allow you to use both hands to operate your power tool.
Keep your balance
• Don’t over reach, keep proper footing at all times to ensure
correct balance.
Maintain your power tool
• Keep your power tool in good working order, keep tools sharp and
clean for best and safest performance. Ensure ventilation holes are
kept clean and unrestricted at all times.
Always disconnect.
• Before changing tools, always ensure they are disconnected from
the power source.
Accessories
• The use of any attachment or accessory other than those
mentioned in this manual could result in damage or injury. The use
of improper accessories could be dangerous.
Never stand on your power tool
• Standing on your power tool or its stand could cause serious injury
if the tool is tipped or if the cutting tool is accidentally contacted. Do
not store materials above or near the tool so that it is necessary to
stand on the tool or its stand to reach them.
Switch off before connecting.
• Ensure the power tool is switched off before connecting to the
power source. If the power tool stops unexpectedly turn the power
switch to off.
Do not abuse the power cord.
• Be sure your cable/extension cable is properly wired and in good
condition. Always replace a damaged cable/extension cable or have
it repaired by a qualifi ed person before using it. Never yank or pull
the cable to disconnect it from the power socket. Never carry your
power tool by it’s cable. Keep the cable away from damp, heat, oil,
solvents, and sharp edges.
Check for damaged or missing parts.
• Before each use check if any part of the power tool is damaged or
missing, check carefully that it will operate properly and perform its
intended function. Check alignment of moving parts for binding. Any
guard or other part that is damaged should be correctly repaired or
replaced. Do not use if the power switch does not turn the power on

Additional safety information
IT IS THE RESPONSIBILITY OF THE OWNER AND OPERATOR
TO CHECK THE FOLLOWING.
• You must check electrical products before use to ensure
they are safe.
• You must inspect power cables, plugs, sockets and any other
connections for wear or damage.
• You must minimise the risk of electrical shock by the installation of
appropriate safety devices.
• A residual current circuit breaker should be incorporated in the main
distribution board. In addition a residual current device (RCD)
should be used. If in any doubt consult a qualifi ed electrician.
Warning
: If you intend to use this product with a generator care
should be taken. The generator
MUST
be stable with regards to
frequency, voltage and waveform. The output must be higher than
the power (KVA) of the inverter and the generator must be self
regulating. The use of a generator that is not self regulating may be
dangerous. If in any doubt do not use a generator with this product.
Danger
: Always unplug the inverter from the power source before
connecting or disconnecting cables or performing maintenance or
service. Direct contact with the inverter circuit is extremely
dangerous.
Always keep the inverter and cables in good working order and
condition. Immediate action should be taken to repair or replace
damaged parts or cables.
Keep the inverter clean.
Ensure work area is suitable and well ventilated; fumes produced in
welding are toxic and harmful.
Warning
: Cable connectors must be turned fully into the quick plugs
to ensure good electrical contact. Loose connection will cause
overheating, rapid deterioration and an overall loss of effi ciency.
Ensure that the fl ow of clean, cool air around the inverter is not
obstructed in any way. Make sure that there are no conductive dusts,
corrosive vapors or humidity that could enter the inverter and cause
serious damage.
Keep the working area free from any unrelated materials.
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.
It is particularly important to remove jewellery, watches, rings,
necklaces and loose fi tting clothing when welding.
Make sure that the work is secured correctly before operating the
inverter. Avoid any unintentional contact with the work. Accidental or
unintentional operation of the torch may be dangerous and will wear
the nozzle. Protect cables from heat and abrasive or sharp objects.
Keep unauthorized personnel away from the work area; any person
in the work area should use the same protective equipment as the
operator.
Operators must receive adequate training before operating the
inverter.
Warning
: when the inverter is switched off the short circuit light
will come on for approximately 10–15 seconds whilst the capacitor
discharges.
DO NOT
open the unit until the light has gone out.
Turn voltage switch to (0) off when inverter is not in use.
DO NOT
operate inverter if any cable or part is damaged.
DO NOT
use welding cables in excess of 10m in length.
DO NOT
connect the return cable to any metallic structure which is
not part of the work piece, this will impair weld quality and may be
dangerous.
DO NOT
use the inverter in damp or wet conditions or areas where
there is condensation. Under no circumstances get the inverter wet.
Danger
:
DO NOT
weld near fl ammable materials – solids, liquids
or gas.
DO NOT
weld containers or pipes which have held or may have
held fl ammable materials – solids, liquids or gas. Avoid operating
the inverter on materials cleaned with chlorinated solvents or near
solvents of this type.
DO NOT
touch the work until the weld has been allowed to cool
thoroughly as it will be very hot.
