SGW-250SS —WELDER OPERATING INSTRUCTIONS

Welding Cables and Polarities

Connect the welding cables (Figure 8) to the welder's output terminals located on the control panel. The output terminals have positive(+) and negative(-) polarities. Select the appropriate polarities according to the application (SeeWelding Application,Table 6).

NOTE

Attach terminal connectors at the end of each cable. NEVER connect exposed wires (Figure 9) directly to the terminal. Exposed wiring may cause shocks or di-electric breakdown from poor contact.
