For AC precision spot / Series / Fusing welding: MIB-300A/600A
Use AC transformer and improve heat efficiency.
Reduce magnetize and peltier effect on work piece.
Features
- ■ Able to keep on using AC welder transformer if you already have
-
No need to buy new weld head and transformer if you are already using AC welder for production
- ■ Reduce burn of coating materials while fusing
-
-
- ■ Reduce slant abrasion of electrode and unequal size of welding nugget
-
Reduce slant heat on one material while welding different material (peltier effect), reduce slant abrasion of electrode and unequal size of welding nugget.
- ■ Reduce magnetize of work piece around electrode
-
Reduce magnetic material around welding current being magnetized.
- ■ Add secondary constant current control
-
Since welding current will be monitored and controlled directly, able to have higher current control than primary constant current control.
- ■ Increase number of maximum pulsation
-
Previous unit: 9 times pulsation maximum → MIB-300A/600A: Maximum 20 times for each WELD1 to WELD3
Since it suppresses the rapid heating to the work by repeating the welding time and the pause time, it becomes easier to control the amount of displacement compared with continuous welding for a long time. - ■ Able to set interrupt, up slope and down slope for all waveform (WELD1 to WELD3)
-
Interrupt function (Stop current when displacement value reaches to set level, go on to next step) will avoid work piece to be squashed, able to have more precise setting for welding condition.
