This 120 volt system (220 volts available) is ideal for applying hot melt adhesives onto flat surfaces. The unit shows the optional pressure bar attachment for materials up to 1/2`` (1.3 cm) thick. Without the attachment the operator moves the item to be glued over the glue roller.  It`s glue tank holds about five pounds of hot melt. An electronically controlled thermostat provides variable temperature control.  The speed of the roller is also variable.  There is a motor lock-out switch to prevent damage to the motor if it is turned on before the adhesive is molten.
