MM-140A

Checker for pulsed TIG welding is debut!
“Visible” welding quality management will be achieved!
Compact design and standing type.
Weld checker to measure current / voltage / time / gas flow rate in pulsed TIG welding.
Upper / Lower limit judgement is available.
Features
- ■ Measurement and judgement of necessarily monitoring factors for TIG welding are possible.
-
Upper / Lower limits of judgement and data management of factors are possible.
Welding quality is effected by below factors.- Current : the most important factor for welding.
- Voltage : It can be a factor that provides voltage-noise against welding point or peripheral devices.*1
- Time : important factor for welding as well as current.
- Shield-gas flow : it's necessary to discharge an arc stably.*2※2
We must measure and manage above factors.
*1: Available for touch-start welding.
*2: Our recommended flow rate sensor and input connector are connected.

Please ask for our pulsed TIG welders, too - ■ Measuring of long-time welding
- Maximum measurement time is 9999ms, thus, it’s available for long-time pulsed TIG welding.
- ■ Able to measure even while modulation function is operated.
- The modulation function is used to suppress welding faults such as blowholes.
In case of using complex waveforms control function, it enables to measure and judge each factors. - ■ Ethernet communication
- With connecting PC through LAN cable (Ethernet), uniform management is available.
The product offers one way and two way communications. In case of two way communication, reading/writing of measurement settings and data are possible. - ■ Accessaries (Options)
-
- Current sensor
Two types of sensors are on line-up. The one is used for detecting max. 50A and the other one is used for detecting max. 300A. Customers need to choose suitable sensor. - Torch voltage detecting cable (length 3m)
SK-1202980 - Relay cable (length 0.2m)
SK-1202967 - Flow rate sensor cable (length 3m)
SK-1202981 - Flow rate sensor
Please use our recommended product.
Calibration of the sensor is not done by our company, thus, customers should prepare the sensor by themselves.
