Abstract
In a hot melt adhesive dispensing gun, an electronic circuit is constructed to enable the operator to set a desired temperature to which the glue is heated. This set point is automatically raised a predetermined amount when the glue is flowing in order to compensate for the drop in temperature caused by the loss of heat to the glue and atmosphere.
