OVEN TYPE DESCRIPTION
Wiring
The dryWIRE® Oven is designed for AC Single Phase
Power Only.
Note: Oven is factory wired for 480V & can be rewired for
240V.
Grounding
The 240V / 480V dryWIRE® oven is equipped with a Green
Grounding Screw in the junction box.
Electrode Placement
See # IV. Shelving Adjustment & Spool Placement
Guide to Storage
Once flux cored wire is removed from its initial packaging,
the unused portion should be stored in a dryWIRE® Oven -
not to exceed 300°F (150°C) for coils or wire baskets,
*250°F (121°C) for fiberboard spools or *150°F (65°C) for
plastic spools. Never store wire in its original plastic bag.
Precise temperatures for wire storage and reconditioning
should be obtained from the wire manufacturers' technical
department.
*Note: Temperatures exceeding this will damage the spool
and render the wire un-usable.
Reconditioning
Flux cored wires exhibiting weld metal
porosity or "worm tracks" due to moisture absorption by the
flux can be reconditioned by rebaking the wire.
The exact time and temperature for rebake are determined
by the wire and the spool material. Wire coils, masonite
spools or wire baskets are typically rebaked in a range of
230°F-300°F (110°C -149°C) for a minimum of 6 to 12 hours.
Wire on plastic spools can not be rebaked, because of plas-
tics inability to withstand high temperature. Precise temper-
atures for wire storage and reconditioning should be
obtained from the wire manufacturers' technical department.
Another important factor in the storing and rebaking of flux
cored wire is the lubricant on the outside of the wire. Some
lubricants can be damaged by high temperatures - contact
the wire manufacturer for possible damage.
Venting
For normal holding operations set adjustable vent on the
door about 1/4 open.
Temperature Setting
The temperature range of a dryWIRE® oven is 100° to
550°F (38° to 288°C). The thermostat dial is calibrated from
100° to 550°F (38° to 288°C). Required oven temperature
setting is obtained by rotation of the dial to line up desired
temperature with the indicator light.
The indicator light only operates when voltage is applied to
the twin heating elements. Momentary rotation past desired
temperature setting may be necessary to activate the pilot
light in order to locate it for indexing purposes.
Thermostat is accurate to +/- 25°F (14°C) at the sensing
bulb located inside the oven. However, because this is a
gravity convection type oven, temperatures may vary at dif-
ferent areas in the oven.
