Abstract

A remote output control for controlling the output level of an electric welder power supply at a remote location and providing a source of isolated electrical power at the remote location is disclosed. The remote output control includes a water-proof, sealed housing fitted with an electrical receptacle and a potentiometer. A cable construction is electrically connected to the electrical receptacle and the potentiometer at one end and is provided with electrical plugs at the opposite end. A molded over wire y-adaptor is also included in the cable construction.

Claims

1. A remote output control for an electric welder power supply, comprising:

a housing having a bottom wall, a top wall, and a sidewall extending continuously around and extending between said bottom wall and said top wall, said bottom wall, said top wall and said sidewall together defining an internal compartment;

an electrical power receptacle disposed within said internal compartment and extending through said sidewall;

a rotary potentiometer disposed within said internal compartment and having a control shaft extending through said top wall;

a control knob secured to said control shaft for turning said control shaft;

a first length of insulated cable comprising a plurality of separately insulated wires;

said electrical power receptacle electrically connected to a first group of wires of said plurality of separately insulated wires;

said rotary potentiometer electrically connected to a second group of wires of said plurality of separately insulated wires;

a second length of insulated cable comprising said first group of wires

a third length of insulated cable comprising a said second group of wires;

a molded y-connector conjoining said first length of insulated cable, said second length of insulated cable, and said third length of insulated cable;

a first electrical plug joined to an end of said second length of cable and electrically connected to said first group of wires, said first electrical plug configured for reception by an electrical receptacle; and

a second electrical plug joined to an end of said third length of cable and electrically connected to said first group of wires, said second electrical plug configured for reception by a remote control receptacle of the electric welder power supply.

2. The remote output control of claim 1, wherein said rotary potentiometer is a multi-turn rotary potentiometer.

3. A remote output control for an electric welder power supply, comprising:

a housing having a bottom wall, a top wall, and a sidewall extending continuously around and extending between said bottom wall and said top wall, said bottom wall, said top wall and said sidewall together defining an internal compartment;

an electrical power receptacle disposed within said internal compartment and extending through said sidewall;

a rotary potentiometer disposed within said internal compartment and having a control shaft extending through said top wall;

a control knob secured to said control shaft for turning said control shaft;

an electrical connection receptacle disposed within said internal compartment and extending through said sidewall;

said electrical power receptacle electrically connected to said electrical connection receptacle,

said rotary potentiometer electrically connected to said electrical connection receptacle;

a first length of insulated cable comprising a plurality of separately insulated wires, said plurality of separately insulated wires comprising a first group of wires and a second group of wires;

an first electrical plug joined to an end of said first length of insulated cable and electrically connected to said first group of wires and said second group of wires, said first electrical plug configured for reception by said electrical connection receptacle;

a second length of insulated cable comprising said first group of wires

a third length of insulated cable comprising a said second group of wires;

a molded y-connector conjoining said first length of insulated cable, said second length of insulated cable, and said third length of insulated cable;

a second electrical plug joined to an end of said second length of cable and electrically connected to said first group of wires, said second electrical plug configured for reception by an electrical power receptacle; and

a third electrical plug joined to an end of said third length of cable and electrically connected to said first group of wires, said third electrical plug configured for reception by a remote control receptacle of the electric welder power supply.

4. The remote output control of claim 3, wherein said rotary potentiometer is a multi-turn rotary potentiometer.

5. The remote output control of claim 3, wherein said electrical connection receptacle is of the twist lock type, and wherein said first electrical plug is of the twist lock type.

6. The remote output control of claim 3, wherein said y-connector is molded over said first length of insulated cable, said second length of insulated cable, and said third length of insulated cable.
