AMADA WELD TECH Fine Spot Welders Pulsed Heat Controller


Particular heat control enables precision reflow soldering!

Pulsed heat controller controls pulsed current to obtain optimum heat for bonding multiple parts. This is suited for precision reflow soldering, ACF soldering and heat staking.


MR-130B pulsed heat controller controls pulsed current for heating to obtain ideal temperature to perform reflow soldering precisely. Real-time temperature feedback from a thermocouple attached to a thermode enables to adjust heat temperature in detail and precision performance according to the programmed heat profile can be done. MR-130B shows great performance also at ACF bonding and heat staking.

Precision real-time control
Controls heat temperature utilizing real-time temperature feedback from a thermocouple and heating time to perform in accordance with a programmed heat profile.

Precision real-time control

Large LCD
Displays both graphic and numerical data of setup values, measured values, waveforms, a schedule number and a program name all at once on a same screen.

Large LCD

Envelope limits
Displays in waveform both actual temperature and envelope limits at real time and triggers an alarm if the temperature is outside the set envelope limits.
Data edit keys on the front panel
Allow to edit directly the time and temperature parameters of the heat profile on the graphic display. Those keys are vertically aligned with the profile heating states from Base to Cool2 as displayed on the graphic screen.

IDLE HEAT is for maintaining the thermode at the Idle Temperature when a process is not active. BASE TEMP is for providing a consistent temperature starting point for the process. These functions make it easier to obtain repeatability and to operate reflow soldering which requires more precise control.
Auto-switch of voltage
Automatically changes output voltage in accordance with each setup schedule.
Schedule name registration
Possible to name each schedule with combinations of alphabets and numbers. Helps to distinguish each schedule.
A variety of thermode lineups
Thermodes which meet customers’ requirements can be offered. Please consult for a design of it.
