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.
