No argon mix, and three empties behind the building
A welder goes to change a cylinder of argon and CO2 mix and there is no full one. The gas supplier can deliver tomorrow. Behind the building there are three empties that should have been swapped last week, and a cylinder of pure argon that nobody has used for months, still being rented.
In the same week, the laser runs out of the nozzles it uses for thin stainless, and the MIG wire in one size is down to its last spool.
Why consumables are always a surprise
Gas and consumables are small, frequent purchases handled by whoever notices. Cylinders are rented and move around, so the supplier's rental list and what is really on site drift apart. Nobody links what is used to the work that used it.
- Cylinders are not tracked by serial or barcode on site.
- Empties are not returned promptly.
- The rental invoice is paid without checking.
- Wire, tips, shrouds, nozzles and lenses have no minimum levels.
- Usage is not linked to jobs or machines.
What it costs
Welding bays and lasers stopped for want of a cylinder or nozzle. Emergency deliveries. Rental paid on cylinders you do not use or no longer have. And no idea what gas and consumables cost per job, which makes welding and laser rates harder to set.
The cylinder and consumable tracking we build
- Each cylinder is scanned in on delivery using the supplier's barcode or a label you add, with gas type and size.
- Cylinders are scanned when connected at a bay, when empty, and when collected, so their status and location are known.
- The on site list is compared monthly with the supplier's rental statement, highlighting cylinders you are charged for but do not hold, and ones held but rarely used.
- Welding wire, tips, shrouds, laser nozzles, lenses and other consumables have stock levels and minimums, and are booked out by scan.
- Reorder prompts are based on actual use, and orders are grouped by supplier for approval.
- Usage can be linked to machines and, where it makes sense, to jobs, so consumable costs can be included in job costs and rates.
| Tracked | Why |
|---|---|
| Full, connected and empty cylinders | No bay without gas |
| Cylinders against the rental statement | Stop paying for ones you do not have |
| Wire, tips and shrouds | Reorder before the last spool |
| Laser nozzles and lenses | Keep the right sizes for each material |
| Usage by machine or job | Consumables in your rates |
What changes
Full cylinders are available when needed, because low stock prompts an order in time. Empties go back on the next delivery. Rental charges match what you hold. Laser and welding consumables are reordered from real use. And the cost of gas and consumables is visible, which helps when setting welding rates or deciding whether bulk gas makes sense.
It also saves the welders time. They know where the next full cylinder is, and the right wire is in stock.
The laser team gets the same benefit with nozzles, ceramics and protective windows. Each has a minimum by size and type, so the nozzle for thin stainless is not the one that has quietly run out, and the lens that should last a set number of hours is replaced on a known basis rather than when the cut quality drops.
Is gas and consumable stock catching you out?
- Bays stop waiting for a cylinder.
- Empties sit on site for weeks.
- Nobody checks the cylinder rental invoice.
- Laser nozzles or lenses run out unexpectedly.
- Consumable costs are not in your job costs.
