BLW-400SSW— WELDER OPERATING INSTRUCTIONS

Welding Cables and Polarities

Connect the welding cables (Figure 14) to the welder's output terminals located on the control panel. The output terminals have (+) and (-) polarities. Select the appropriate polarities according to the application (See Welding Applications, Table 13).

NOTE

ALWAYS attach terminal connectors at the end of each cable. NEVER connect exposed or frayed wires (Figure 15) directly to the terminals. Exposed wiring may cause shocks or di-electric breakdown from poor contact.
