About the K-15R Portable Rod Oven – 15 lbs. Capacity
The K-15R is designed to store 15 lbs. of welding electrodes during transfer from large shop ovens and at the job location. Economical, lightweight and easy to carry, our K-15R model maintain rods at ideal temperatures to prevent moisture pick-up and to optimize welds.
The K-15R small capacity is suitable for the hobby welder as well as the highly trained professional. It out-performs most portable ovens on the market and has a solid steel construction for long product life and durability. It’s low cost and compact size enables shops to keep 10 or 20 on hand for welders heading out to the field.
The K-15R features an external 120V-12 Amp Receptacle for extending power supply to a connected power tool or another Keen rod oven.
The K-15R has a solid steel construction for long product life and durability. The exterior is powder-coated in KEEN blue and features a rugged handle for carrying the unit. 1″ (2.54 cm) Thermal insulating wool makes oven energy-efficient and keeps electrodes hot and moisture-free.
The K-15R design features a round inner chamber with a square exterior to provide stability while standing in an upright position. The unit features a liftable “rod elevator” with handle that supports the rods. When the elevator is lifted, the rods splay outwards for easy removal from the oven. The elevator then is dropped back into the oven in one movement. A red “ON” indicating light is standard on the oven so a user or welding inspector can see the unit is powered on from a distance.
The custom-designed heating elements used on our portable ovens are part of a new class of highly energy-efficient, technologically-advanced heating elements that have a very low environmental impact. Unlike elements that utilize common resistance wire, our elements are self-limiting semiconductors that have a dynamic power output, so there is no steady state current or steady state power. They reach maximum operating temperature in just 5-10 seconds and not long after a state of equilibrium is attained. At this point, the resistance increases and the current flow drops to almost zero. The resistance will decrease on its own if ambient temperature decreases to allow more current to flow to the element to maintain maximum heating temperature with the lowest energy output. This results in a very low amperage draw enabling the oven to be extremely energy-efficient in the field.
Quality Temperature Control and Electrical Safety
Because of our unique self-regulating heating technology, thermostats are not a necessary safety feature for our portable ovens. The only case in which they would be necessary is if the user wants to reduce the temperature below 250°F for storing electrodes that require lower temperatures than low-hy rods.
