4_OPERATING INSTRUCTIONS
PLACEMENT AND TESTING
COATED ELECTRODE WELDING (MMA)
Note: The electrode is mostly connected to the positive
terminal (reverse polarity). In some determined
circumstances though, it should be connected to
the negative terminal (direct polarity), as it usually
happens with the basic electrode. Refer to the electrode
documentation to be assured.
TIG WELDING
MIG/MAG WELDING
TOOLS REPLACEMENT
MMA PROCESS (COATED ELECTRODE)
TIG PROCESS
Do not use nor sharpen thorium doped tungsten
electrodes due to the moderate radioactive activity risk
of the material. You will be able to recognize the thorium
dioxide presence and concentration by its indicative
strap on the electrode, according to EN ISO 68848:2004
(colors: yellow, red, purple and orange). Avoid these
electrodes and use substitutes with no content. For
example, lanthanum and cerium derived electrodes
(straps: black, grey, blue, gold) which do not show
radioactive activity.
