Inventory Replenishment / Welding Shops

Arda's inventory replenishment software for welding shops

The cylinders that stop your arc are leased, so they never enter your ERP as inventory at all. The tips, cups and tungsten that stop it just as often are too cheap for anyone to log. Arda puts a scannable card on both, and on the filler metal and weld-on parts that are on the print, so one scan fires the reorder and the arc keeps burning.

Your first 10 cards are free. Works alongside your ERP, no rip and replace.

Trusted by manufacturers including Rossmonster, Austere, and Fat Fender.

Never stock out on anything your shop holds

A stockout is a reorder that fired too late, or never fired at all. Count-based systems leave that trigger to a person, and people are busy. Arda makes the trigger physical: the card on the bin is the reorder, sized to your supplier's lead time, so replenishment starts the moment stock runs low and the shelf refills before the second bin runs dry. That works the same on a cylinder of shielding gas, a bin of contact tips, or a spool of MIG wire.

The trigger can't be skipped

Scanning the empty bin is the fastest way to get more, so the reorder fires on its own, every time.

The buffer is sized, not guessed

Reorder point and safety stock are set to your real burn rate and lead time, so the second bin always covers the wait.

It holds as demand shifts

When a job changes what you burn, you resize the card once. Nobody recalculates a min/max by hand.

The shelf did not fail. The signal did.

Nothing plans your gas or your tips, for two opposite reasons

A welding shop's shelf is bimodal. At one end sits a cylinder you do not own, do not receive and cannot read from ten feet away. At the other sits a box of 0.035 contact tips too cheap for anyone to log. Both of them stop the arc, and the arc is the whole product.

01

Your cylinder rack looks full right up until it isn't

Empties and fulls chain up in the same rack against the same wall, and from ten feet they are identical. So the shortage gets found by a welder mid-bead, when the shielding cuts out and the last four inches go porous. By then the gas house has already run its route.

02

Too big to log, too cheap to bother

A leased cylinder never enters your ERP as inventory because you do not own it. A box of 0.035 contact tips is too cheap for anyone to log. The two items most likely to stop the arc are the two nothing is watching, for opposite reasons.

03

Arc-off time is already eating the day

Industry-average operating factor is about 20 percent, roughly 12 minutes of arc per labour hour. Five minutes hunting a full bottle or a fresh box of tips is not an inconvenience. It is the product.

How does inventory replenishment work in a welding shop using Arda?

Arda's inventory replenishment software for welding shops puts a scannable card on the cylinder rack and on every bin at the bench, so the scan fires the reorder on its own. No purchase order to type, no ERP rollout, and nothing new for the welder to do beyond the thing that already gets them more gas. It is the same card-and-scan loop Arda runs across every trade, set out in full on the inventory replenishment software hub.

Built for both ends of a welding shop's shelf

The loudest pain is off-BOM: the gas and the gun parts that never reach a bill of materials, so nothing is watching them. The same card works on the filler metal, weld studs and backing rings that are on the print. One motion for everything the shop holds.

1

Scan the card when the rack or the bin runs low

Every stocked item gets a durable card with a QR code, from the cylinder rack to a bin of contact tips to a spool of ER70S-6. A welder scans it with the phone already in their pocket. No extra hardware, no login friction.

2

The order fires automatically

The scan hits Arda's backend, which places the reorder at the right quantity from the right supplier. No purchase order to type.

3

See every card, pulled to restocked

Purchasing and the owner watch which cards are pulled, on order, or restocked across parts and locations, without walking the floor.

Your gas house already owns the cylinders, bills the rental, keeps its own cylinder balances and hydrotest records, and drives a fixed route. That is a vendor-managed arrangement in everything but the name, and the cards run inside it rather than beside it: the supplier keeps the asset records, Arda fires the request from the rack.

Each card encodes a proven loop sized to your real consumption: reorder point, the two-bin system, min/max levels, and safety stock. The math lives on the card, not in someone's head.

Built for the shop floor, not the back office

Count-everything tools fail because they add a task. Arda removes one. That is what holds compliance past week one.

No counting, ever

The card is the replenishment signal, on every item you stock. Nobody tallies stock or runs a cycle count to make the numbers real.

Adoption that holds

The simplest way to do the job is to scan the card, so compliance sticks where badge-in ERP screens lose the floor on day one.

One scan, any phone

No scanner gun, no new login, no training day. A welder scans with the phone already in their pocket, so nothing new stands between them and the reorder.

The signal lives on the floor

Reorder point, min/max, and safety stock are baked into the card at the point of use, not buried in a back-office sheet that drifts the moment demand shifts.

What each role gets

Shop-floor welder

One scan when a bin runs low, and the refill is already moving. Same motion for every item on the floor. No software to learn.

  • No hunting down whoever does the ordering. Scan the empty bin and get back to the machine.
  • No dead stop mid-weld because the contact tip bin is empty and nobody caught it.
  • Nothing new to learn. If you can scan a card, you already know the whole system.

Purchasing / office manager

Orders fire at the right quantity with no stack of manual POs, and every card's status is in one place.

  • No typing purchase orders by hand or chasing the floor to find out what got used.
  • No surprise "we're out" that turns into a premium rush order.
  • Pulled, on order, restocked: every card's status in one view, so nothing inbound is a mystery.

Owner / lead

Hands off reordering for good and gets the hours back for quoting, with real consumption data across the whole shelf instead of gut feel.

  • Reordering stops eating the hours you would rather spend quoting and winning work.
  • No cheap consumable, and no missing spool of wire, stalling an expensive machine because a reorder slipped.
  • Real consumption trends to quote materials from, instead of gut feel.

Frequently asked questions

How do you keep from running out of shielding gas in the middle of a job?
Stop making it a walk-over-and-look problem. Put a two-bottle rule on each active gas type and a scannable card on the rack, so the moment a welder pulls the last full cylinder onto the bench they scan the card and the replacement is already ordered. A 125 to 150 cf cylinder at a normal 12 to 15 L/min flow gives roughly 10 to 12 hours of arc, which at a busy bench is two or three shifts, not a month. The card is sized against your gas house's delivery route, so the refill lands while there is still gas at the bench. More on the two-bin system.
How many spare gas cylinders should a welding shop keep on hand?
One full spare per active gas type per bench, not one spare for the building. The number is set by your supplier's route rather than by your consumption. Most welding shops buy from a local gas house running a fixed two-day-a-week delivery, so an empty on Wednesday afternoon is a cold bench until Friday unless something already fired on Tuesday. Size the card to cover the gap between routes plus a shift of cushion, and the rack carries the answer instead of a person carrying it. Run C25, pure argon and a tri-mix and that is three cards, not one.
Should we lease or own our gas cylinders, and does it change how we replenish?
Most shops lease, and it changes where the signal has to live rather than whether you need one. A leased cylinder belongs to the gas house, so it never enters your ERP as inventory, and the rental or demurrage clock runs whether the bottle is full or empty. Owning kills the rental line but hands you the capital and the hydrotest dates, which is why leasing stays normal well past the point most shops expect. Either way the replenishment problem is identical, because ownership decides who holds the asset and the card decides when the refill leaves the gas house. Arda does not replace your supplier's cylinder balances or its rental billing. It runs the pull signal on your side of the fence: what to send, how much, and when, fired from the rack instead of remembered by a person, on the same route they already drive.
How do you replenish contact tips, nozzles and tungsten at the bench?
Put a second bin behind the first and card the empty one. The welder takes the last handful of 0.035 tips, scans the card, pulls the second bin forward, and the reorder is already moving before anyone has to ask for it. The same setup holds for nozzles, diffusers, liners, collets, gas lenses, alumina cups and each tungsten diameter, which is where most shops get caught: they hold four sizes of everything and run dry on exactly one. The empty bin is the signal, and the quantity is already on the card.
Why do welds go porous halfway through a shift?
Usually consumable wear, not bad gas. A contact tip burned past its bore wanders the arc, a nozzle packed with spatter chokes the shield, and a plugged diffuser starves it, so coverage goes intermittent and the bead goes porous. The fix is a fresh tip and a clean nozzle at the bench, which only happens if there is a fresh one to reach for. Shops that card their gun consumables stop diagnosing a purchasing problem as a gas problem, because the box is never empty when the welder reaches into it.
Does Arda work alongside my ERP?
Yes. Arda runs the replenishment loop for everything you stock and slots in where ERP and MRP fall hardest, on the variable-consumption goods that never make it onto a BOM. Your ERP keeps doing jobs, routing, and costing. It integrates with QuickBooks, NetSuite, Odoo, Xero, Shopify, Stripe, Airtable, Make, and Zapier, plus a REST API, so there is no rip and replace.
How much does Arda cost, and is there a free trial?
Arda prices by card, not by seat, so users are unlimited on every plan. The Free plan is $0 a month for up to 10 cards. Growth is $250 a month billed annually, or $291 month-to-month, and covers 250 cards at $1 a card. Pro is $500 a month billed annually for 500 cards, plus AI-tuned kanban quantities and multi-card loops. Enterprise is custom. Paid plans include a 7-day free trial, and annual plans add 2 free months and a $650 welcome kit after an onboarding call. You can start with ten cards on one weld cell and expand across the shop when you are ready, with no months-long implementation. See full pricing.
