Cooling System Back to top
Cooling system for i4:
The i4 is both water cooled and air cooled. The air cooling starts when the temp reach 42c and shuts off automatically at 37c. Welding can remain while air cooling is on.
The water cooling is loop based system that cools the transformer weld cables and spot gun. While the water cooling is running the welder can operate as normal.
The reason for the two cooling system is that Pro Spot found it being most efficient and will extend the duty cycle of the welder.
