Embodiment Construction

[0015] The present invention relates to a welding device, more particularly to a motor-driven welding power supply. Those of ordinary skill in the art will fully understand that the welding equipment described hereinafter includes not only welding devices and welding systems, but also systems such as induction heaters and plasma cutting systems.

[0016] see now figure 1 , the engine driven welding system 10 includes a housing 12 enclosing the internal components of the welding power supply. Optionally, the welding system 10 may also include a loading eyehook 14 and / or a fork recess 16 . Load eye hooks 14 and fork recesses 16 facilitate portability of welding apparatus 10 . Additionally, welding system 10 may also include handles and / or wheels as means to provide mobility of the equipment. Housing 12 also includes a plurality of access panels 18 and 20 . One of the access windows 18 provides egress from a top panel 22 of the housing 12 , while the other access window 20 pr...

Abstract

A welding-type system and method for providing supplemental output power in an engine-driven, welding-type system. The welding-type system includes a battery, an engine, and a generator coupled to the engine to be driven to generate a power. The system also includes a power conditioning circuit configured to convert the power generated by the generator to a primary welding-type power and an output configured to deliver the welding-type power to drive a welding-type process during a first state and a second state of the welding-type process. The system further includes a controller configured to monitor the welding-type process and selectively couple the battery to the output during the second state of the welding-type process to provide a supplemental welding-type power to drive the welding-type process during the second state of the welding-type process.

Description

technical field [0001] The present invention relates generally to welding systems, and more particularly to a system and method for providing auxiliary power for welding processes powered by a motor-driven welding system using batteries. Background technique [0002] Conventional welding equipment can be divided into two basic categories. Class one is known as static power welding systems, which receive operating power from a transmitting power socket. Category two is known as rotary power welding systems or engine driven welding systems, which are portable or autonomous stand-alone welding machines with an internal combustion engine. These engine driven welding machines operate using power generated by the engine and associated generator. [0003] While traditional static power driven welders are preferred in most settings, engine driven welders can perform welding processes when static power is not available and / or when greater portability is desired. However, these eng...
