Ultrasonic welder UWM300

Ultrasonic technologies are set out because of their benefits in different branch industry of series production, short-run production or research work. It is the same for ultrasonic welding. 

Specific merits of the plastic welding of , non-woven textiles, artificial leather etc. are:

  • care of environment - plastic jointing without sizing materials or chemicals
  • small power spending - ultrasonic machine is not heating during welding
  • cleanness, work without mechanical or chemical rubbish
  • high level of repeatability and the same quality of weld
  • short time of his own welding process
  • small severity of space and small weight of the technological machine 



Ultrasonic set for manual welding (further on only “welding set”) is designed for direct welding of plastic materials such as  plastic foils, non woven textiles, etc. It is possible to use it for joining other materials by suitable plastic rivets. 


Welding parameters could be set with buttons in front of

  • Ultrasonic intensity “Intensity” - determines the intensity of ulrasound as a percentage
  • Welding time “WeldTime” - determines time of cooling weld
  • Hold time “HoldTime” - determines time of cooling weld 

Timer activation, notice “Timer”
Buzzer activation, notice on display “Beep”


The data displayed on the display:

READY - the welder is ready for welding
Run - welding with ultrasonic power
HOLD - warning, the display shows number of warning
Err - error

The second line shows operating parameters:

 int1 - ultrasonic intensity in %
 T1 - welding time in seconds
 Th - cooling time in seconds
 F1 - operating frequency in Hz
 Tg - generator heat in °C
