Keen K-MPO Multi-Purpose Holding Oven


Brief Product Description

The Keen K-MPO is an innovative solution for welding professionals that perform multiple welding processes under one roof. This unique welding oven has a variety of purpose-built shelving for storing different types of welding consumables. 50 lb. tins of low-hydrogen welding electrodes can be stored in the hexagonal shelving, the door rack for TIG 36” filler wire, reinforced cradled shelves for spooled welding wire, and a perforated flat shelf for plasma powders or other uses. Standard digitally-adjustable, ON/OFF microprocessor-based controller with ±1 degree accuracy, over-temperature control, welded door hinges, forklift pockets and much more. Maximum temperature 250F.


About the K-MPO Multi-Purpose Wire Oven – 6 / 12” (33 lb.) Spools, 8 / 10lb. tubes of 36” TIG Filler Rod, 600 lbs. Stick Electrodes

The K-MPO stores 6 / 12″ (33 lb.) FCAW wire spools, 8 / 10 lb. tubes 36″ TIG Filler Rod and 600 lbs. Stick Electrodes. Our floor ovens are the preferred choice for many large manufacturing, fabrication and aerospace facilities where centralized, tight control of welding electrode quality and cost is of utmost importance. Our K-MPO model maintains consumables at ideal temperatures to prevent moisture pick-up and to optimize welds.

Heavy-Duty Construction Features

  • Durable powder-coated steel exterior
  • Welded construction
  • Cradled perforated shelving allows for natural convection

  • 1 year limited manufacturer warranty

Performance Heating and Safety Features

  • 2″ (2.54 cm) thermal insulating wool for energy-efficiency.
  • Two long-lasting 1000W UL®-approved Incoloy-sheathed tubular heating element for effective heating.
  • Digitally-adjustable, ON/OFF microprocessor-based controller with ±1 degree accuracy
  • Stable, reliable temperature control
  • 4-digit LED temperature indicating display
  • Handy tactile increment/decrement keys on the controller’s water-resistant front panel enable easy temperature set point adjustment
  • Temperature readout in Fahrenheit or Celsius
  • Adjustable, thermocouple-actuated manual reset over temperature control(high limit fail safe device)

Shelving Design

The K-MPO features three shelving styles:

The perforated, cradled shelving in the K-MPO allows for natural convection within the oven and enables the spools to be supported on their sides without rolling out. The reinforced shelves are supported by a welded-in steel bar for stability and to prevent bending. Beneath the perforated shelves lies the tubular heating element, thus the spools are protected against contact with the heating element. With our shelving design, you can be assured that heat will reach your consumables safely and effectively and prevent atmospheric moisture contamination.

The K-MPO has secondary storage capacity in the door rack that is capable of storing 8 / 10 lb. tubes of 36″ TIG Filler Rod. The door is reinforced with welded hinges enabling to support the weight of TIG electrodes. The added TIG electrode storage capability makes the K-MPO more versatile than other products in the market.

Adding further to it’s versatility, the K-MPO incorporates the same perforated, angled shelving found on our stick electrode ovens. The rack is capable of storing 600 lbs of electrodes up to 18″ in length.


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.
