Just got the replacement for one that had an air leak inside the box. This one is leaking air from the water drain under the bottom. Have to pull the valve to get it to stay out so the air doesn’t leak. It seems like it is supposed to be in and not out. Either way the out position is the only way it doesn’t leak. Also, I only got an arc for a second and then no luck. Have air out of the nozzle and sanded to a bare metal ground. Hearing a click when I squeeze the nozzle,but no spark. Took over 2 weeks to get this one replaced. Am I headed that way again?
