These fusing ovens are like upside down top loaders — the box hinges up instead of the lid. This configuration allows easy access to the work on a table like surface. The interior insulation is high temperature fiber board. This board is a great heat reflector and facilitates rapid heating cycles. The elements are installed in quartz tubes on the ceiling. The quartz tubes prevent element scale falling on the work below. The boxes of these ovens are fabricated from aluminum and all the metal around the openings is heavy stainless steel. Levelers are standard; wheels are optional.
