In order to ensure the normal and stable operation of the welding machine, the welding machine should be placed in a dry, dust-free, ventilated, humid and non-vibration place, and the temperature of the environment is best controlled between - 10 ~30 ~C, corresponding to the humidity can not exceed 65%, so when the overall environmental conditions can not reach the above mentioned. When required, it is likely to affect the operation of the welding machine, and if serious, it will cause faults to the welding machine and the welding controller.

In fact, the welding machine can be directly placed on the flat ground. If conditions permit, it is better to use the screw of the foot to fix the equipment. The main purpose is to improve the stability of the welding machine in work, but the equipment can not be lengthened at will, or the welding electrode arms of different specifications can be exchanged with each other to avoid fixing the equipment. The power of the welding machine and the effect of welding have an impact.

For the power supply used in the welding machine, it is necessary to select the required power supply voltage and frequency. If there are high frequency electrical equipment around the equipment, corresponding protection measures should be taken. If the power supply voltage fluctuates greatly, it may also affect the quality of the welding workpiece.
