Cooling system for arc welding
First Claim
1. An electric arc welder with an internal compartment containing heat generating electrical components, said compartment having an end wall defining an outlet wall of a plenum chamber and having large, unimpeded outlet openings with a combined first area, said chamber having an inlet wall with an air opening having a second area;
- said inlet wall and outlet wall being generally parallel to define a given volume for said plenum chamber; and
, an air moving device with an axial inlet ring and a radial discharge impeller mounted on said inlet wall over said air opening to pressurize air in said plenum chamber to force air from said outlet opening at a velocity exceeding about 2000 ft/min.
