You can run the bigger welders from a 13 amp plug, you might blow an
occasional fuse if welding on the maximum current but i can't remember
the last time mine went.
Remember a 13amp fuse won't actually blow instantly at 13 amps, it will
take many seconds, they need 2 or 3 times there rated current to blow
straight away.
I can hear a hiss of gas from mine in use (not over the sound of the
weld but while the trigger is pressed).
A louder initial noise and then a quieter hiss.
Is your flow meter just a pressure gauge calibrated in l/Min ?, if so
invest in one with the ball in the vertical tube, they are much more
accurate.
Not that i can remember what mine is set to, more like 5 l/min i think.
if you are welding outside with any wind you need to turn it up more.
The times you quote would be for a continuous weld but in practice most
welds will only be a few seconds long if that.
So it lasts a lot longer than you think.

Hi, got the Clarke Mig 135TE welder in the end due to the power requirements
and this being the largest on a normal 13 Amp plug. Been giving it a try and
now seem to be settling to it. I found I had to turn the power and speed down
more than expected from the manual and had to play around a lot with the gas to
get it flowing. Most practice welds were gasless due to that issue!
So just a question on gas for those who have the experience. How much of a
sound should I get from the gas flowing. I now get a 'fhut' sound when
pressing the trigger if pressurised. But cannot hear a hiss as such. Is the
2-3 litres/min quoted in the manual such low flow for the handle? (it's not a
lot really I suppose)
Also I have seen some posts on the web about the small bottles lasting for only
short periods like, 6 minutes of welding. That would be 18 litres at 3
litres/min. So does the rate have to be really high despite the manufacturers
figures or are they set up wrong. You can get a small bottle of 110 litres and
at 3 litres/min that should last 36 mins by my maths. A bit different. I
appreciate there are bigger bottles out there but they do need storage and it
does depend on use.
Any thoughts?
Derek
