This'll be my first post in at least 4 years, if not more on this site. For the past few years, I haven't been into welding and just got back into and it is surely great to be welding again! My old machine was a Syncrowave 200 and I was used to all the functions on that machine. My new machine is a Syncrowave 210 and I thought it was to be surely an upgrade and only 1 thing so far is preventing me from thinking that, which is being able to manually purge the gas system, either to be empty after the day's work or to be able to set the gas flow exactly where you want it set on the flowmeter/regulator.

My question is that does an inline purge system exist that can be connected in between the flowmeter/regulator and the welding machine? Or how about do you guys go about this situation or does it not even cause a worry at all?
