...haven't been doing much with my welder recently (powerpro 256). when I turned on the argon there was an audible leak.

at first I thought it was the threads at the gauge so I reapplied the teflon tape. When I tried that it still leaked.

The whole body of the regulator is cracked. A hairline crack from the gauge to the discharge valve. Scary to think it could have blown off right in my face.

The unit is around a year and a half old and never seen much use. Never dropped or abused.
