How much does the Arclight Dynamics Arc Max Ultra 6x12 cost?
Price estimate
We do not have a price for the Arclight Dynamics Arc Max Ultra 6x12 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Arclight Dynamics Arc Max Ultra 6x12 is the largest size in its series: a 73 x 149 in cutting envelope with 6.5 in of Z. It is the heavy-frame Arc Max table running Arclight CNC software. Six feet of width and twelve of length cover oversize plate and long structural parts without re-indexing.
Weight is deliberate here. A fully welded, unitized frame of 3 x 3 in tubing with a 3/16 in wall carries a light aluminum gantry on Hiwin 20 mm linear guide rails, driven on both sides. Gantry clearance is 8.5 in. Arclight rates the table for 2 in mild steel and lists 0.001 in positioning accuracy. Plate slides on over rollers built into the frame, level with the slats, and the table ships fully assembled.
Everything about siting it is large. The water pan holds 420 gallons, the table is listed at 3,000 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.
The water table is unusually deep: an 8 1/2 in pan in 12g steel, with an expanded metal barrier partway down so small parts do not sink to the bottom, and twin 1.25 in ball valve drains. Arclight says it captures 90% of smoke and dust. Control is by Arclight CNC software on industrial Linux over Ethernet, with torch height control, dynamic voltage sampling, cut-path rewind, start point recovery and auto rip cut. A plasma cutter is added when the table is configured.

Frequently Asked Questions
01
73 x 149 in, with 6.5 in of Z. It is the largest size Arclight lists for this series and takes 6 x 12 plate, which slides on over rollers built into the frame.
02
Arclight lists the table as shipping fully assembled. The frame is one welded unit, so plan the delivery route and unloading equipment around the overall dimensions and weight of the size ordered.
03
Floor for a base of 82 x 157 in and overall dimensions of 100.5 in L x 167 in W x 60 in H, a floor that carries 3,000 lb plus 420 gallons of water and the plate, 110 V at 15 to 20 A for the table, and lifting gear for the material.
04
It is a fully welded, unitized frame of 3 x 3 in steel tubing with a 3/16 in wall, powder coated. The gantry is low-mass aluminum with 8.5 in of clearance, on Hiwin 20 mm precision linear guide rails. The table is rated for 2 in mild steel.
