PRIOR TO USE
Unpack and check the inverter for any damaged or missing parts.
Contact your retailer immediately if this is the case.
Warning
: ensure that the inverter in not connected to a power source
before assembling, connecting or disconnecting cables.
Warning
: failure to follow electrical safety instructions will affect the
operating performance of your inverter and may damage the integral
safety system, which could result in a serious injury or fatality.
ARC Welding
When ARC welding the electrode holder cable is normally connected
to the positive (+) terminal
Work clamp connection
The work clamp cable is connected to the inverter terminal not
occupied by the electrode holder cable. The clamp is connected to
the work piece.
OPERATING INSTRUCTIONS
Warning
: always use a welding mask or helmet and welding
gauntlets to protect the eyes and avoid exposing skin to harmful
ultraviolet radiation and heat given off by the electric ARC. Ensure
that this protection is in place before striking an ARC.
ARC Welding
Strike the electrode against the work piece as if you were striking a
match.
DO NOT
hit the electrode against the work piece as this will
damage the electrode.
As soon as the ARC is ignited, a distance equal to the diameter of
the electrode being used should be maintained as a constant for
the duration of the weld, as the weld advances along the work piece
the angle of the electrode head must be kept at between 20 and 30
degrees.
At the end of the weld bead bring the electrode head backwards in
order to fi ll the weld crater, quickly lift the electrode head from the
weld pool to extinguish the ARC.
MAINTENANCE
Warning
: Disconnect the inverter from the power supply and wait for
the circuit light to go out before attempting to open the unit.
Remove the cover from the inverter on a regular basis and remove
dust by passing a low pressure air fl ow through the inside. The cover
should be correctly and securely replaced before attempting to use
the inverter. Keep the outside cover of the inverter clean at all times
by wiping with a soft dry cloth.
TROUBLESHOOTING
Should you experience any problem with the inverter please make
the following checks:-
• That the welding current is correct for the diameter and type of
electrode in use.
• That if the power supply is on, the power indicator light (green)
is on. If the power indicator light is not on there is a power supply
problem (for example a circuit breaker may have blown).
• That the correct voltage is being used as indicated on the
rating plate.
• That the (red) LED is not illuminated. If the LED is illuminated it
indicates an over or under voltage or a short circuit.
• That the normal intermittence ratio is correct and that the fan is
working correctly.
• That the cables are undamaged and that there is nothing causing a
short circuit.
• That all circuit connections are correct. You should pay particular
attention to the work clamp, making sure that it is correctly attached
to the work piece and that there is no grease, paint or other
contaminate that could cause a bad connection.
Electromagnetic Compatibility
This equipment is in conformity with the European standard on the
electromagnetic compatibility of ARC welding equipment and similar
processes (ARC and Plasma cutting)
Protection against interference (
E.M.C
.)
The emission limits in this standard may not provide full protection
against interference to radio and television reception when the
equipment is used closer than 30m to the receiving antenna. In
special cases, where highly susceptible equipment is used in close
proximity additional mitigation measures may be required to reduce
the electromagnetic emissions. Potential diffi culties may arise in
achieving electromagnetic compatibility in a non-industrial
environment (for example in a residential area). The user is
responsible for installing and using this equipment according to these
instructions. If electromagnetic disturbances are detected then it
shall be the responsibility of the user of the equipment to resolve the
situation.
