Connecting the Welding Cables

1.Make sure the generator/welder is OFF (not running).

2.Attach the correct size terminal connector to the free end of each cable. NEVER connect bare or exposed wires (Figure 23) directly to the terminals. Exposed wiring may cause electrical arcing or dilectric breakdown from poor connection.

3.When connecting the cables NEVER allow the cable or welder output terminals to touch each other.

4.The welder's output terminals are marked positive (+) and negative (-). Connect the welding cables to the output terminals as referenced in Table 5.
