COMMANDER 400 INITIALIZATION SEQUENCE

AND ERROR CODE EXPLANATIONS

When the Commander 400 is started, the display flashes several messages during initializa- tion. They usually go by so fast you cannot see them. Each message correlates to an ini- tialization test that the microcontroller program runs. No message should be present for more than a few seconds before the next message appears. If any of these initialization messages remain on the display, there is a problem. The microcontroller’s program will not advance past that test.

The initialization period is over immediately after the “---” disappears from the display. Once past the initialization, under normal circumstances, the unit displays a welding current preset determined by the position of the front panel control knobs and switches. If a later control board (G2713-2 or -3 is in place, the message “cdr 400 rEAdy” scrolls across the display. Initialization is over after this message finishes scrolling. In the “Stick & Wire” model a preset voltage or actual voltage, as well as current, may be displayed after initialization.

If the microcontroller detects an error, the error code will show on the display first and then the unit may shut down. Use the “Error Code Explanations” on the following pages to aid in trou- bleshooting diagnosis.

If the unit begins to shut down first and then the error code appears, this is not a microcon- troller initiated shutdown. In this case the unit has shut down due to lack of fuel, engine fail- ure, etc.
