This is what a buyer checks before they shortlist a metals and metalworking supplier.
What does a fabricator check before buying welding equipment?
They check the duty cycle at the current they actually weld at, the processes supported, and the input power requirement against their shop. Duty cycle at a stated current is the specification that separates machines that look identical on price.
A fabrication shop is replacing machines that fail mid-shift and is trying to avoid repeating the mistake.

What does a fabricator check before buying welding equipment?
What a buyer needs to identify the product
These are the fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Welding processes supported
The primary filter for any fabricator.
- 2
Output current range
Determines the thickness range the machine can handle.
- 3
Duty cycle at stated current
The figure that actually separates machines.
- 4
Input power requirement
Single or three phase, and the supply the shop has.
- 5
Weight and portability
Site work and shop work need different machines.
- 6
Control features
Pulse, synergic and waveform control affect quality and ease of use.
- 7
Wire feeder and torch compatibility
Consumables and accessories lock buyers in or out.
The documents buyers ask for
Not all of them belong on a public page. Naming the ones you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Technical specification sheetAsked at: shortlisting | Output range, duty cycle, input power, weight and processes | Publish it |
| Duty cycle chartAsked at: technical comparison | Output against duty cycle across the range, not a single figure | Publish it |
| Declaration of ConformityAsked at: before shipment to regulated markets | Conformity with the applicable safety and electrical directives | Publish it |
| Electrical safety test certificateAsked at: site approval | Compliance with the arc welding equipment safety standard | Publish it |
| Warranty termsAsked at: before purchase | Coverage period, what is excluded and where service is performed | Publish it |
| Spare parts availability statementAsked at: total cost evaluation | How long parts remain available after a model is discontinued | Publish it |
| Service network coverageAsked at: purchase decision | Where machines are repaired and typical turnaround | Publish it |
Where welding equipment sites lose the enquiry
Each of these is common, cheap to fix, and costs an enquiry that never arrives — so nobody ever reports it.
A single duty cycle percentage with no current stated
Duty cycle only means something at a named output. A bare percentage is the most common way welding machines are made to look comparable when they are not.
No spare parts availability commitment
Fabricators keep machines for years. Not knowing whether parts will exist in five years pushes them to established brands by default.
Service network not described
A machine down mid-shift stops work. Buyers weight repair turnaround heavily and read silence as no network.
What the enquiry form should ask
A form that collects these can be answered properly the first time. A form that collects a name and a message cannot.
Enquiry form — welding equipment
Enough to reply usefully, short enough that a buyer finishes it.
- Processes and materials welded
- Determines the machine family.
- Material thickness range
- Sets the output requirement.
- Usage pattern
- Occasional and continuous production need different duty cycles.
- Available power supply
- A hard constraint that is easy to overlook.
- Shop or site use
- Portability changes the recommendation.
- Number of machines and timing
- Drives commercial terms.
Questions suppliers ask
Why publish a duty cycle chart rather than a single figure?
Because a single figure is chosen to flatter. A chart of output against duty cycle lets a fabricator find the point they actually weld at and compare machines honestly. Publishing one signals that your machine performs where it matters, not only at the point that makes the datasheet look good.
How much should we say about consumables and lock-in?
Be explicit about which torches, feeders and consumables fit. Buyers are wary of being locked into a proprietary chain and finding out later, and a supplier who states compatibility openly is trusted more than one who leaves it to be discovered.
What matters most to a shop replacing failed equipment?
Evidence about reliability and repair, not features. Duty cycle at real currents, warranty scope, parts availability and where machines get repaired. A buyer replacing a machine that failed is buying against a specific bad experience, and those four facts address it directly.
Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
