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

specication of this product. If such

conditions exist, product life and

performance will be reduced.

Part II Installation

1. Tip insulation could be unthreaded slightly to extend the life

the of part.

Cable:

1. Periodically check torques of neck and end fittings. Loose

fittings can cause overheating and premature failure of the

gun.

2. Sharp bends and loops in the cable should be avoided. Often

the best solution is to suspend the wire feeder from a boom

or trolley, thus eliminating a large number of bends and

keeping the cable clear of hot weldments.

3. Do not immerse liner into solvents for cleaning; the liner may

be periodically blown out with compressed air.

4. Avoid rough surfaces and sharp edges that can cause tears

and nicks in cable jacket which can cause premature failure.

5. Periodically check all cables and ground connections.

6. Use anti-seize on all threaded connections.

Part III Helpful Operating Tips

Tip Insulation:

Feeder:

1. Check drive rolls for wear; be sure drive rolls and guide

tubes are clean and free of debris. Do not overtighten drive rolls;

set as per manufacturer’s specifications.

2. Use clean, non-corroded electrode.

3. When installing or replacing electrode, you may: remove

burrs from end of electrode, remove head/gas diffuser and

contact tip, and/or straighten the first few inches of elec-

trode.

End User Stocking Recommendations:

Contact Tips .............................. 30 for every 1 gun in service

Triggers ..................................... 1 for every 10 guns in service

Necks ........................................ 1 for every 10 guns in service

Handle Kits ................................ 1 for every 20 guns in service

Strain Relief Kits ....................... 1 for every 20 guns in service

Power Pin Kits .......................... Order as Necessary

These stocking recommendations are only initial guidelines based on

an 80 hour work period. You should work closely with your distributor

to tailor a stocking program that suits your specific needs. Results will

vary.

Disconnect gun from equipment, allow to cool, and remove electrode from liner before servicing.

Part IV Maintenance and Repair

See page 17 for parts list

CONVENTIONAL CABLE LINER

REMOVAL

1. Remove neck, heat shield and heat shield nut and lay cable straight.

2. Remove rear guide cap, then using a 10 mm wrench, turn liner counter-clockwise until it is free from the power pin.

3. Remove liner from gun assembly.

SERVICE

1. Inspect for excessive wear and debris on the inside diameter. Do not dip liner in solvents for cleaning. Liner may be

periodically blown out with shop air. Replace with new liner when excessive wear or debris produces poor electrode feed.

INSTALLATION

1. With cable laying straight, insert new liner into power pin and feed through gun using short strokes to prevent kinking. Twist

liner clockwise if necessary.

2. Use a 10 mm wrench to turn liner lock clockwise to tighten into power pin, then replace guide cap.

3. Trim liner flush with front adapter block (as shown in the above figure).

4. Then reassemble neck and heat shield.

WARNING

Part IV Maintenance and Repair (cont.)

2. Before installing, inspect neck and adapter block of the front

gun handle for debris, clean if necessary. Then, take the tapered

end of the neck and insert into adapter block, making sure the

cable liner is inserted into jump liner.

3. Install neck in reverse order of removal, adjust neck by twisting

into place, torque to 38in-lbs.

Jump Liner

1.Remove used jump liner from the back end of neck.

Inspect for excessive wear and debris on the inside diameter.

Do not dip jump liner in solvents for cleaning. Jump liners may

be periodically blown out with shop air. Replace with new jump

liner when excessive wear or debris produces poor electrode

feed.

Insert jump liner making sure the liner stop is fully seated

at the back of the neck. For new jump liner replacement,

measure the jump liner from rear of liner lock to tip of the

liner. For 12" long necks (1370270) measure and trim to

10-7/8". For 7" short necks (1370271) measure and trim to

5-7/8".
