Lost gas flow to Tig

[jordan1]

Tried to use the machine today, gas ok to it none from it, Discounted the torch as there is nothing coming from the machine with the hose disconnected. Any thoughts guys.

Probably the gas solenoid valve packed up, if its working you can here / feel them click when the triggers pressed, its usually an easy fix to replace them, worst case is that the valve is ok but the machine is not sending a feed to it, which may indicate a board fault, a few minutes with a test meter will soon tell you.

solenoid valve?

open the machine up, find the valve that the gas hose goes into and check if there any coming out when it should be. If not then either the valve is dead or tthere is a bad connection

Solenoid valves can sometimes stick, a few sharp taps can free them.

Just checked this morning and found that there is no HF arc in the machine, all I have is the fan running.

Turned out to be the torch switch. Thanks all for your suggestions.
