WeldPro 360 LRW 18P Mig Welding Arms

The WELDPRO 360-LRW-18P Mig Welding Arm is mounted to your existing building support column, freestanding column, or the optional mobile base and column assembly.

The WELDPRO 360-LRW-18P Design

The design is built around placing the wire feeder at the end of the welding arm. As is common to all WeldPro 360-LRW models, mounting the wire feeder within easy reach of the operator saves time by eliminating the need to walk back and forth to the power supply to make weld setting changes and adjustments.

The WELDPRO 360-LRW-18P comes with two boom arms, a primary arm, and a secondary arm.  The primary arm is attached to the boom arm pivot assembly and has a maximum of 192° of semi-circle rotation.  A double-articulated joint arrangement connects the primary and secondary arms.  The double-articulated joint assembly allows the secondary arm to rotate a full 360° off of the primary arm, providing a complete coverage zone of 56' in diameter with a 15' weld gun.  

Boom control requires only 90 PSI of compressed air and 120V electricity for locking and unlocking the primary arm for rotation.

The WELDPRO 360-LRW is designed so that the customer can install their wire feeder and power supply of choice. 

Keeping with the WeldPro 360 LRW tubular arm design, all hoses and cables for gas, air, power cables, and wire feeder are contained within the arms - making for a safe, clean, and organized installation.
