01、当焊丝端头始终有滴状金属小球存在,且过度频率偏低,此情况说明焊接电压偏高,此时应加快焊丝速度或降低焊接电压。
01, when the end of the welding wire is always dripping metal ball, and the frequency is too low, this indicates that the welding voltage is high, so we should speed up the welding speed or reduce the welding voltage at this time.
02、当焊丝干伸偏短时能正常焊接,稍长就出现顶丝现象,说明焊接电压偏低,此时应通过降低送丝速度或升高焊接电压。
02, when the welding wire's dry extension is short, it can be welded normally. The phenomenon of top wire appears at a longer time, which indicates that the welding voltage is low. At this time, we should reduce the wire feeding speed or increase the welding voltage.
03、调试焊接参数时应注意以下几点:
03. When the welding parameters are debugged, the following points should be paid attention to:
1.先把送丝速度调低点。
1. turn the wire feeding speed down.
2.再调焊接电压,焊接电流应根据焊接母材的厚度来控制。
2. the welding voltage should be adjusted, and the welding current should be controlled according to the thickness of the welded material.
3、再调送丝速度,这时把送丝调到正好(电弧能够把焊丝溶解,且溶解的很舒服)。听声音,看飞溅。如果溶解的很舒服,声音是很平稳的,不会乒乓作响,飞溅也少。
3, then transfer the wire speed, when the wire is transferred to the right (the arc can dissolve the wire, and dissolve very comfortably). Listen to the sound and see the splash. If the dissolved is very comfortable, the sound is very smooth, not ping-pong, spatter is less.
