Shop Safety Device (“Memory Compensator”)

Have you ever returned to you workshop, layout room or garage after several hours or even over night to discover that you forgot to unplug your soldering iron or glue gun? This used to happen to me. I scolded myself for ‘what might have been’.

A simple solution is at hand with components available from a hardware store.

These components include:

· a countdown wall timer (counts down to ‘off’);

· an electrical device box (steel or PVC);

· a cord with a three-prong grounded plug;

· a strain relief connector for where the cord enters the box; and,

· a typical wall outlet with double cover plate to suit the shape of the timer and wall outlet.

Wiring is very basic – for those who need assistance, timers come with instructions for wiring to a light or a bathroom fan. You simply need to wire the outlet in the circuit where one of these would go. I chose a timer that counts down in increments of 30, 15, 10 and 5 minutes. Longer and shorter timers are available.

To use, simply plug the glue gun or soldering iron into the outlet on the device, plug the device into a grounded wall outlet and press the timer button for the desired time.

I store my soldering equipment, glue gun and ‘memory compensator’ in the same place. It has become a habit to use this device whenever and wherever I solder or hot glue. I usually remember to turn the timer off when I am finished but when I don’t it takes care of itself.
