To stop the mould in the correct position under the drain spout, the mould
guide is also equipped with an adjustable mould stop. Loosen the thumb
screw on the side of the mould stop, and position it so that it will stop the
mould when the last sprue hole in the mould is centered under the drain
spout. When it is in the correct position, lock it in place with the thumb
screw.
When using the mould guide with a multiple cavity mould, the mould is set
onto the guide rails and slid forward until it touches the mould stop. The
cavity closest to the operator is filled first. The remaining cavities require vi-
sual alignment with the drain spout and are filled (each in order) as the
mould is slowly drawn towards the operator. When all cavities are filled,
allow the mould to rest on the guide for several seconds until the sprue so-
lidifies.
Operating Your Furnace
Plug in your furnace to turn it on. (Unplugging it will turn it off.) Up to 25
pounds of cold bullet metal can be added to the pot. Note: before using
your new furnace for the first time, we suggest you turn it on when empty
and set the furnace for the desired temperature. Then allow it to run for 10
to 15 minutes in a well-ventilated area (better yet, outdoors) to burn off pro-
tective oil. The unit usually smokes a bit at first which could be a problem
inside your house.
The Mag 25 furnace is equipped with a multi-function digital temperature
controller. The controller has two temperature displays. The lower display
marked “SV” (set value) is the temperature that the furnace is programmed
to run at.
