Welding Tips and Tricks

Anyone using this large dia. cup setup from USAweld, just curious what flow rate works for you. This is for a WP-9 and WP-20 series torch

I run 25 on mine with about 3/4" stickout, of its too high you'll see the arc move, usually hear it as well. 17 torch but shouldn't matter...

There is no one quick answer for the flow for every need you might encouter with this. I fillet weld and outside corner will not get same coverage at same flow rate. I uses this lens with the pyrex and alumina cup. My flow rates can range from 12 to 25 depending on stick out and joint configuration. Short stick out or areas that contain the argon you can get away with 12 to 15. Outside corners 20 to 25. You just have to pay attention and increase flow rates if you notice a coverage issue.

Rick I presume you meant 25
The only reason I asked is I wasn't getting as good coverage as I expected. There may be another issue not caused by the gas lens, more time is needed to work thru this, thanks for the replys
