive to the gas sensor and is in fluid communication with the first inlet port to control the first gas as it mixes with a second gas flowing into the chamber through the second inlet port to maintain a predetermined ratio of the first gas to the second gas and thereby provide an assist gas. In some applications, a laser cutting head is in fluid communication with the output port to receive the assist gas.
