What are the safety inspection before using electric torch welding machine?
Inspection prior to use of electric welding machine:N1, before use, should clean up the scene, do a good job to prevent falling objects and objects falling down protection work;N2, the welding around (especially below) whether there is flammable and explosive goods, if there is, should maintain a certain safety distance, if cannot reach the safe distance, should take other protective measures;N3, the protection of the ground (or protection of zero line) connection is correct, firmly rely on;Does the rated voltage of the N4 and welding machine match the supply voltage?;Does the capacity of the N5 and welding machine meet the requirements?;N6, insulated wire should be intact, contact resistance should be small and reliable contact (especially electric welding machine secondary);N7, the large capacity gas or water machine, check whether there is leakage of the welding machine adopts Water Leakage; fan strong cold, should check the direction of rotation of the fan is normal; the electric drive ventilation or dynamic AC arc welder reactor core, the first time the power is turned on, must pay attention to the turning of the motor is correct;N8, for long-term unused welding machine, should do insulation testing, qualified before use. N8, for long-term unused welding machine, should do insulation testing, qualified before use.
Inspection of hand-held power tools:N1, shell, handle with or without rupture;N2, the protection of the ground (or protection of zero line) connection is correct, firmly rely on;Is the soft cable (or flexible cable) in good condition for the N3?;N4, the plug is intact;N5, switch action is normal, flexible, whether there is no defect, rupture;Is the N6 and electrical protective devices in good condition?;N7 is the tool rotating part flexible?;Does the rated voltage of the N8 and tools accord with the supply voltage?;N9, for long-term unused power tools, should first do insulation testing, qualified before use.
