在CO_2气体保护焊中,经常会遇到一些麻烦事,如焊接时电流与电压的配合不当;网路电压的波动影响焊接电源的输出电压。采用一元化调节,对于克服上述问题具有重要意义。一元化调节,可以保证焊接时电流与电压经常处于最佳配合状态,同时在很大程度上消除焊接电源网路补偿不良所造成的影响。 In CO 2 gas shielded welding, often encounter some troublesome, such as welding current and voltage with the improper; network voltage fluctuations affect the welding power output voltage. The use of a unified adjustment, to overcome the above problems is of great significance. The unitary adjustment ensures that the welding current and voltage are always in the best condition, and at the same time, the influence caused by the poor compensation of the welding power network is largely eliminated.
