Re: Getting rid of the initial surge/spike/waste of shielding gas. $20 mod. Eazy Pea
Just for grins i installed an orifice fitting on the back of my machine. i had to drill it out to #74 wire size to achieve 25cfh from my 50 psi HTP ball type flow meter. Flow should be consistent across a range of pressures because flow "sticks" as soon as it becomes supersonic through an orifice, regardless of pressure. The argon delivery does seem smoother, no rush at the startup. Will do some welding and see if there's any noticeable difference in welding performance.

The ball slowly rises to the flow rate. I did a little aluminum welding and the argon delivery is stable from start to finish, so that's a win. Although i didn't use your idea, Oscar, it got me thinking, and ultimately lead to a win.

I'm gonna try an in-line flow regulator and see how it does.

Something like that would be similar to what bakodiver did with the orifice. You'd have to place it very close to the machine as it's just a valve and would eventually let pressure build up in the hose between it and the machine, given enough time.

Yep, hose on bottom is a foot away from the welder.
