selection relates to such factors as the welding area and the material of the 

weldment, and the amplitude of welding head, etc. Generally, too short weld 

time will lead to insufficient weld strength, while too long weld time will exert 

negative effect on the appearance of the weldment. Actual selection shall be 

determined by means of testing. 

In practical application, the influences of the pressure parameters and the 

parameters for weld time on the weldment are a couple of correlative factors. 

Moderately higher pressure will shorten the weld time; vice versa, to achieve 

longer weld time, lower the pressure appropriately.

Parameters for dwell time 

Dwell time refers to the time for cooling and solidifying the weldment at certain 

pressure so as to prevent deformation of the weldment and loosening of the 

welds after completion of welding. Too short dwell time will affect the strength 

of the finished weldment, while too long dwell time will impact the work 

efficiency. Actual selection shall be determined according to the weldment. The 

fusion face of common small weldment will cool down in a short time, with very 

short dwell time. Big weldment or the weldment with high requirements for 

sealing performance or compression resistance will require relatively longer 

dwell time.   

3. Normal operation 

After installing and commissioning the welder, set the option switch at 

automatic gear, and then the welder is ready for normal operation. Put the 

work piece to be welded into the tooling, and press the operation button

 

on 

operation panel with both hands, the welder will fulfill the complete welding 

process automatically. In the event of any accident during the running of the 

welder, press the emergency stop button in the middle of operation panel, the 

welder will stop working immediately, and return to its original status. The 

emergency stop button of some models is self-locking. Therefore, to make the 

welder resume normal working, you have to turn the emergency stop button 

right to eject and reset it.
