Common problems and cause analysis: problem phenomenon, cause analysis, solution, weak welding (bite mark) the welding temperature is too low, adjust to the appropriate welding temperature, the flux is not sticky or insufficient, add enough flux, the welding rod ear is not clean, the welding rod ear is clean, the mold temperature is insufficient, the preheating time is prolonged, the air pressure is adjusted, the bus bar is not smooth, the air hole, lead wire and flux are excessive, and the flux is sucked dry, The pole lug is too long, the pole lug is cut, there are pores in the pole lug part, the pole lug has been melted, the temperature is too high, adjust to the appropriate welding temperature, the preheating time of the lower mold is too long, the casting welding time is too long, the casting welding time is too long, the casting welding time is too long, the bus or components are not formed, the cooling water quantity is insufficient, the water quantity is sufficient, the cooling water pump fails, the cooling water pump is replaced or repaired, and the cooling method is improper Adjust the cooling mode, pull rod deformation, etc., or the cooling parameters of pull-off rod group (difficult to demould) are inappropriate, adjust the cooling mode and mode, the air pressure is not enough, increase or adjust to the appropriate pressure, poor demoulding, spray release agent, rod lug welding is not in place, adjust rod lug or replace bad rod plate, tin content is insufficient, the preheating time of tin (tin content is 1-1.5 g) mold is too long, shorten the preheating time, During use, press the start button to stop operation. If the actual temperature is lower than the minimum temperature, adjust the minimum temperature or wait for the temperature to rise.
Special welding auxiliary equipment for positioner is suitable for welding positioner of rotary work to obtain ideal machining position and welding speed. The welding operator is generally composed of columns, beams, slewing mechanisms, trolleys and other components. A device that sends and maintains the welding head or welding gun at the position to be welded, or moves the flux along the specified track at the selected welding speed. CNC cutting machine uses digital program to drive the movement of the machine tool. When the machine tool moves, the random cutting tool is equipped to cut the object.
Press the start button for less than 0.5 seconds, press the start button for more than 0.5 seconds, press the emergency stop button to turn out the reset equipment or eliminate foreign matters, then reset the travel sensor, move the travel sensor, return the travel sensor to the original position, the travel sensor is damaged, replace the sensor, press any key not to run, the air source is not opened or the air pressure is not enough, open or adjust the air pressure, If the actual temperature is lower than the minimum temperature, adjust the minimum temperature or wait for the temperature to rise, the computer board freezes, turn off the power and restart, the temperature does not rise, the electric heating pipe is damaged, replace the electric heating pipe, the water level of the water tank is higher than the mold water inlet or the solenoid water inlet valve is damaged.
