Weld Settings Screen
Operation
The Weld Settings Screen is used to set the desired
voltage and duration of the weld discharge. The Pico
can be congured to release two independently set
pulses of weld energy with customizable pre-weld delay
and delay between pulses.
Pulse settings dictate the amount of energy that will
be released during each weld. As voltage and length
increase, weld heat will increase.

A graph (A) at the top of the Weld Control Screen dis-
plays a visual representation of the expected waveform
based on the weld settings and parameters you choose
here. Weld voltage is displayed on the Y axis and weld
discharge length (time) is displayed on the X axis.

A total of two weld pulses can be enabled/disabled. Us-
ing multiple pulses can increase weld quality. With both
pulses enabled, the Pico will discharge two separate
times with each weld trigger/initiation. The rst pulse is
useful to remove surface inconsistencies and contami-
nants which helps to displace oils, break through oxide
layers, and seat the welding electrodes. The second
pulse is used to fuse the metals.
To set pulse parameters, rst toggle the button (B) to
ON to enable the pulse, or OFF to disable the pulse for
Pulse 1 or Pulse 2. If both pulses are disabled, no weld
will occur and an alert will display if a weld is triggered.

The voltage of each pulse can be adjusted from 0.1 V to
5 V. To adjust voltage, touch the Voltage box (C) of the
desired pulse. A pop-up box will appear. Use the slider
bar or the number pad to set the displacement limit; or
incrementally adjust the value using the arrow buttons.
Press the Close Button to enter the limit.
