Thread: Mig - No Gas

Hi mate
I had many welders have that problem...when gas stops flowing weld turns to Aero bar,its called porosity no inert gas envelope to prevent oxidisation........The faults are either..... ****ed gauge.....or a little { ithink its called a solenoid] in the welder that could also be ****ed.......listen near wire feeder for the gas solenoid thing operating...........our sparky fixed it in a jiffy.........its a process of elimination...start with the Gauge.

Also check that its not a kinked/crushed gas hose prior to the welder.
I've sometimes had the issue with air tools where there's pressure at the tool, but as soon as you pull the trigger it stops. Twist in the hose or similar can allow pressure but now flow.

I'd also drop the hose off the regulator and make sure you've got good flow there for a start.

Hello,
This often happens when the bottle is empty gives a little pressure then has none to give, if new bottle then the what has been suggested is the way to go. To check the regulator undo the hose going to the welder and open the bottle if you have continuous supply of gas then look at the welding machine solenoid.
