BLW-400SSW — PRE-SETUP

General Inspection Prior to Operation

The BLW-400SSW utilizes a welder/AC generator that has been thoroughly inspected and accepted prior to shipment from the factory. However, be sure to check for damaged parts or components, or loose nuts and bolts, which could have occurred in transit.

Ground

The nut and ground terminal on the welder/AC generator should always be used to connect to a suitable ground. The ground path should be of #8 size wire.

Connect the terminal of the ground wire between the lock washer and the nut and tighten the nut fully. Connect their end of the wire to a suitable ground.

Circuit Breakers

To protect the welder/AC generator from an overload, a 3-pole, 53 amp, main circuit breaker is provided. In addition 2-two pole, 25 amp breaker is provided for the G.F.C.I. receptacles. Make sure to switch both circuit breakers to the "OFF" position prior to starting the engine.

Extension Cable

When electric power is to be provided to various tools or loads at some distance from the welder/AC generator, extension cords are normally used. Cables should be sized to allow for distance in length and amperage so that the voltage drop between the welder/AC generator and point of use (load) is held to a minimum. Use the cable selection chart (Table 7 ) as a guide for selecting proper cable size.
