When it gets too hot to hold in your hand with a heiliarc glove just lay it down and let it cool off. I do use gloves, one reason is the heat, and the other is skin cancer. No tee shirt either. You couldn't use a water cooled rig in the field because of the problem with moving all over the place, up down and all around. Some of the new rigs are as small as a lunch box. Most are only as big as a suitcase and weight 40 to 60 pounds. All are air cooled.
Welding AC aluminum is a whole different animal than DC current on stainless...aluminum needs alot more amps............enough that it'll melt a TIG torch in a heartbeat.

Water coolers are not built into machines,they are add-ons for the TIG torch to keep it cool
