Frequently Asked Questions - KD-1151 Vevor

What is the power supply voltage of the Vevor KD-1151 furnace?

The Vevor KD-1151 furnace operates at a voltage of AC 120 V at 60 Hz.

What maximum temperature can this furnace reach?

The maximum temperature is 1150 °C (2102 °F). Never exceed this limit.

What metals can be melted with the supplied crucible?

The supplied crucible is suitable for melting precious metals such as gold, silver, copper, aluminum, zinc, lead, tin, magnesium, and calcium. For other metals, purchase a suitable crucible.

How to adjust the temperature?

Press the U key; the temperature number flashes. Use ▲ and ▼ to set the desired temperature, then press P to confirm. The heating symbol flashes at the top of the screen.

What to do if the furnace displays an error code?

Error codes are: ERR1 (temperature sensor), ERR2 (thermocouple), ERR3 (temperature out of range), ERR4 (internal sensor), ERR5 (fan), ERR6 (high temperature). Refer to the manual for corrective actions.

Is it necessary to let the furnace cool down after use?

Yes, after continuous operation, let the furnace cool for at least 3 hours. Never exceed 2 hours of continuous use; allow a 30 minute recharge time.

How to clean the furnace?

Unplug the device before cleaning. Wipe surfaces with a damp microfiber cloth. Never use chemical cleaners. Avoid moisture entering the interior.

Can I melt other metals than those listed?

Yes, but you must use a crucible suitable for the metal's melting point. Research the vapors produced and ensure adequate ventilation. Never fill the crucible to more than 80% of its capacity.

What to do if the heating wire is burnt?

If after pressing P the heating symbol flashes but the temperature does not rise within one minute, the heating wire is likely burnt. Purchase a replacement heating wire cylinder.

What are the essential safety precautions?

Use a grounded power source, keep a 12 inch clearance around the furnace, wear ASTM F2675 certified gloves, maintain ventilation of at least 4 air changes per hour, and never leave the furnace unattended during operation.

INSTRUCTIONS FOR METALS MELTING

IMPORTANT: The crucible is only adapted to melt gold, silver, copper and noble metals!

List of the metal types which can be molten in the crucible provided with the device:

Metal	Symbol	Density	Density Fusion Point
Copper	Cu	8.92g/cm3	1084.62°C(1984°F)
Silver	Ag	10.49g/cm3	962.78°C(1763.2°F)
Gold	Au	19.3g/cm3	1064.18°C(1947.52°F)
Aluminum	Al	2.7g/cm3	660.32°C(1220.58°F)
Magnesium	Mg	1.74g/cm3	650°C(1202°F)
Zinc	Zn	7.14g/cm3	419.53°C(787.15°F)
Lead	Pb	11.34g/cm3	327.5°C(621.5°F)
Tin	Sn	7.28g/cm3	231.93°C(449.47°F)
Calcium	Ca	1.55g/cm3	842°C(1548°F)

Please consider that the crucible shouldn't be completely filled to reach optimal result. If you overfill the crucible, the device won't be able to produce the heat needed to let the metal melt. Moreover, the melting process often produces vapors. If you overfill the crucible, it can lead to overpressure and the use of the device gets dangerous for the user, especially when opening the cover.

Please buy an adapted crucible to melt other metals. Always inform yourself about the production of vapors during the melting process to check the compatibility of the device with your intentions.

MATTERS NEEDING ATTENTION

Display error codes to determine machine problems.

• ERR1: The temperature measuring circuit on the board is broken.
• ERR2: The thermocouple is broken or not connected.
• ERR3: Thermocouple temperature measurement is out of range.
• ERR4: The temperature sensing element on the board is broken or faulty.
• ERR5: The fan is broken or falls off.

ERR6: The temperature control element is high.

NOTE:

1. Metal material falling into the heating wire cylinder can cause a short circuit. In work, if the crucible breaks, metal flow can burn the heating wire cylinder. In that case, you need to buy a replacement heating wire cylinder.
2. After pressing the P key, the upper right corner flashes on the heating bed. If it does not heat up within one minute, it can be judged that the heating wire is burned out.

MAINTENANCE

1. Clean the exterior and interior regularly to avoid impurities and residues.
2. Before and after use, check whether the device is functioning properly.
