Why is there no gas flow when I depress the MIG torch trigger switch on my Infinium WELD STAR WS-MU4-1?

The absence of gas flow could stem from several reasons. First, the gas cylinder might be empty, requiring a replacement. Second, the gas regulator could be turned off, so ensure it is on. Third, the gas hose could be blocked or cut, necessitating a check, repair, or replacement. Lastly, the torch trigger switch lead may be disconnected or faulty, requiring reconnection or replacement.
