    Welding machine precautions and maintenance 1. Safety points The welding machine is quipped with overcurrent and overheat protection circuits.When the gird voltage,output current and internal temperature exceed the set standard the welding machine will automatically stop working,but excessive use(such as excessive voltage) will still lead to welding,The machine is damaged,so you still need to pay attention to the following: ...
  • Page 37  It is forbidden to use the welding machine for thawing pipes。  The back of each welding machine is attached with a ground screw, and marked with a ground mark. Before use, select a cable with a section greater than 2.5mm2 and ground the welding machine shell reliably to release static electricity or prevent accidents that may occur due to electricity leakage.
  • Page 38 in dry condition. 3. Before maintenance Warning： Blind experiments and imprudent overhaul could lead to the expansion of failure,and ！ difficulty for a formal maintenance.Electronic equipment in the state of the exposed part of a voltage can lead to dangers.any direct or indirect contacts may lead to electric shocks incidents,and serious electric shock will cause death!!! Attention：During the warranty period, if not allowed by this Company, if there is any wrong maintenance to any fault of the welding power source, the suppliers will not provide free repairs.
