Gas delivery that keeps the cut steady
An assist gas pack forms the supply side of the cutting process, feeding the line from the source to the laser head with control and consistency. In tube and profile work, stable pressure helps the machine clear molten metal, shape the kerf properly and hold edge quality through long runs and short nests.
The pack is built for fibre laser applications where the cutting head needs predictable flow during piercing, cutting and corner changes. On thicker mild steel the demand is higher, while stainless and aluminium work usually calls for cleaner gas handling and tighter pressure control.
- Suitable for oxygen, nitrogen or air delivery setups
- Supports repeatable pressure at the machine inlet
- Used with tube chucks, profile beds and bevel heads
- Helps reduce rough edges, slag and inconsistent pierce marks
Pack sizes and control options
Assist gas packs are supplied in layouts that suit single machines, shared workshop lines and heavier production cells. A compact package works well for one tube cutter with one gas type, while larger installations often need separate regulation paths for different materials and cutting recipes.
Control options can include pressure regulation, filtration, isolation valves, gauges and manifold sections arranged for the way the machine is used. Where the work mix changes often, operators need clear control at the machine end, not just at the bulk source.
- Single machine packages for job shops and smaller fabricators
- Multi-line packages for shared cutting areas
- Pressure regulation sets for oxygen and nitrogen work
- Filtration and moisture control for cleaner delivery
- Manifolds for switching between cutting gases
Where this package suits the cut list
This package suits fabricators cutting structural tube, furniture tube, frame parts, agricultural steel, trailer parts and general plate and profile work. Wadeville and Germiston shops often need a setup that can handle mixed orders, from short repair runs to heavier batch work, without constant manual adjustment.
It also suits plants running tube and profile cutting alongside downstream welding or bending, where the cut edge has to stay clean enough for fit-up. On angular and channel sections, good gas delivery helps keep the profile edge consistent through corners, not only on straight sections.
- Round, square and rectangular tube cutting
- Angle, channel and open profile processing
- Mixed-material production with changing cut settings
- Workshops serving local fabrication and site steel jobs
Installation, fitting and machine interface
Fitting the assist gas pack calls for proper connection to the source, clean pipework or hose runs, and pressure settings matched to the machine and material schedule. The installation team checks flow direction, regulator placement, leak points and access for service before the system is handed into daily use.
On a laser tube line the gas package must sit neatly with the cutting machine, the nesting software output and the operator workflow. If the machine has a bevel head, the gas delivery has to stay stable through angle changes and pierce cycles so that the cut quality remains controlled.
- Connection to workshop gas supply or cylinder manifold
- Regulator and gauge layout matched to cutting needs
- Leak testing on lines, joints and valves
- Positioning for easy operator access and servicing
- Integration with the machine’s gas control inputs
Care that keeps flow and pressure consistent
A gas pack works best when filters are checked, moisture is kept out and regulators stay within their normal operating range. Dust, oil carry-over and water in the line can affect valve life and make pressure drift more likely during the day.
Operators should watch gauges, listen for leaks and keep the area around the pack clear so fittings can be inspected without delay. Preventive maintenance often includes filter replacement, seal checks, regulator inspection and verification of line pressure against the cutting program.
- Check moisture traps and filters at planned service intervals
- Check hoses, unions and valve bodies for leaks
- Keep pressure settings matched to the job card
- Watch for unstable readings during pierce cycles
Details to confirm before ordering
The right pack depends on the machine size, the gas type in use and the volume of cutting planned for the workshop. A tube cutter that runs light aluminium work all week will not need the same layout as a production line cutting heavy mild steel sections and open profiles.
It helps to confirm the cutting head type, the number of lines needed and whether the setup must support oxygen, nitrogen or shop air. For larger jobs, confirm the source pressure, available space at the machine and whether the pack will sit on a wall, skid or frame beside the cutter.
- Machine model and cutting head arrangement
- Gas type, source pressure and line capacity
- Number of cutting stations or heads
- Expected material range and wall thickness
- Available mounting space and pipe run length
