This report conceptual idea, marks the realization of a welding package generated by the author in early 1993. The development of a prototype ultra-portable less than 50 lbs. welding power supplywire feeder combination within one enclosure has been successfully designed, prototype developed, welding laboratory tested, and utilizedevaluated in a shipyard production environment. The unit even in its prototype enclosure design sheet metal verses fiberglass or injection plastic molded weighs under 50 pounds and has a operating range of up to 300 amperes DC at 60 duty cycle while performing SMAW shielded metal arc welding, FCAW flux cored arc welding, and GMAW gas metal arc welding, spray and short circuit processes. The prototypes design offers the operator four process options along with mobility and simplicity of set up.
