SAFETY §1 SAFETY §1.1 Signal Explanation The above signals mean warning! Notice! Running parts and getting an electric shock or thermal parts will take damage for your body or others. The corresponding notices are as follows. It is quite a safe operation after taking several necessary protection measures. - Page 4 SAFETY condition. Replace damaged insulation. Never dip the electrode in water for cooling. Never simultaneously touch electrically “hot” parts of electrode holders connected to two welders because voltage between the two can be the total of the open circuit voltage of both welders. ...
- Page 5 SAFETY engine parts and igniting. Do not spill fuel when filling tank. If fuel is spilled, wipe it up and do not start engine until fumes have been eliminated. WELDING SPARKS can cause fire or explosion. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire.
