Portable Arc Welders
Portable over shoulder Inverter arc welders use a coated metal electrode to provide an electrode, filler material and shielding gas by means of a burning flux coating. These rudimentary machines are a constant current power supply and are the most widely used welding machine inverters in the world. The very nature of portability is derived from the over shoulder ease of transportation of these welders. Please note that welding with an inverter strung over the shoulder is not reccomended and shoulder mounting is for transportation only.
