Safety measures and instructions

Please read these safety in-
structions carefully!
Failure to observe these safety
instructions can lead to seri-
ous injury and/or damage to the
product .
‰ Only operators with relevant knowledge of
arc welding should use this product
‰ Arc welding can injure eyes, burn skin and
cause hearing damage.
‰ Therefore:
Use welding shield with filter com-
plying with respectively the EN 175
and EN 379 standards
Wear proper protective clothing
and ear protection
Make sure others are protected
(e.g. curtains) from arc rays and
flashing
‰ Remove all combustible materials – in-
cluding liquid and gaseous fuels, cloth,
sawdust, wood, paints and solvents - from
the work area or completely cover the ma-
terials with a protective non-flammable
covering. Fire extinguishing equipment
should be ready at hand for instant use.
Pay attention to spatter/dross created dur-
ing welding; sparks can cause fire several
hours after welding has finished!
‰ Work pieces must be completely cleaned
so that no substances on the material,
such as chlorinated solvents, can produce
flammable or toxic vapours. Do not weld
containers that have held combustibles.
‰ Always check cables before operating the
machine. Defective cables may cause in-
jury and/or fire.
‰ Do not make temporary repairs; repairs
should be made by qualified personnel.

Safety measures and instructions
‰ Do not pull cable assembly across sharp
edges or expose to welding spatter or hot
surface
‰ To prevent electric shock, isolate yourself
by using proper protective clothing and in-
sulating mats. DO NOT wear wet clothing.
‰ Do not exceed power rating. Overload can
lead to torch damage, destruction and/or
injuries.
‰ Turn off primary power before working on
torch parts and/or replacing consumables.
‰ Do not breathe fumes or gases from weld-
ing. Welding fumes are harmful; lead,
cadmium, copper, zinc, mercury, stain-
less steel, galvanised steel and beryllium
in particular. Therefore, use ventilation or
an extraction system to ensure that Maxi-
mum Admissible Concentration of harmful
substances (MAC) level is not exceeded.
‰ Use proper gas for the welding process
(argon or helium) and pressure reducing
regulator.
‰ Keep cylinders in an upright position.
When not in use, keep cylinder valves
closed. Keep cylinders away from heat,
sparks or flame.
‰ Follow the pressurised gas manufactur-
er's operating instructions for mounting
the regulator to the gas cylinder.
