Abstract

A system and method for replaceable machine-mounted male input power connections includes a power connection unit that is at least partially arranged within a housing and configured to transfer power received from a power source to drive a welding process. The power connection unit includes an input configured to receive power from the power source, an output configured to deliver the power received at the input to drive the welding process, and a bus system, configured to connect the input and the output. The power connection unit also includes a male connector having a conductive post extending to a threaded cylindrical shaft. The male conductor forms at least a portion of the input or the output and extends from the housing through a coupling assembly. The coupling assembly includes a correspondingly threaded portion configured to engage the threaded cylindrical shaft of the male connector to the bus system.

First claim

We claim:

1. A method for mounting a male connector to a power bus of a wire feeder, the method comprising:
providing a bridging connector inserted through at least one sealed bulkhead and arranged at least partially within a housing of the wire feeder;
inserting a first cylindrical portion of the male connector into a first end of the bridging connector;
exposing a second cylindrical portion of the male connector extending from the first portion, wherein the second cylindrical portion is configured to engage a receiving connector;
connecting the power bus to a second end of the bridging connector, wherein the power bus is configured to transfer power within the wire feeder; and
the connection of the bridging connector to the power bus and the male connector providing an electrical channel conduit within the bridging connector for electrical current flow between the male connector and the power bus.

2. The method of claim 1 , further comprising fixably securing the first cylindrical portion of the male connector to the bridging connector with at least one set screw.

3. The method of claim 1 , further comprising threadably engaging a threaded cylindrical shaft of the first cylindrical portion of the male connector to corresponding threads on the first end of the bridging connector.

4. The method of claim 1 , further comprising sealing the at least one bulkhead with at least one o-ring.

5. The method of claim 1 , further comprising encasing at least a portion of the bridging connector and the at least one bulkhead within a housing.

6. The method of claim 4 , further comprising providing a second bulkhead in operative communication with the first bulkhead, wherein the first and second bulkheads compressively receive and secure a portion of the housing therebetween.

7. The method of claim 6 , further comprising sealing the bridging connector, the first bulkhead, and the second bulkhead with a first o-ring held between the bridging connector and the first bulkhead and a second o-ring held between the first bulkhead and the second bulkhead.

8. The method of claim 6 , further comprising sealing a portion of the housing with a gasket arranged between the second bulkhead and the housing.
