cause fires. Keep a fire extinguisher nearby and
someone watching who can use it immediately.
Do not weld on drums or any closed containers.
d) Danger from welding arc radiation: Welding arc
radiation can damage your eyes and injure your
skin. Wear a hat and safety goggles. Wear ear
protection and a high, closed shirt collar. Use a
welding helmet and filters of the correct size.
Wear complete body protection.
e) Danger from electromagnetic fields: Welding
current creates electromagnetic fields. Do not use
together with medical implants. Never wind the
welding cables around your body. Guide welding
cables together.

5. Welding preparations

Connect the earth terminal (-) (2) direct to the part to
be welded or to the support on which the part is
resting. Ensure that the earth terminal (-) is in direct
contact with the part to be welded. You should
therefore avoid coated surfaces and/or insulated
materials. The electrode holder cable has a special
clamp at one end, which is used to secure the
electrode. The welding safety shield must be used at
all times for welding. It protects your eyes from the
radiation emitted by the arc and nevertheless
enables you to watch the welding process (not
included in items supplied).
6. Welding
After you have made all the electrical connections for
the power supply and for the welding circuit, you can
proceed as follows:
Insert the unsheathed end of the electrode into the
electrode holder (1) and connect the earth terminal
(-) (2) to the part you wish to weld.
Ensure that a good electric contact is made.
Switch on the welding set at the switch (4) and set
the welding current using the hand wheel (3) to suit
the electrode you wish to use.
Hold the safety shield in front of your face and rub
