WM BLITZ VIDEO #6 Does Argon Flow Rate Affect Cleaning Action?

My good friend Andrew Cardin came for a visit and we filmed a few videos.

This is one of them.

We set out to weld a simple outside corner joint on some 1/8" thick pieces of 5052  aluminum and while the welds looked ok, something was just not quite right.

So we stopped and did a quick down and dirty test on argon flow rates to see if we noticed a difference in cleaning action path.

The results were eye opening for me.  

A day later, Another friend came to visit and he brought his argon flow rate tester.

We learned the flowmeter was off quite a bit.

So while 20cfh of argon flow usually provides good results with a #7 gas lens cup, increasing to 30cfh made a huge difference in the puddle.

A test piece was used to determine the spot size of the cleaning action at different flow rates using a clear #7 furick cup.

 Once we set the argon flow rate to the optimum spot size for cleaning action, 

The bead flowed better and came out much shinier. 

Stay tuned for a future video on tuning argon flow rates.

PS. the clear cup I used in this video is the new Furick #7 and I have put together a nice Lucky #7 combo kit that includes one clear cup and one ceramic along with all mounting hardware like collet, gas lens, insulator, and o rings.

We are looking for a good and affordable pee shooter gas tester but until we can source that, arc zone offers them

Amazing that CFM makes that much difference! Thanks Jody!

Do you sell those “pee shooter” flow checkers Looks like something I could use . Sometimes the tank is facing away and I’m already about 8’ away from the gauges , so the “pee shooter” would be just the ticket
