If anybody is in before Sunday could you reply with the MIG/TIG gas bottle pressures?

Just want to do a little MIG welding and possibly TIG if I have time but don't want to waste a trip if the gas is out.

Cheers

Had breaker trip out issues with both the MIG and TIG yesterday afternoon. 

Later the TIG started to behave itself, not sure about the MIG, didn't have time to retest that.

Will try and pop up next Sunday afternoon and have another look, if anybody else has time to give it another try before then please report back..

Thx

Not sure about the TIG 

The Mig was not tripping at Hackney road as such but did behave inconsistently 
 - often after welding for a bit the weld profile would change and you would battle to maintain a bead at all 
 - if you set up did a weld and the came back you would then need to retune the settings

The mig was exhibiting those traits on Sunday, perhaps it will sort itself out again with a bit of fiddling. I have often found that it takes a minute or so of welding before it starts to give a stable arc and thought that it would be like that on Sunday. But then it trpped the circuit breaker a couple of times so I have up and tried the tig. That tripped the breakers twice in a row, but later was working fine.
