Sorry I didn't realize that they didn't have watercooled torches in the southern hemispere

A water cooled torch is much smaller than an air cooled torch and lets you get in many places to weld that you can't do with an aircooled torch.

Most welders that are above the home garage size buzz boxes will have an argon gas solenoid and a second one for water flow to the torch that you can hook to a household ( or shop) waterline. They also make a self contained cooland pump/radiator that circulates a coolant mixture thru the torch and back thru a cooling coil to the tank---if using this system the second solenoid is unused----and can be attached to a second argon line to control the back purging gas---the tigdepot also sells a dual flow meter regulator that I use with doesn't then need a SECOND argon bottle/regulator
