Hi all,

I just picked up my first TIG in the 255EXT for doing hobby machinist, bike parts, car parts and whatever else throws itself up.

I had a quick query with regards to the gas use (it seems to be using it very rapidly).

Is it normal to be able to hear the gas rushing from the machine when its turned off?
Same as above but with the machine turned on but not welding (It's a bit hard for me to differentiate between the gas noise and the fan noise)?

Thanks,
Angus
