LJ’s Column & Boom Manipulators are used in applications of automated welding, where precision and efficiency are necessary. They provide weld boom stiffness, welding head stability, operator controls, and ease of use as key driving factors


LJ's 4' x 4' GMAW Column & Boom Manipulator Rental easily integrates with PEMA roller-beds and positioners. Operators also use them for welding longitudinal and circumferential seams. Our MNC4-100 rental has a loading capacity of 250 lb and boom/column stroke of 48". A wide selection of accessories and options is available depending on the customer's request and need. As far as the welding source options are concerned, we offer submerged arc (SAW), MIG, or a solution to the customer’s specification. We also offer control upgrades including full integration to LJ welding positioners or turning rolls through HMI touchscreens and master PLC.


LJ’s 4' x 4' GMAW Column & Boom Manipulator Rentals allow maximum flexibility to welding head manipulation which results in a higher quality of welds. Another benefit is the low skill cap for operators due to automated processes. Generally, our welding manipulators are indispensable for applications that involve pipes and vessels. They are ideal for hard automation welding solutions and they offer modular construction that ensures 360-degrees radial accessibility to welding heads, covering vast areas in the shop.
