How much does the Arclight Dynamics Arc Pro Ultra V3 4x8 cost?
Price estimate
We do not have a price for the Arclight Dynamics Arc Pro Ultra V3 4x8 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
Full 4 x 8 sheets load directly onto the Arclight Dynamics Arc Pro Ultra V3 4x8, whose cutting envelope is 54 x 109 in with 9 in of Z. It is the Arc Pro platform running Arclight's own Arc CNC software. The envelope is longer than the sheet by about a foot, which leaves room to clamp, to start off the edge, or to cut a remnant beside it.
Motion on the Arc Pro Ultra V3 comes from NEMA 34 stepper motors working through planetary gear boxes, on a dual-drive gantry with machined aluminum risers. The guides are Hiwin 20 mm precision linear rails with dual seals and scrapers, and the Z axis is a ball screw, which keeps backlash out of torch height moves. Positioning accuracy is listed as 0.001 in. The frame is steel and stands on all-in-one leveling rollers, so the table can be rolled into place and then levelled where it sits. Arclight rates it for 1.5 in mild steel.
The base is 61 x 121 in and overall dimensions are listed as 81 x 162 in and 74 in tall. At 1,100 lb the table still moves on its rollers when the pan is empty; filled, the pan holds 109.1 gallons. Sheet handling decides the layout more than the table does, because a 4 x 8 sheet has to come in flat from one side.
Arc CNC software drives the table from an industrial Linux system over Ethernet. An operator can rewind or fast forward along the cut path after a fault, pick up from the start point after a power-down, and run the laser along the path as a dry run before committing a sheet. A plate-skew angle is entered in the software, so a sheet that lands crooked does not have to be moved. Torch height control and dynamic voltage sampling are standard. A plasma cutter is not included in the base table.

Strengths & Limitations
Strengths
- NEMA 34 motors with planetary gear boxes and a ball screw Z axis
- Arc CNC software with cut-path rewind, start point recovery after power-down and auto rip cut
- Leveling rollers are standard, so the table can be moved and levelled without lifting gear
- 54 x 109 in envelope: a full 4 x 8 sheet with margin left over
Limitations
- Rated for 1.5 in mild steel; heavier plate is the job of the Arc Max tables
- The plasma cutter is a separate choice and is not part of the base table
- Overall footprint is listed as 81 x 162 in and 74 in tall, before sheet-loading space

Frequently Asked Questions
01
Yes. The cutting envelope is 54 x 109 in, slightly larger than the sheet in both directions, with 9 in of Z. The table is rated for 1.5 in mild steel.
02
Yes. All-in-one leveling rollers are standard equipment, so the table can be rolled to a new position and levelled there. Check the weight and the base dimensions of the size you are buying against the floor and the doorway first.
03
The base measures 61 x 121 in and overall dimensions are listed as 81 x 162 in and 74 in tall. It weighs 1,100 lb and its water pan holds 109.1 gallons. Allow space on the loading side for a full sheet.
04
The table is rated for 1.5 in thick mild steel. What it actually cuts depends on the plasma cutter paired with it, which is selected separately. The cutting envelope allows 9 in in Z.
