Picó
Secondary Trigger
Use the Secondary Trigger Port (G) to connect a foot
pedal, or other switch, to initiate a weld.
Positive and Negative Weld Terminals
Use the Positive and Negative Weld Terminals (H) to
connect the weld cables from a weld head or hand at-
tachment to the Pico to deliver weld energy. See Figure
10.1. Make sure weld cable resistance is greater than or
equal to 1 milliohm (1mΩ) of resistance.
Cooling Fans
The Pico’s cooling fans (I) are internally powered and
controlled. Make sure the fans are free from obstruction
and have at least two inches of free space behind the
welder for optimum airflow.
Fuse
For safety, the Pico uses a 5mm x 20mm 15amp fuse (J)
rated for up to 250VAC.
Power Inlet
The Pico Power Inlet (K) requires an IEC 320 C13 power
cord and can accept 90-250VAC, 50-60Hz.
Exploring the Side Panel
The welder features a USB port on the left side, near
the front. See (L) in Figure. 10.2. The USB port can be
used for three purposes:
1. Update the firmware and software of the welder
(see Chapter 3 for software update instruc-
tions).
2. Export and import saved schedules, welder
settings, and historical weld data (see the
section on Import/Export tab on page 28).
3. Connect a USB mouse and use the mouse to
navigate the interface.
