20120006792 | BATTERY POWERED WELDING SYSTEM - A battery powered welding system is provided. In one welding system a battery powered welder includes control circuitry configured to control a welding power output converted from power from an external battery power source. The battery powered welder also includes a wire drive assembly coupled to the control circuitry and configured to feed a welding wire using power from the external battery power source. The battery powered welder includes a case integrally supporting and enclosing the control circuitry and the wire drive assembly. The case is not configured to enclose the external battery power source. | 01-12-2012 |
20120152923 | SPOOL GUN ADAPTER - The present disclosure provides a welding system having a welder, a welding gun, and a welding gun adapter, the welding gun being a spool gun with an attached motor. The welding gun adapter receives welding power from the welder, and converts it to output power suitable for driving the motor of the welding gun. The welding gun adapter also uses received welding power from the welder for control power. The present techniques allow for the use of welding guns requiring motor power to be used with any ordinary welder. | 06-21-2012 |
20120241431 | WELDING ARC POWERED SPOOL GUN - The present disclosure provides a welding system having a welder and a 12V spool gun, in which the 12V spool gun includes a 12V motor. The 12V spool gun receives a voltage that is derived from a welding arc voltage, and drives the 12V motor of the 12V spool gun with the derived voltage. The present techniques allow for the use of a spool gun requiring motor power to be used with any ordinary welder. | 09-27-2012 |
