Pulse 1 voltage is generally less than Pulse 2 voltage. To help determine ideal Pulse 1 settings, turn o Pulse 2
and do a series of test welds starting at a low voltage setting. Increase the voltage about 3% each test until the
welded parts barely stick together. If using thermocompression electrodes, check to see that the voltage was
high enough to melt the coating of the magnet wire.
Pulse 2 Voltage will usually be set higher than Pulse 1 Voltage. Increase the Voltage incrementally until desired
weld strength is achieved.
Note: If using thermocompression electrodes, always start with a low setting and work up until desired results
are achieved. Setting the voltages too high at rst can damage the tip.
The duration of each pulse can be adjusted from 0 to 500ms. Press the Length “SET” button of the desired
pulse duration (D) and use the keypad to enter a value; or incrementally adjust the value using the arrow buttons.
Setting the length of the weld discharge can help ne tune weld results, especially when using thermocompres-
sion electrodes.
It is recommended to start with shorter lengths and work up with each weld test until desired results are
achieved.
A delay can be set to control the amount of time between the end of Pulse 1 and the beginning of Pulse 2. The
duration of a delay can be adjusted from 0 to 1000 ms. Delays are represented on the waveform display as a
gap between the peaks. The delay will only be available when both pulses are enabled.
To set a delay, press the Delay box (C). A pop-up box will appear. Use the slider bar or the number pad to set the
delay; or incrementally adjust the value using the arrow buttons. Press the Close Button to enter the delay.
ADDITIONAL WELD ENERGY NOTES
For new applications, a test weld should be performed, and the resulting weld should be evaluated for strength.
A pull tester can be utilized for most accurate strength results, but visual examination can be useful as well.
The Pico welder allows users to ne tune the energy and length settings to dial in the ideal weld strength.
