1.2 RECEIVING-HANDLING

Upon receipt, remove all packing material and carefully inspect for any damage that may have occurred during shipment. Any claims for loss or damage that may have occurred in transit must be filed by the purchaser with the carrier. A copy of the bill of lading and freight bill will be furnished by the carrier on request.

When requesting information concerning this equip- ment, it is essential that Item number, Serial number and Model number of the equipment be supplied.

1.3 DESCRIPTION

These power sources are designed for constant cur- rent Stick welding (SMAW), air carbon arc gouging (ACAG), and scratch start tig (GTAW). It can also be used for Mig spray arc (GMAW) and flux cored wire (FCAW) welding with an “off the arc”wire feeder. Table 1 -1 outlines the electrical and physical specifications of the available models.

1.3.1 POWER SOURCE

The power source is a constant current, Silicon Con- trolled Rectifier (SCR), three phase, star-connected transformer/rectifiertypedcunitwithsolidstatecontactor and control circuitry. It provides the volt-ampere char- acteristics desired for conventional Stick welding.

NOTE: The 453cc and 553cc may also operate from a 200 (208)- volt a.c. primary input using the 230 volt change over connections. However, when connected to this source (200-volt), the output is derated to 36 volts @ 400 amps (453cc) and to 38 volts @ 500 amps (553cc).

The 453cc and 553cc 50 Hz may operate from 380 vac or 415 vac primary input when using the 400 vac change over connection. When using this connection, the output voltage is derated from 38 v to 36 v (453cc) and 42 v to 38 v (553cc).
