Thanks Ken, I am not sure why, but on the web there have been notes of the same behaviour, it seemed to be impossible and then difficult to get gas to flow. Now its fine and controllable. Why? - I am not sure, maybe just a new valve with some plastic dust in the system? Tried different bottles as well and I now get the hiss and it is easier to weld!
Yep, got 2mm practice sheet and the first job is on 3 mm. (when I manufacture the bracket) More practice ahead! Found this offer for disposable small bottles - Large capacity £15 each buy three get the third half price. CO2, Argon/CO2 And Argon all the same price and you can mix them. http://www.thewelderswarehouse.com/Welding/Mig_Tig_Gases1.html And this for Refillable 1300litre Argon/CO2, no rental. http://www.r-techwelding.co.uk/welding_equipment/welding-gas Are these prices good in your experience?
