MMA welding

CAUTION

Risk of being crushed or burnt.
When replacing spent or new stick electrodes

•  Switch off machine at the main switch
•  Wear appropriate safety gloves
•  Use insulated tongs to remove spent stick electrodes or to move welded workpieces and
•  Always put the electrode holder down on an insulated surface.

Shielding gas connection!
During MMA welding open circuit voltage is applied at the shielding gas connection
(G¼" connecting nipple).

• Place yellow insulating cap on the G¼" connection nipple (protects against electrical

voltage and dirt).

Connecting the electrode holder and workpiece lead

CAUTION

Shielding gas connection!
During MMA welding open circuit voltage is applied at the shielding gas connection
(G¼" connecting nipple).

• Place yellow insulating cap on the G¼" connection nipple (protects against electrical

voltage and dirt).
