Safety Notes
General Safety Notes
•All equipment undergoes final inspection and testing before leaving our factory. However,
if equipment is damaged during shipping or through any other circumstances, it must not
be used in service. Please check the device regularly for damages. Damaged parts
should be replaced immediately.
•All power/air/water/gas sources should be rated for the demands of the device as listed in
the technical data sheets. Maximum ratings must not be exceeded. All VDE (Verein
Deutscher Elektro-Ingenieure) standards should be followed. Equipment should be
grounded according to standards.
•Adherence to valid regulations regarding necessary checks (e.g. according to Accident
Prevention & Insurance or electrical equipment) is exclusively taken over by the
buyer/user of this product.
•This device has been designated to be used only for its intended purpose. All other
applications must be prohibited for safety reasons as otherwise the manufacturer’s
warranty expires.
•The device may only be used by persons who have been instructed in the handling and
have been expressly commissioned with the operation.
•The device should be set-up in a clean, well-ventilated room, if necessary under a hood.
•Supporting surfaces should be straight, flat and adequately stable.
•Don’t place anything on top of the machine.
•To avoid injury, appropriate protection should be worn (e.g. gloves, safety glasses, safety
shoes, hearing protection etc.)
•If the machine is defective or working improperly it must be taken out of service. In case
of further use of the machine the owner will be held responsible for any consequential
damage.
•To prevent accidents from water, fire or explosion, all power/air/water/gas sources should
be turned off after working hours and during breaks, and secured against unauthorized
access.
•When carrying out maintenance works or repairs or when opening the device always turn
off the main power switch and unplug the whole unit.
•Repairs should be carried out only by the manufacturer or by qualified and certified
personnel appointed according to chapter 7 –warranty.
•In case of suspected ingress of liquid stop operation and contact Service.
•Check all hose joints for tightness, if necessary fasten clamps.

Specific Safety Instructions
•Never store explosive, highly inflammable or burnable material in the working area.
•Only put the hot crucibles, pestles and moulds on a heat-resistant and fireproof support.
•Only use the device for melting metals and alloys in the crucibles intended for this
purpose.
•Do not melt materials that produce toxic gases.
•Only switch on the generator with inserted melted material.
•Do not reach into the inductor chamber when the heater is on.
•Use pliers when inserting and removing the casting rings or melting crucibles. There is a
risk of burns.
•Only open the casting chambers if there is no overpressure or underpressure.
•Handle gas cylinders carefully, do not heat them and protect them from falling over.
•Alloys with a longer melting time are not permitted. The rest period between a casting
and the start of a new heating process must be at least 6 minutes. During this time, no
hot crucible should be in the device. Casting ring chamber and inductor chamber must be
open during this time for cooling reasons.
•Small metal quantities below 15 g are inaccurate and difficult to melt due to lack of mass.
If it comes to mishandling, often cause errors in embedding or a wrong temperature
assessment of the molten metal.
•Precious metal (EM) is usually cast in the graphite crucible, if necessary in the ceramic
crucible with the graphite crucible holder.
•When melting thin and few precious metal platelets, make sure that they do not stand
upright, otherwise no coupling takes place and the metal does not melt. Therefore push
the plates together, place old cast cones on the new material or weld or score the plates
together.
Pay attention to the maximum percentage of old material and shred it enough! The parts
must lie on the bottom of the pot, otherwise there is no or only partial metal melting.
•The heating process may include max. 3 minutes. Alloys with a longer melting time are
not permitted.
Note:
The machine must not be used by persons with electronically controlled medical
aggregates such as pacemakers.
