The WELDPRO 360-LRW Mig Welding Arm is mountable to your existing building wall, support columns, or the optional mobile base and column assembly.

There are 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.

Unique to this design is its ability to raise and lower the wire feeder up to 5′-6″, providing 20′ of reach with a standard mounting height.  Arm rotation for the primary arm and raise/lower functions of the secondary arm are controlled with a wireless remote that hangs on the operators belt.  Boom control requires only 90 PSI of compressed air and a 120V electricity.

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

The light weight arm weighs at just over 300 pounds.  The tubular arm design, contains all hoses and cables for gas, air, power cables and wire feeder within the arms – making for a neat and tidy installation.
