WELDING GAS FLOWS PLEASE ??

[Richy B]

Hi all, i use a snapon turbo130 mig welder 240v for general at home weldy stuff, I have just converted from the disposable bottles for a 20 kilo argon mix, i purchased new regulators and a flow meter ( ball in a glass tube type)

Question is what should i be running it at ?? i read somewhere 20 litres/minute, But if set at that it sounds more like a air line than a gas bottle, Any tips please ?? Thanks in advance

I set our TIG and MIG at the bare minimum to get a good weld and not a cfm more! No idea if this is right but certainly seems logical

I use about 12

Yes,I was told 11 litres/minute for general use on my welding course.

About 10 in still air, but upwards if it's breezy.

i'm sure the little chart boc gave us said 8 - 12, i set mine at 10 and seems to work ok

C&G MIG course said 10-15 depending on breeze/draught

Turn it down until it welds poorly, then turn it back up a bit

Turn it down until it welds poorly, then turn it back up a bit

Although not quite technically right, it is sound advice as too much gas can cause the weld to cool which gives much less penetration.

In the workshop I run 10L ………..outside it depends on the wind, anything from 10L – 15L ………….if I need more than 15L then its time to erect a wind break or call it a day !
