Part I General Description
The Bernard PipeWorx MIG Gun is designed primarily for process-
ing mild steel electrode under GMAW (Gas Metal Arc Welding), MIG
(Metal Inert Gas), MAG (Metal Active Gas), FCAW (Flux Cored Arc
Welding), and MOG (Metal without Gas).
The PipeWorx MIG Gun provides rapid neck interchangeability, typi-
cally during production processes. Neck may also be positioned on
line within a 360 degree rotation. This position allows for movements
between standard horizontal welding, overhead, and hard-to-reach
side angles. The neck includes an optional jump liner system that
effectively reduces costs associated with one-piece liner systems.
Bernard is concerned about your higher productivity.
The PipeWorx MIG Gun meets or exceeds NEMA (National Electrical
Manufacturer’s Association) EW3 requirements for guns used in a
wide variety of applications including aluminum, silicone bronze, and
hard facing alloys to name a few. With Bernard’s flexibility, many ap-
plications can be accommodated with field installed options increasing
performance and maneuverability.
1. Your gun has been shipped with a specific feeder connector,
neck, and sized for electrode as per the part number indi-
cated on its package. Please inspect the received gun against
this part number for accuracy.
2. Turn off power prior to any installation.
3. Fully extend gun and cable. Press liner fully into power pin.
4. Safely expose approximately 2” (51 mm) of electrode
beyond feeder or adaptor block.
5.
Power Pin
Connect the power pin of the direct plug gun by sliding
the electrode into the liner and the power fitting into the
drive housing of the feeder. Fully seat the unit in position
and tighten into place as designated in the manufacturer’s
instructions. On initial installations, a thin film of silicone
lubricant will aid installation and prevent o-ring damage.
Attach control lead wires to the appropriate plug, terminals,
or lead kit. Plug or wire into the control circuit of the feeder
as designated in manufacturer’s instructions.
If a gas hose is provided, connect to the feeder’s solenoid
circuit to deliver shielding gas to the arc. If no gas hose is
provided, gas is delivered through the power pin. Refer to
the manufacturer’s instructions for proper gas connection at
the feeder block or solenoid.
6. Remove nozzle from head assembly.
7. Pull contact tip from head/gas diffuser. An unobstructed
electrode path has now been established.
8. Safely feed electrode through the gun and approximately 1”
(25 mm) beyond head/gas diffuser.
9. Reinstall the contact tip over the electrode and lock into
position by reinstalling the nozzle.
Welding current and duty cycle
shall not exceed published
specification of this product. If such
conditions exist, product life and
performance will be reduced.
