System and method for dispensing product to a washing machine. A chemical dispensing system includes a system controller, machine interface, and pump controller that communicate through serial data buses. The system controller provides a user interface, retrieves washing machine status information from the machine interface, and issues product dispensing commands to the pump controller. The pump controller monitors pump status and dispenses product in response to commands from the system controller. The pump controller: (1) determines pump activation periods based on calibration data stored in a pump controller memory; (2) tracks pump usage and adjusts the activation period to compensate for pump wear as the pump ages; (3) disables the pump if conditions exists that preclude operating the pump; (4) monitors product levels, and (5) reports pump status to the system controller. Integral channels are included in the pump housing to provide stress relief to a squeeze tube.

A welding apparatus having an easily replaceable fan and a method of replacing the fan is disclosed. An opening is formed through the front panel of a welding-type power source to correspond to the profile of a cooling fan. The opening allows the cooling fan to pass therethrough unobstructed. Once inside the housing of the welding-type power source, the fan is positioned to generally occlude the opening and is then mounted to an inner surface of the front panel by a fastener secured through the front panel and into the fan.

Welder with front mount fan

A mid-plane baffle or plate having a fan mounted thereto to dissipate heat within a welding machine is provided. By centrally positioning a baffle and mounting a circulating fan thereto, cooling efficiency is improved thereby enabling more direct cooling of the internal components of the welding machine. The baffle also reduces the critical volume of the welding machine and allows the fan to operate more efficiently and pull an increased amount of cooler ambient air through the machine which creates a greater cooling effect during the cooling cycle of the machine. The baffle placement also improves welding start performance by operating as a barrier between the high frequency/high voltage components and the PC board (control electronics) of the welding machine. The baffle also improves flexibility of component placement within the welding machine.

Apparatus for a welding machine having a cooling assembly mounted to a mid-plane baffle for improved cooling within the welding machine

A welding machine includes a housing having a base and a slidable rack assembly to support a gas cylinder. The rack assembly is slidably coupled to the base of the housing to move between open and closed positions. In a closed position, the rack assembly is concealed underneath the housing and in the open position the rack assembly is extended outwardly from the base to support the gas cylinder. A plurality of wheels is provided to support transportability of the welding machine.
