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.

自動直縫焊機要平整的放在平地上，如果要靠近墻體安裝，要距離墻體2米左右的距離，確保機箱門能打開，為以后焊接的維修留有足夠的空間，位置選好后，要用膨脹螺絲來固定自動直縫焊機。

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.

需要大量的氣壓來驅動氣缸的工作，給電極以壓力。要有良好的氣壓供應，氣壓不足的情況下，焊接易造成電極壓力不足，焊接過程中出現(xiàn)炸火，飛濺等現(xiàn)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.

自動直縫焊機二聯(lián)體的一個杯中要加入潤滑油，給電磁閥加油，確保電磁閥的靈敏性不受影響。氣缸的缸體也有注入油的位置，建議每周注油一次，過多會隨缸徑溢出。

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.

采用水冷的方式對焊機的變壓器、可控硅進行降溫，溫度過高，會影響焊接質量的穩(wěn)定。要有良好的冷卻系統(tǒng)，根據(jù)焊接功率及實際操作使用電流的大小，工業(yè)冷水機制冷效果好，能較快帶走焊接過程中所產生的熱量，確保自動直縫焊機焊接質量的穩(wěn)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.
