Flowmeters and Restrictors

Detailed below is Tesuco's range of flow control options for MIG, TIG and GMA welding, including flowmeters, flow restriction valves and flow rate testing units.

Flowmeters

Gallery

Flowmeters are used for precise flow control of the shielding gas to the MIG gun nozzle in welding applications. Tesuco has two in the range. One is 0-25 L/min for TIG and smaller flow MIG applications and the other is a 0-40 L/min for the larger flow MIG applications.

Flow Restrictors

Gallery

In some applications for shielding gas where the work is repetitious and the shielding gas flow does not need to change, flow restrictors can be the best option. These are units that attach to the outlet of the set pressure regulator and have a pre-set flow rate. They have a quarter turn on / off knob and have no flow adjustment. Tesuco can supply these in three different flow settings.

Flow Tester

Gallery

In all MIG and TIG welding applications it is important to establish the exact flow rate of the shielding gas for the welding operation being performed. This is best done at the welding gun nozzle itself. The Tesuco flow tester is a small economical unit that can be fitted at the end of the nozzle in a vertical position, with the wire feeder off the trigger on the gas can be activated and the actual gas flow observed.
