Arc-Master · Electrode Ovens & Accessories
Arc-Master electrode ovens are welding rod drying and holding ovens in six models, from a 5 kg portable quiver rated to 150 °C up to a 200 kg floor-standing oven rated to 500 °C with digital temperature control, all built in powder-coated pre-galvanized steel with mica band heating elements and ceramic wool insulation.

Where it is used
Features
Low-hydrogen electrode coatings absorb atmospheric moisture, and that moisture becomes diffusible hydrogen in the weld metal. Hydrogen is the direct cause of cold cracking in hardenable steels, which typically appears hours after the weld is complete and after the inspector has left. A holding oven is the control for it, which is why welding procedures specify one.
The range covers a 5 kg portable quiver (10Si and 10Si-DTC), a 9 kg portable (20Si), a 50 kg shop oven (110Si) and 150 kg and 200 kg floor-standing holding ovens (250DT and 450DT). The full comparison is in the specification table on this page.
The 110Si, 250DT and 450DT use digital temperature controllers and thermometers; the 10Si, 10Si-DTC and 20Si use analogue control. Where a procedure requires a recorded holding temperature, the digital models are the ones to specify.
The 250DT and 450DT reach 500 °C, which is the range required for re-baking electrodes rather than merely holding them. The 110Si reaches 300 °C, and the portable quivers 150 °C — holding temperatures, not re-baking.
All models use mica band heating elements with ceramic wool insulation — 38 mm on the 10Si, 48 mm on the 20Si. The bodies are pre-galvanized steel sheet with powder coating, which is the right specification for a humid coastal environment.
The 10Si-DTC accepts 110 V or 220 V AC, so it works on site supplies and generators that the single-voltage models would not. Otherwise it matches the 10Si specification.
The portable models include an inner basket, basket hooks, a tilt stand, a light indicator and insulated shoes as standard, rather than as extras.

Frequently asked
Low-hydrogen electrode coatings absorb moisture from the air, and that moisture becomes diffusible hydrogen in the weld metal. Hydrogen causes cold cracking in hardenable steels, often appearing hours after welding is finished. Holding electrodes at temperature is the control for it, and most welding procedure specifications require it.
Follow the electrode manufacturer’s published figure and your welding procedure specification — holding and re-baking temperatures differ by consumable and are not interchangeable. What matters when choosing an oven is that it reaches the figure your procedure requires: the portable quivers reach 150 °C, the 110Si reaches 300 °C, and the 250DT and 450DT reach 500 °C.
A holding oven keeps dry electrodes dry between issue and use, at a relatively low temperature. Re-baking drives moisture back out of electrodes that have already been exposed, and needs a much higher temperature. In this range the 250DT and 450DT reach 500 °C and can re-bake; the portable quivers at 150 °C are holding ovens only.
The EL-OV-10Si holds 5 kg at 4.25 kg of its own weight, with a tilt stand, basket and insulated shoes. Where site voltage is uncertain, the 10Si-DTC accepts both 110 V and 220 V. For a larger crew, the 20Si holds 9 kg.
The portable models take electrodes up to 457 mm (10Si and 10Si-DTC) or 450 mm (20Si). The floor-standing ovens are sized by chamber dimensions — the 250DT chamber is 350 × 540 × 320 mm.
Yes. The 110Si, 250DT and 450DT all use digital temperature controllers and digital thermometers. The three portable models use analogue control. Where a procedure requires a recorded or verifiable holding temperature, specify a digital model.
