Circuitry and plumbing to provide control of the shielding gas flow basic information required to, and maintain control/feeder. This manual will restrict It self mainly to the wire control/feeder and its optional equipment.

To end adjust hub tension, slowly unwind wire and pull toward the drive roll gears to check hub tension, wire should unwind freely, but hub tension should be sufficient to keep it taut and prevent backlash when drive motor is stopped.

This eliminates much needless lost time and effort. The data collected here dicusses lems of gas metalarc welding processes.
SECTION 6 DATA CHARTS - GENERAL The two basic transfer Spray types of metal transfer are spray and short circuit. comprises a steady stream of fine droplets moving physical space from the electrode to the workpiece. The short welding technique transfers metal from the electrode to the workpiece on contact only. The electrode physically touches the work and, since it is electrically energized, short circuits the welding circuit. The short circuiting action occurs many times per second.
