Consequently, claims for material damaged in shipment must be made by the purchaser against the transportation company at'the time the shipment is received. POWER SOURCE The ML-2 was designed specifically to be powered by the SAE-600 motor-generator or engine driven power source. Other variable voltage welders, such as the SA-750 and Idealarc, can also be used as ML-2 power sources. The SA-750 does not have the dual continuous control feature of the SAE welders. Therefore, to permit easy adjustment of current and voltage, the ML-2 should be equipped with the optional meter kit when it is powered by an SA-750. Idealarc transformer rectifier welders with a 450 amp or larger DC output can also be used as an ML-2 power source. However, an ML-2 Power Pack Kit must be installed on the Idealarc to provide the necessary voltage for the field of the wire feed motor. When using a power source with a rating less than 500 amperes continuous duty, be careful not to exceed the power source duty cycle. CONTROL AND ELECTRODE CABLE ASSEMBLY- ML-2 TO POWER SOURCE This cable assembly consists of a 2/0 electrode cable and a five conductor control cable. The control cable has a polarized plug at the ML-2 end and is lugged at the power source end. The control cable and electrode cable are properly connected to the ML-2 when shipped. You must obtain another 2/0 cable of suitable length for a ground cable. The ground cable is not supplied as part of the ML-2 package. The control cable, electrode cable and the ground cable are connected as follows: A. Control Cable SAE-600 - Instructions for connecting the five conductor control cable to an SAE power source are given on diagram M-7232 located on page 18 in this manual and on the inside of the ML-2 wire reel case door. SA-750 - See diagram M-8747 on page 19 of this manual for instructions for connecting the control cable to the SA-750. When an ML-2 is installed for automatic operation with an SA-750 power source, a wiring change in the ML-2 control box is necessary if the off-inch switch is to be used to stop the arc at the end of the weld. To do this, open the ML-2 control box door. At the terminal strip, remove the lead #24 coming from the current relay. Tape the end of this lead. Do not remove the lead #24 going to the control cable connector. If the arc is to be stopped by raising the gun away from the weld, this rewiring is unnecessary. Idealarc - Complete instructions for connecting an ML-2 to an Idealarc are given in the ML-2 Power Pack Kit instruction. B. Electrode Cable Connect the electrode cable to the 'Electrode' stud on the power source. With an SA-750, use the 'Minimum - 525' current range stud. C. Ground Cable Connect one end of the ground cable to the 'To Work1 stud on the power source. Connect the other end of the ground cable to the work. CONDUCTOR CABLE- ML-2 TO GUN The conductor cable carries the welding current and electrode from the ML-2 to the gun. Insert the male end of the conductor cable into the socket in the control case. Screw the sleeve tightly into the coupling. GUN When shipped, the gun is readytofeed 5/64"elec-trode. If you must use 3/32" electrode for a particular application, replace the nozzle tip with Tip S-8087-6. These tips must be ordered separately. CONTROL CABLE EXTENSION (Optional) The five conductor control cable extension is made in 50 foot lengths and has screw connectors at each end. It is connected between the standard 25 foot control cable and the control case. Use a maximum of four 50 foot extensions. The extra 2/0 electrode cable needed to carry the welding current is not included with the control cable extension. The ML-2 can be used with later power sources than those listed above. Contact the factory for installation instructions. - 2 - WIRE REEL CASE CONTROL CASE CONTROL CASE CABLE ASSEMBLY ELECTRODE CONDUCTOR CABLE CONTROL CASE WIRE SHEATH EXTENSION • •S- WIRE SHEATH EXTENSION (Optional) When the ML-2 is shipped, the control case and wire reel case are bolted together. In some applications, it is more convenient to separate the two cases. When this is done, the wire sheath extension is necessary to carry the electrode from the wire reel case to the control case. This wire sheath extension is made in 15 foot lengths and has screw connectors at each end. Use a maximum of two 15 foot extensions. METER KIT (Standard after ...
