What Regulator/Gauge setup for Synchrowave 250 TIG?

Looks like the one you ordered from HTP comes with a barbed hose fitting, possibly similar to the one I believe is on the outlet side of your current flow meter. The only issue would be if the hose size you have is different than what the hose barb is set up for. I'd bet I could make what you have work, even if I had to simply cut off your existing hose and connect it to the new hose barb with an adapter and a short length of the correct size hose. Most home supply stores have a selection of hose barbs and adapters in the plumbing section or in hardware with the air tools.


I missed that HTP searching last night. That looks like a good inexpensive choice. I'd probably go that route myself if I needed a 2nd flow meter, and I may just say that link for when I need one for my Maxstar vs stealing the one off my Syncrowave when needed.

pretty much always used a Ball type reg. BUT.......in a pinch you could use just about any reg. as long as it could handle the high pressure side?

Maybe. You'd need to find a Y that would fit the inlet on both flow meters though. Most dual flow meters I've seen come off a 2nd LP port on the reg portion rather than the same LP port. That would also assume both will run at the same intermediate pressure.

You could.If I've got it right... You'd set your new meter at the tank to about 25cfm then set the original meter to your welding cfm (15ish). The difference would be available for purging.
But honestly, back purging wouldn't be high on my list just starting out. Most times I need to purge something I just turn up the post flow, tap the contactor and flow some gas where it needs to be.

Yes, you should be able to use your MIG welder reg. And when you do get that new reg/flow meter, you only need that, not that and the old meter that is on there. Save that old meter in case you have to do a back-purge setup for stainless steel TIG or something like that in the future.

Edit: rereading this thread... don't confuse the poor guy about needing dual flow meters/regs or anything. Just because someone fastened that thing on there doesn't mean it was original equipment. Ditch the old flow meter and use the reg/flow meter in it's place on the tank.
