Keen KHT-900 Welding Electrode Rebake Oven
About the KHT-900 Electrode Rebake Oven – 200 lbs. Capacity
The Keen KHT-900 is an electrical, high-temperature industrial oven that is designed for rebaking flux-coated, shielded metal arc welding (SMAW) electrodes. It has a 1000 lb. storage capacity and a temperature range of Ambient-999°F (Ambient-537°C).
For welding electrodes that have been contaminated by moisture, the high temperature KHT-900 rebake oven is your answer. Highly efficient and easy to use, it is the perfect solution to restore up to 1000 lbs of moisture-contaminated shielded metal arc welding (SMAW) electrodes.

Shelving Design
Our angled welding rod storage shelving is purpose-built not to inhibit natural convection- a common occurrence with competing brands that utilize flat shelving for storage. The unique welded-in shelves allow the insertion of full 50 lb. tins of welding rods up to 18 inches which is a unique benefit for nuclear and aerospace welding codes that require immediate heated storage of opened tins before use.
Most electrode manufacturers discourage ‘stacking’ of electrodes too deeply while being heated to allow for better airflow over the consumable. With our shelving design, heat reaches the electrode coating more effectively to stave off atmospheric moisture. Please see diagram below of the airflow action with our shelving design:
Quality Insulation
Efficient heating design must be supported by quality insulation. The Keen KHT-900 features features thermal mineral wool insulation. It is highly thermally-efficient and is installed within the walls and door of the unit.
Customization
We have the unmatched ability to customize any of our standard ovens, and/or design one-of-a-kind ovens for unique storage requirements. Welding codes are constantly changing, and Keen is ready to meet the demands of today’s welders.
