Changed gas, something is wrong

[Tatey]

I thought it may have been that as its been a month or 2 since i last welded so i got the shroud very close to the work but no joy. The mig welding forum has suggested it is due to a lack of welding gas, and it is possible that the valve in the torch is partially blocked causing the gas shortage. I have another valve at home in newcastle which ill be trying out on sunday, so hopefully that will be the problem solved.
