ESAB PB-3 Plumbing Box
The ESAB PB-3 Plumbing Box is designed to work with the robotic analog interface to regulate gas, detect torch coolant flow, and incorporate a gas flow/pressure sensor.
Key Features:
- Controls gas on/off with 110VAC activation.
- Detects torch coolant flow with a flow switch set for activation at 0.25 GPM.
- Provides safety ground connection.
- Allows for the installation of a gas flow/pressure sensor for added monitoring.

P/N 34749
GENERAL
Plumbing Box Model PB-3 is designed for use with the
robotic analog interface to control gas on/off and to de-
tect torch coolant flow. Gas control is activated from the
analog interface switching 110 vac to pins A and B of the
plumbing box receptacle. Water flow is sensed via a flow
switch on pins E and F of the plumbing box receptacle.
Activation of the 24 vdc circuit is set for .25 GPM. Safety
ground for the plumbing is connected to pin D. No con-
nection is made on pin C. Provisions have been made
for the user to install a gas flow/pressure sensor if de-
sired (See schematic diagram). Due to the inherent sen-
sitivity problems with such devices, it is up to the user to
determine and install a suitable device for his particular
application.
INSTALLATION
1. Secure the plumbing box in a suitable location us-
ing the mounting brackets provided. All plumbing box
interconnections are clearly marked for ease of as-
sembly. See FIG. 1.
Be sure this information reaches the operator.
You can get extra copies through your supplier.

2. Connect the PB-3 plumbing box to the analog inter-
face by means of the 6 pin control cable assembly.
The control cable is installed between the analog
interface receptacle J4 and the plumbing box re-
ceptacle marked Weld Interface. Two control cable
lengths are available;
4.5 ft. Part Number 34199
25 ft. Part Number 34845
3. Connect the gas supply from a flowmeter/regulator
to the gas in fitting on the plumbing box. The sys-
tem is designed to deliver adequate flow for all typi-
cal welding applications. Maximum recommended
delivery pressure is 50 psi.
4. Connect the welding torch gas “IN” hose to the gas
“OUT” fitting on the plumbing box.
5. Connect the coolant supply line to the water “IN”
connection in the plumbing box.
6. Connect the welding torch coolant (water) “IN” hose
to the water “OUT” connection on the plumbing box.
