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.

Part II Installation

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.

Commercial Warranty

Product is warranted to be free from defects in material and

workmanship for 1 year after the sale by an authorized Buyer. Straight

handles, straight handle switches and straight rear strain reliefs are

covered by a lifetime warranty.

Bernard reserves the right to repair, replace or refund the purchase

price of non-conforming product. Product found not defective will be

returned to the Buyer after notification by Customer Service.

Bernard makes no other warranty of any kind, expressed or implied,

including, but not limited to the warranties of merchantability or fitness

for any purpose. Bernard shall not be liable under any circumstances

to Buyer, or to any person who shall purchase from Buyer, for

damages of any kind. Including, but not limited to any, direct, indirect

incidental or consequential damages or loss of production or loss of

profits resulting from any cause whatsoever, including, but not limited

to, any delay, act, error or omission of Bernard.

Genuine Bernard parts must be used for safety and performance

reasons or the warranty becomes invalid. Warranty shall not apply

if accident, abuse, or misuse damages a product, or if a product is

modified in any way except by authorized Bernard personnel.

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.

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.
