hi all, i have lurked around here gleening titbits for a while, but now i have a specific question.

i am welding body panels on a dub bus and gone from no gas to gas and using 0.6 wire in a clarke 151en with argosheild light,

what i need to know is what pressure or flow rate should i be looking at for the gas,

any help would be greatly appreciated.

You set it by flow rate.

Start at about 8-10Lpm & see how you get on.

When welding inside I use less & outside more. Sometimes lots more if its windy & I cant get the area shielded well enough.

thanks mate, i have started using an old O2 twin gauge reg setup to keep cost down, but output guage only does pressure and to big increments to do that low a feed, do you know who might sell a 1/4npt bottom entry cfm/lpm guage.

doh... just seen this http://www.weldequip.com/flowmeter.htm i wonder if this is a control valve as well as a flowmeter, could just put that on my outlet turn on the cyl and connect my pipe to the outlet of this...............

Yes, it is.
