【NEW】MM-140A Pulsed TIG Weld checker
【MM-140A】
“Visible” welding quality management for TIG welding is recommended!
Our TIG checker is a compact and user friendly design with an encoder.
- 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
We must measure and manage above factors.
*1: Available for touch-start welding.
*2: Our recommended flow rate sensor and input connector are connected.

- 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.
RS-C300-3000/RS-C050-3000（Cable length 3m） - 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. The model is PFM510-C6-2 (SMC).
Calibration of the sensor is not done by our company, thus, customers should prepare the sensor by themselves.

If flow rate sensor is not used, please note that items with ★ icons are necessary.
