III. Activating the 'Safe Welding Off' (SWO) function (Hard)
A switch (DIP 1), located on the SAM-1A board (see electronic board on page 11), is fitted to the equipment to
provide a robust safety feature. Simply switch both switches to ON.
IV. SWO (Safe Welding Off) wiring and feedback
If switch 1 (DIP 1) is set to the ON position and switch 2 (DIP 1) to the OFF position, the safety device must be wired.
A dedicated terminal block (X5) is available on the SAM-1A circuit board (see circuit board on page 11).
