Lyman Mini Mag Furnace Instructions Manual

							OPERATING INSTRUCTIONS FOR MINI MAG FURNACE
(2800200)-Furnace Only, (110V),
(2800220)-Furnace Only (220V)
CAUTIONS:
• Never allow moisture near molten lead as when introduced to lead, a volatile steam
explosion occurs and molten lead is sprayed not only out over immediate area but also
all over the bullet caster. This moisture could be introduced by a wet ladle or dipper, wet
lead added to the pot, condensation from overhead pipes or many other ways.
• In no case attempt to touch the furnace while in operation as all surfaces are extremely
hot.
• Always make sure unit is plugged into a properly grounded outlet.
• Never use the heating element as a handle to move the furnace as damage to the element
may result as well as serious injury may be suffered by the user.
• No casting should be done without the basic safety wear. This includes long pants, long
sleeve shirt, heat resistant gloves, eye protection and closed top shoes.
• Keep all flammable items away from casting area and do not operate unit on flammable
materials such as paper, wood or carpeting.
• Casting should be done in a well ventilated area. Avoid breathing fumes or dust that
come from the furnace.
• Keep children away from casting and reloading areas.
• Do not continue to cast if you are distracted.
• Do not smoke, eat, or drink while handling lead or casting.
• Do not run dry without lead. (except initial warm-up period)
• Always wash hands after handling lead.
• Use caution when adding bullet metal to furnace or pot containing molten metal to avoid
splashing.
Set-up Instructions
Before using your Mini Mag Furnace, position the metal stand on a solid, non-flammable
surface in a well ventilated area. In use, the melting pot will reach temperatures of over 700˚
F. Make sure there is nothing near the furnace which may be ignited by high temperatures. Be
certain to always use the metal stand that is provided with your furnace.
Place the furnace in the metal stand and plug in the electrical cord into a properly ground-
ed wall outlet. Before adding lead alloy for the first time, we suggest that the furnace be
allowed to heat up for ten to fifteen minutes empty. This will burn off the preservatives used
to prevent rust. Bullet metal can be added at this time and will take approximately 1/2 hour to
reach proper casting temperature. Your furnace will hold 8 lbs. of lead alloy.
OPERATING YOUR FURNACE:
NOTE: READ THE ABOVE CAUTIONS PRIOR TO OPERATION
The Mini Mag furnace is designed to hold the temperature of lead alloy to a proper level
throughout a casting session.
The Mini Mag Furnace is designed for dipper casting. For best results, fill the dipper with
lead alloy and place the spout of the dipper against the pouring hole in the mould’s sprue
plate. Holding the mould and the dipper together, slowly turn them to a vertical position with
the dipper above the mould.WARNING! See Safety

							WARNING:Melting lead and casting lead objects will expose you and others in the area to
lead, which is known to cause birth defects, other reproductive harm and cause cancer.
REDUCING EXPOSURE:Lead contamination in the air, in dust, and on your skin is invisi-
ble. Keep children and pregnant women away during use and until cleanup is complete.
Risk can be reduced but not eliminated with strong ventilation, washing hands immediate-
ly after use of these products before eating, drinking or smoking, and careful cleaning of sur-
faces and floors with disposable wipes, after lead dust had had a chance to settle. Use a lead
specific cleaner with EDTA, or a high-phosphate detergent (like most detergents sold for elec-
tric dishwashers) and bag used wipes for disposal.
