6.9 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.
Warning – Risk from electrical current!
If welding is carried out alternately using different methods and if a welding torch and an
electrode holder remain connected to the machine, the open-circuit/welding voltage is applied
simultaneously on all cables. The torch and the electrode holder should therefore always be
placed on an insulated surface before starting work and during breaks.
Connection and welding leads (e.g. electrode holder, welding torch, workpiece lead, interfaces)
may only be connected when the machine is switched off.
Follow the safety instructions on the opening pages entitled “For Your Safety”!
We can only guarantee the perfect functioning of our machines when used with our range of
accessory components.
