This safety rest is ESD safe.
Basic unit electric (for WFE P) safety rest with Stop Go function with fibre optic sensor for FE 75 and FE 80
The Weller safety rests with Stop Go function are recommended accessories for FE irons using the WFE or WFE P extraction units. A fibre optic sensor switches the extraction unit on when the FE iron is removed from the safety rest and when the FE iron is replaced in the safety rest, after a short delay to gather the fumes from any solder on the tip it switches the unit off. This reduces running costs.
