Remotely controlled welding machine
First Claim
1. A welding retrofit kit comprising:
- a transmitter module configured to be disposed within a first welding device, wherein the transmitter module is configured to transmit a signal indicative of a desired welding operation based on a selected power source mode, wherein the signal is transmitted at a first voltage level for a first power source mode and at a second voltage level for a second power source mode;
a receiver module configured to be disposed within a second welding device, wherein the receiver module is configured to receive the signal indicative of the desired welding operation; and
a comparator circuit configured to determine the selected power source mode based on the voltage level.

Abstract
The present invention is directed to a remotely controlled welding machine. A remote control uses the welding circuit to transfer information to a welding power source. The information to be communicated to the power source includes welding power source output command information (amperage/voltage control), welding circuit on/off information (power source output contactor control), and power source mode control (constant voltage/constant current). A transmitter transmits the desired welding operational parameters to a receiver disposed in the power source. The transmitter is constructed to use only a small amount of power which, preferably, is supplied by one or two low voltage replaceable and/or rechargeable batteries. Additionally, an open circuit voltage is not created between the power source and an electrode holder when an arc is not present.
