Part I General Description
The IronPro™ 450 Self-Shielded MIG Gun is designed primarily for
processing mild steel electrode under FCAW (Flux Cored Arc
Welding).
The IronPro™ 450 Self-Shielded MIG Gun provides rapid neck
interchangeability, typically 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 IronPro™ 450 Self-Shielded MIG Gun meets or exceeds NEMA
(National Electrical Manufacturer’s Association) EW3 requirements.
1. Your gun has been shipped with a specific feeder connector,
neck, and sized for electrode as per the part number
indicated 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.
6. Pull contact tip from neck tip adapter. An unobstructed electrode path has
now been established.
7. Safely feed electrode through the gun and approximately 1” (25 mm)
beyond head.
8. Slide contact tip over electrode into tip adapter on the neck by hand and
tighten with non-marring pliers. Torque to 30 in-lbs (3.5 Nm).
NOTE: AccuLock™ tip tool part # T-ALTOOL is recommended.
Welding current and duty cycle
shall not exceed published
specication of this product. If such
conditions exist, product life and
performance will be reduced.
