The Aftek Power Family of multiple operator welding units are designed to give the shipyard, power plant, paper mill, petrochemical, and general contractor industries the flexibility and portability of a multi-operator machine. Depending on the options selected - SMAW (stick electrode), GTAW (TIG), FCAW (flux cored), and GMAW (hard wire MIG) - applications may be performed by multiple stations. The basic configuration is set up for use with SMAW and arc gouging. With the use of a voltage sensing wire feeder, the weldor may perform MIG welding. If a voltage sensing wire feeder is not available, the Demand Pulse Mig option may be added to allow the use of a constant velocity wire feeder.
