PORTABM- ALTERNATING CURRENT WELDING AND CUTTING APPARATUS alternating current machines m*de by theabove company can accomplish difficult,heavy and fast work. The machines consist of a special coretype transformer for reducing the voltagefrom that of the power supply to thelower voltage of the arc. which in generalruns from IS to 55 volts. This machineis built to meet an A. Cof any voltage or frequency. The line consists of two welding machimcutting machines and a combination cut-ter and welder. For light work a rangeof from IS to 115 amperes is provided;for railroad welding a range of 50 to200 amperes is provided; for heavyfoundry work a combination of cuttingand welding machine with range of 100to 300 amperes is provided; for cuttingrivet heads and other medium work witha graphite arc, a 600 ampere machine ismade and for very heavy cutting athousand ampere machine is made.
