I used one some time ago, it works as advertised, I've also used hard plastic chambers, each has a place.

Don't you have to keep a small but constant flow of argon going into it?

Yes

Yes

Richard,

Isn't it minimal, like 3-5cfh ?

I am a hobbyist/weekend welder trying to weld up some brackets for my friend.
Welding 1/4" 304L SS, using 3/32" 308L rod, 140 amp
Small bevels were ground on each side of the weld. A chill block was clamped on the back side. The plan was to weld both sides. Did some basic material prep by grinding the surface using a flap disk followed by an acetone wipe.

Problem: my puddle seems to swim around a lot, resulting in odd shaped, inconsistent beads. See photo.
Any advice is appreciated. Thanks.

is it 1/4" thickness?

i just checked the welding calc and it says your running way way to cold.
that would explain the big freeze lines.
calc says 220-300 amps.

Yes, depending on the size of the chamber and how well it's made. A box (think square or rectangle) chamber has areas that take more time to flush the air out then a round chamber
