right untill i get any good at this tig welding malarky im not going to even consider aluminininium, so i got a dc stick welder and my main ideas are to buy
http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWAX:IT one of them and
http://cgi.ebay.co.uk/Mig-Welding-Ga...item483a894693 one of them and one of these
http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWAX:IT

or would i be better getting one of these http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWAX:IT

if i do buy the solenoid then does anyone know of a pcb diagram that i could put a pot onto so the gas solenoid stays on for a variable ammount of time after the weld has stopped to cool the work?

also im thinking of putting a car starter solenoid inline with the power lead so its not on all the time is this something that is feasable or do i just need to be a bit careful when i put the torch down?

also eventually i would like to go hf start so any info on that would be greatly appreciated.

oh the stick welder is a giant mma 200amp
