在石油安装企业里,焊接工作是大量的。虽然大部分场合下是集中施焊,但总免不了某些特殊情况下的零星焊接,尤其在夜晚施焊时,照明便成了问题。在易于取得照明电源的场所,接几个照明灯并不困难,然而在选取照明电源或拉设照明线路都有困难的情况下怎么办呢?我们可以根据弧焊机的工作特性,从焊机上获取照明电源。一般使用的直流和交流焊机,其特性参数上都有个“空载电压”和“工作电压”,其空载电压值约为70V左右,这一“空载电压”就可以用作零星焊接场所的夜间照明电源。将两只36V、100W的灯泡(如使用24V灯泡则需3只)经串联后,直接接到焊机的两个输出端(即接电焊把线的那两个螺栓上),如图所示,开动焊机,灯泡就发亮了。施焊时,焊机次级
In the oil installation business, welding work is a lot. Although most occasions are concentrated welding, but always sporadic welding in some special cases, especially in the night when welding, lighting has become a problem. In the easy access to lighting power supply place, then a few lights is not difficult, but in the selection of lighting power supply or pull the lighting line has difficulty in how to do it? We can arc welding machine according to the characteristics of work, from the welder Get on the lighting power supply. Commonly used DC and AC welder, the characteristic parameters have a “no-load voltage” and “working voltage”, the no-load voltage value is about 70V, the “no-load voltage” can be used for sporadic welding Night lighting power places. The two 36V, 100W bulb (such as the use of 24V bulb will need 3) connected in series, directly to the welding output of the two (that is, the welding wire to the two bolts), as shown , Start the welder, light bulb on the shiny. When welding, welder secondary
