doing a lot of aluminum, you will want to set up a water cooled torch.



This is very true. In fact I'd recommend that you get a water cooled torch
to
begin with if you possibly can. Use it for all your bench/shop welding and
only
use a gas cooled torch in the field. The cooling water can be supplied by
the
city or from a water cooling tank/pump unit. Water cooled torches are much
more comfortable to use for extended periods of time and are easier to use
in
confined places since they are smaller for a given amp capacity.

How much bulk and weight does water cooling add to the torch and hose ?

None.
It ends up about the same.
Air cooled torch cables have to be made larger to deal with the heat.
Water cooled torch cables can be smaller because of the water cooling.

The water-in line, and gas line are seperate, and the water-out line is
the power conductor.
So three smaller cables instead of one larger gas-power line.
