In order to ensure the normal operation of the welding machine, the welding machine should be placed in a dry, dust-free, ventilated, vibration-free, acid-alkali salt-free corrosion and moisture-free environment. The temperature of the whole environment should be guaranteed between-10 -+30 C, and the humidity can not exceed 65%. If the environment can not meet the above requirements, it will directly affect the welding. The normal operation of the welding machine, if serious, will also lead to the failure of the controller of the welding machine. The main machine in the welding machine can be installed on the flat ground. If conditions permit, it is recommended that the foot screw should be used to fix the machine. The purpose of this is to improve the stability of the welding machine. It is not possible to change the welding electrode arm at will, so as to avoid unnecessary influence on the welding power and the welding effect.

The power supply used by welding machine should meet the requirements of frequency and power voltage. If there are high frequency electrical equipment beside welding machine, corresponding protective measures should be taken, or if the power supply voltage fluctuates in a larger range, it will also have a serious impact on the quality of welding work piece. As we all know, welding machine The power of welding itself is relatively large, so it is necessary to install the power cord and switch of the brake knife according to the regulations. It is better to protect the welding machine from overload and leakage separately. The switch of the brake knife can not be used arbitrarily instead of the fuse of the insurance. Otherwise, when the welding machine breaks down, it will not be able to play a corresponding protective role. Even the transformer and control part of the welding machine will be burnt down.
