1、切割應(yīng)從邊緣開始;盡可能從邊緣開始切割，而不要穿孔切割。采用邊緣作為起始點(diǎn)會(huì)延長消耗件的壽命，正確的方法是將噴嘴直接對(duì)準(zhǔn)工件邊緣后再啟動(dòng)等離子弧。

1. Cutting shall start from the edge; Cut as far as possible from the edge rather than through the hole. Using the edge as the starting point will prolong the service life of the consumable parts. The correct method is to directly align the nozzle with the edge of the workpiece and then start the plasma arc.

2、減少不必要的“起弧(或?qū)Щ?”時(shí)間;起弧時(shí)噴嘴和電極的消耗都非?？?，在開始前，應(yīng)將割炬放在切割金屬行走距離內(nèi)。

2. Reduce unnecessary "arc striking (or pilot)" time; The consumption of nozzle and electrode during arc striking is very fast. Before starting, the cutting torch should be placed within the walking distance of cutting metal.

3、噴嘴不要過載使用;讓噴嘴過載(即超過噴嘴的工作電流)，將使噴嘴很快損壞。電流強(qiáng)度應(yīng)為噴嘴的工作電流的95%為宜。例如:100A的噴嘴的電流強(qiáng)度應(yīng)設(shè)定為95A。

3. Do not overload the nozzle; Overloading the nozzle (that is, exceeding the working current of the nozzle) will quickly damage the nozzle. The current intensity should be 95% of the working current of the nozzle. For example, the current intensity of 100A nozzle should be set to 95A.

4、山東數(shù)控焊接設(shè)備廠家建議這里要采用合理的切距;按照使用說明書的要求，采用合理的切距，切距即切割噴嘴與工件表面的距離，當(dāng)穿孔時(shí)，盡量采用正常切距的2倍距離或采用等離子弧所能傳遞的大高度。

4. Shandong CNC welding equipment manufacturer suggests that reasonable cutting distance should be adopted here; According to the requirements of the operation manual, use a reasonable cutting distance, which is the distance between the cutting nozzle and the workpiece surface. When piercing, try to use the distance of 2 times of the normal cutting distance or the large height that can be transmitted by the plasma arc.

5、穿孔厚度應(yīng)在機(jī)器系統(tǒng)的允許范圍內(nèi);切割機(jī)不能在超過工作厚度的鋼板上穿孔，通常的穿孔厚度為正常切割厚度的1/2。

5. The perforation thickness shall be within the allowable range of the machine system; The cutting machine cannot perforate the steel plate exceeding the working thickness, and the normal perforation thickness is 1/2 of the normal cutting thickness.

6、盡量保持?jǐn)?shù)控切割機(jī)割炬和消耗件清潔:在割炬和消耗件上的任何臟物都會(huì)大大地影響等離子系統(tǒng)的功能。更換消耗件時(shí)要將其放在干凈的絨布上，要經(jīng)常檢查割炬的連接羅紋，用過氧化氫類清潔劑清洗電極接觸面和噴嘴。

6. Try to keep the cutting torch and consumable parts of the CNC cutting machine clean: any dirt on the cutting torch and consumable parts will greatly affect the function of the plasma system. When replacing the consumable parts, put them on a clean flannelette, check the connection rib of the cutting torch frequently, and clean the electrode contact surface and nozzle with hydrogen peroxide detergent.

7、盡量少穿孔切割，穿孔是鋼水反濺會(huì)傷及噴嘴，這是割嘴損壞的主要原因之一，如果一定要穿孔切割，在穿孔處用鉆頭打預(yù)鉆孔，在從預(yù)鉆孔處開始切割;

7. Try to cut as few holes as possible. Perforation is one of the main reasons for the damage of the cutting nozzle due to the back-splashing of molten steel. If it is necessary to cut holes, use a drill bit to drill holes in the hole and start cutting from the hole;

8、盡量在切割機(jī)額定的正常切割厚度范圍內(nèi)切割，盡量不要在極限切割厚度上切割，國產(chǎn)切割機(jī)的正常切割厚度一般是生產(chǎn)廠家標(biāo)注的大切割厚度的60%，盡量在這個(gè)厚度范圍內(nèi)切割，就能保護(hù)割嘴;

8. Try to cut within the rated normal cutting thickness of the cutting machine, and try not to cut beyond the limit cutting thickness. The normal cutting thickness of the domestic cutting machine is generally 60% of the large cutting thickness marked by the manufacturer, and try to cut within this thickness range to protect the cutting nozzle;

9、割嘴到鋼板的距離盡量保持恒定，一般在3-8mm左右，太遠(yuǎn)了不但耗電量太大，切割穿透能力力會(huì)下降，而且相對(duì)比較消耗電極，使電極使用壽命下降;太近了那更簡單，非常費(fèi)噴嘴，噴嘴的使用壽命會(huì)成倍的下降，甚與上去即被燒掉。

9. The distance from the cutting nozzle to the steel plate should be kept as constant as possible, generally about 3-8mm. If it is too far away, it will not only consume too much power, but also reduce the cutting penetration ability, and relatively consume the electrode, which will reduce the service life of the electrode; If it is too close, it will be simpler and very expensive. The service life of the nozzle will be doubled, or even burned up immediately.
