i`m using a mma inverter for tig weldin and i want to upgrade it.... i want to put a gas valve inside.... i`ve tired to start/stop the argon flow from the bottle



where can i find a proper electro-valve.... i gues to order a spare part from an inverter it`s to expensive

Get a gas valve off ebay. Usually in the industrial controls section. I picked up 10 for $40

Make sure it is the right voltage, has the right size fittinge and is normally closed.

hope the presure in no more than 150psi from the flow regulator

 

[madkayaker]

there is little pressure after the regulator

The pressure after the regulator is 20-50PSI with the valve closed.
