SAFETY INSTRUCTIONS….cont
Some metals and metal composites have the potential to be highly
toxic; always wear a face mask .
When using the welder always ensure the operator as well as those
in the area use a welding mask with the correct shade filter lens.
CAUTION:
The warnings and cautions mentioned in this user manual can not
cover all possible conditions and situations that may occur. It must be under-
stood by the operator that common sense and caution are factors which can-
not be built into this product, but must be applied.
Vapours from chlorinated solvents can be decomposed by the heat of the arc
(or flame) to form phosgene a highly toxic gas and other lung and eye-irritating
products. The ultra violet (radiant) energy of the arc can also decompose tri-
chloroethylene and perchlorethylene vapours to form phosgene.
DO NOT
WELD
or cut where solvent vapours can be drawn into the welding atmosphere,
or where the radiant energy can penetrate to atmospheres containing even
minute amounts of trichloroethylene or perchlorethylene.

OPERATING INSTRUCTIONS….cont
Switch the welder on.
Set the required welding parameters as explained on pages 16, 17 & 18.
Fit the required electrode securely into the electrode holder.
Note:
Be aware that the electrode is now live, simply touching any part of
the workpiece will create a spark.
Place a face mask / helmet over your face (not supplied).
Initiate the arc; How the arc is initiated will depend on which setting have been
used when setting the welding parameters.
When the arc is created, proceed steadily in one direction keeping the gap
between the electrode and the workpiece constant.
When the weld is complete simply remove the electrode from the workpiece.
Remove any excess weld / slag with a wire brush / hammer (not supplied).
Once all work has been done, switch the machine off.

Caution:
Ensure all protective equipment is worn and bystanders are not in
the vicinity.
