General equipment adopts three-phase five wire connection mode, three live wires, one zero wire and one ground wire. The diameter of three live wires should be at least 25 m2 copper wire to ensure the input of instantaneous high current. The zero line and ground line should not be the same line, but should be connected separately. The ground wire should be connected, otherwise it is easy to burn the board.

自动直缝焊机要平整的放在平地上，如果要靠近墙体安装，要距离墙体2米左右的距离，确保机箱门能打开，为以后焊接的维修留有足够的空间，位置选好后，要用膨胀螺丝来固定自动直缝焊机。

The automatic straight seam welding machine should be placed flat on the ground. If it is to be installed close to the wall, it should be about 2 meters away from the wall to ensure that the chassis door can be opened, leaving enough space for future welding maintenance. After the position is selected, the automatic straight seam welding machine should be fixed with expansion screws.

需要大量的气压来驱动气缸的工作，给电极以压力。要有良好的气压供应，气压不足的情况下，焊接易造成电极压力不足，焊接过程中出现炸火，飞溅等现象。

A large amount of air pressure is needed to drive the cylinder and pressure the electrode. There should be a good supply of air pressure. Under the condition of insufficient air pressure, the welding is easy to cause insufficient electrode pressure, and the phenomenon of explosion and spatter occurs in the welding process.

自动直缝焊机二联体的一个杯中要加入润滑油，给电磁阀加油，确保电磁阀的灵敏性不受影响。气缸的缸体也有注入油的位置，建议每周注油一次，过多会随缸径溢出。

Add lubricating oil into one cup of the automatic straight seam welding machine, and add oil to the solenoid valve to ensure that the sensitivity of the solenoid valve is not affected. The cylinder block of the cylinder also has a place for oil injection. It is recommended to inject oil once a week. Too much oil will overflow with the cylinder bore.

采用水冷的方式对焊机的变压器、可控硅进行降温，温度过高，会影响焊接质量的稳定。要有良好的冷却系统，根据焊接功率及实际操作使用电流的大小，工业冷水机制冷效果好，能较快带走焊接过程中所产生的热量，确保自动直缝焊机焊接质量的稳定。

The transformer and SCR of the welding machine are cooled by water cooling. If the temperature is too high, the stability of the welding quality will be affected. A good cooling system should be provided. According to the welding power and the actual operating current, the cooling effect of the industrial chiller is good, which can quickly take away the heat generated in the welding process and ensure the stability of the welding quality of the automatic straight seam welder.
