Henkel KEEN KF-100A - Manual (Page 4)

• When using the unit at a distance where an extension cord becomes necessary, a 3-conductor
grounding cord of adequate size must be used for safety, and to prevent loss of power and
overheating. Use only a UL listed extension cord suitable for outdoor use. Make certain wire size is
large enough for A/C amperage rating of unit.
Operation
Load oven with flux. To turn unit on, simply plug the power cord into the appropriate single
phase A/C power source. (See oven nameplate for voltage rating.) Indicating light glows when power is
being supplied to the heating elements. Plugs are not supplied on 240-volt models due to the many
different receptical configurations in the field. All units meet electrical code requirements when used
with a grounded power source.
***CAUTION: DO NOT USE ON D/C POWER SUPPLY! ***
The KF-100A is designed to vent around the perimeter of the lid. In instances
where there is high moisture content in the flux, the interior of the lid is designed
to channel condensation into the well built into the top lip of the oven.
Temperature Setting
The thermostat on the model KF-100A is factory preset at approximately 275ºF but has a range of
100º - 400ºF. To adjust temperature setting, disconnect oven from power source, then remove snap-in
plug from element cover. This exposes thermostat adjustment screw. Using a small screwdriver, adjust
set screw until desired temperature is attained. (Turning set screw counter clockwise increases
temperature, turning set screw clockwise decreases temperature.) One-quarter turn equals approximately
35ºF. Replace snap-in plug and reconnect oven to power source.
Guide to Storage
See the enclosed guide to storage. This guide may be used in the absence of storage information
from the flux manufacturer. In critical situations, contact your flux manufacturer.
Functional Description
The model KF-100A is a portable hopper style flux oven designed to hold 125 pounds of welding
flux at moderate optimum temperature. Temperature is regulated by a field adjustable thermostat with an
indicating pilot light, and monitored with a bimetal thermometer. This oven may be used as a portable
unit or may be readily attached from its carrier and mounted directly to the welding manipulator. The
model KF-100A is insulated with a full 2” of thermal insulating wool and is equipped with lifting lugs.
