Overview

The Arclight Dynamics Arc Max Unlimited 6x12 is the largest size in its series: a 73 x 149 in cutting envelope with 6.5 in of Z. It is the reinforced Arc Max table built for 3 in plate, with FlashCut CNC as standard. Six feet of width and twelve of length cover oversize plate and long structural parts without re-indexing.

A plate 3 in thick is a load before it is a cut, and the Unlimited is built around that. Legs are gusseted, slats are 4.5 in deep, and Arclight lists 8,978 lb of weight capacity for this size on a reinforced, fully welded frame of 3 x 3 in tubing. The gantry is the low-mass aluminum dual-drive design with 8.5 in of clearance, on Hiwin 20 mm linear guide rails, with NEMA 34 stepper motors rated 940 oz. Positioning accuracy is listed as 0.001 in.

Everything about siting it is large. The water pan holds 420 gallons, the table is listed at 3,500 lb, the base is 82 x 157 in and overall dimensions are 100.5 in L x 167 in W x 60 in H. Plate of this size moves by crane, so the loading side needs hook coverage and the delivery needs a clear, straight path.

FlashCut CNC is standard and handles drawing, nesting and cutting in one program, including true shape nesting across several DXF files and sheets. The table is meant to be paired with a Hypertherm MAXPRO200 or an oxy-fuel torch for heavy plate, and the cutting source is selected separately. Below the 4.5 in slats, the 8 1/2 in deep water pan has an expanded metal barrier for small parts and drains through twin 1.25 in ball valves.
