ARCON Welding in Salisbury, Maryland manufacturers the Workhorse line of welding power sources that have Proven Reliability, Rugged Construction and Great Welding Chacteristics. Energy-saving Inverter circuitry is based on the time-proven SCR Inverter design. Machines are designed to be simple to operate, deliver superior welding performance and to endure harsh work environments. All Workhorse welders now include the Seahorse Anti-Corrosion Protection Package that guarantees against corrosion-caused failures for 5-years. Welders are thermally protected in 5-zones to guard against internal damage from overheating and housed in a fiberglass reinforced case with dual fold-away handles and extra thick skids underneath to guard against external damage. Current/Time controlled cooling reduces the amount of dust being pulled into the machines. Current Workhorse models by ARCON include the Stickweld 300S with Lift-Start TIG ignition, the TIGweld 300ST with Arc Starter TIG ignition, the Robotic 300ST-R, and the MIGweld 300MS.
