Dual flowmeter 

Get your weldmonger dual flowmeter here

There are 2 main reasons why you need a dual flowmeter:

1. to purge stainless steel pipe or sanitary tubing or other parts that require argon shielding on the back side
2. the less obvious but just as important reason is to be able to use 2 welding machines off one gas cylinder

Dual Flowmeters got me out of a jam

I was teaching a TIG class a few years ago at a remote location.

We had plenty of tig welding machines...one for every student, but we started running out of argon and it was on a Sunday.

But no worries...because we were able to use dual flow meters to run 2 machines off a single argon tank.

It got us thru the class until Monday morning when the local welding supply opened.

A dual flow meter gives you options.

Options are a good thing.
