WeldPro 360 LRW-18P MIG Welding Boom Arm








The WeldPro 360 LRW-18P boom arm delivers the same double-articulated performance enhancing capabilities as the revolutionary WP360-LRW 18, but with a simplified design. The 18P differentiates itself, by eliminating the vertical motion of the secondary arm. If you don’t need to weld at extended heights—more than 10’ above the floor—then the 18P is a great choice.
The standard mounting height for the 18P arm is 10’ and the arm incorporates a unique, swiveling pendant—at the end of the secondary arm—which mounts the wire feeder a comfortable 60” above the floor for easy access to welding controls and boom operation. Don’t be fooled into thinking the pendant hinders the boom operation, in almost every case the double-articulation capabilities of this unique arm, allow you to fold the secondary arm back alongside of the primary arm (effectively shortening the arm to 10’) and quickly maneuver around obstructions.

The primary arm is 10’ long and the secondary arm is 8’ long. The primary arm rotates 192° around the main pivot point, providing complete welding coverage within a 56’ diameter semi-circular welding zone when using a 15’ MIG welding gun. The secondary arm rotates a full 360 degrees about the end of the primary arm and eliminates all unreachable dead zones, common to single-articulated, straight-arm booms.
Create clean and organized welding cells by routing all hoses and cables within the interior of the LRW-18P’s welding arm—no more unsightly cables and hoses hanging from the arm or laying on the shop floor creating a safety hazard. The primary arm incorporates an electrically controlled, positive stop rotation brake and the secondary arm has a no touch friction brake to hold the entire arm in position. Ball bearing pivot points make repositioning the arm an almost effortless task, moving from position to position in mere seconds.

With the ability to mount wire feeders from any supplier of choice, you can place the necessary welding controls right where the operator is working, no more wasted time going back and forth to the welding machine to make adjustments to the weld process.
When installing the WP360-LRW 18P arm, there are five basic options available from which to choose, giving you the ability to tailor your installation for maximum return on investment. The options range from a wide-open, do-it-yourself approach, to a fully engineered and ready to install solution, using readily available, WeldPro 360 designed and engineered components.
Install a WeldPro 360-LRW 18P MIG welding boom arm in your shop and like hundreds of other shops, you will see your productivity soar!
