product safely. Non-observance of the safety instructions may result in risks
to the life and health of personnel, environmental damage, or material
damage.
Observe the document entitled “Safety Instructions”.
2.1 Designated use
The EX-TRAFIRE®125HD may be used only for the purpose and manner
described. It is used only for the generation and control of the output
current required for plasma cutting, gouging, and marking. Any other use
is considered improper. Unauthorized modifications or changes to
enhance the performance are not permitted.
Do not exceed the maximum load data as defined by the document
supplied. Overloads lead to destruction.
Do not make any modifications or changes to this product.
Do not use the EX-TRAFIRE®125HD to thaw pipes.
Do not use or store the EX-TRAFIRE®125HD outdoors where it is wet.
DANGER
Describes an imminent threatening danger. If not avoided, it may cause
severe injury or death.
WARNING
Describes a potentially dangerous situation. If not avoided, this may
result in serious injury or death.
CAUTION
Describes a potentially harmful situation. If not avoided, this may result in
slight or minor injury.
NOTICE

EX-TRAFIRE®125HD 2Safety
EN - 7
2.2 Obligations of the operator
Ensure that only qualified personnel are permitted to work on the
EX-TRAFIRE®125HD.
Authorized personnel are:
— those who are familiar with the basic regulations on occupational
safety and accident prevention;
— those who have been instructed on how to handle the
EX-TRAFIRE®125HD;
— those who have read and understood these operating instructions;
— those who have been trained accordingly;
— those who are able to recognize possible risks because of their
special training, knowledge and experience.
Keep untrained persons out of the work area.
Each time the EX-TRAFIRE®125HD’s cover plates are opened, have
Thermacut®or another authorized specialist perform a safety inspection
in accordance with DIN IEC 60974 Part 4: “Periodic inspection and
testing”.
The EX-TRAFIRE®125HD can produce electromagnetic fields that could
impact the proper function of cardiac pacemakers and implanted
defibrillators.
Do not use the EX-TRAFIRE®125HD if you have a pacemaker or an
implanted defibrillator.
This Class A cutting device is not intended for use in residential areas with
a public low-voltage power supply system. It can potentially be difficult to
guarantee electromagnetic compatibility in these areas due to both
conducted and emitted interference.
The EX-TRAFIRE®125HD may be used only in industrial zones according
to DIN EN 61000-6-3.
2.3 Warning and notice signs
The following warning, notice and mandatory signs can be found on the
product:
