Linlong Welding
Linlong builds MMA, TIG and MIG/MAG welding machines and plasma cutters in Wenling, Zhejiang, and has worked in welding and cutting equipment since 1993. Before asking for a price, pick the process and send your supply voltage, phase and arc-on work pattern, so Linlong can quote one exact model and package.

What Linlong makes
Linlong's catalogue is split into four machine groups: MMA, TIG, MIG and plasma cutting. Accessories sit in a separate group. The TIG range is further divided into MOSFET and IGBT families, and the stick-welding machines are inverter units. MIG/MAG equipment comes in several model families for gas-shielded wire welding.
The company describes itself as a Wenling business that handles R&D, manufacturing, sales and service in-house. It names home projects, hardware work, vehicle modification and equipment maintenance as typical uses. Those uses cover everything from a light repair machine to a fabrication power source, so the range spans quite different supply circuits, consumables and cooling needs. Tell Linlong the joint and the workload, and ask for the model revision and package contents that match it.

Company background and the provincial R&D centre
Zhejiang Linlong Welding Equipment Co., Ltd. has focused on welding and cutting equipment since 1993. Linlong gives its facility area as approximately 28,000 square metres.
Zhejiang Science and Technology Brain, a provincial government database, lists an R&D centre for intelligent, multifunctional digital welding equipment. Linlong is named as the supporting company, located in Wenling, Taizhou. The centre works on intelligent, automated and digital welding technology. The company name and town in that record match Linlong's own introduction, which helps a buyer confirm they are dealing with the right legal entity. The record covers the centre itself. Product test reports and export documents come from Linlong for each model.
Pick the process first, then the model
Stick welding: start from the electrode classification, electrode diameter, welding position and the current you expect to run. A compact MMA unit that is easy to carry may handle a much lighter continuous load than a larger shop machine.
TIG: state whether the job needs DC or AC output, pulse control, which arc-starting method and whether you want remote current adjustment. Check each of these on the model sheet, since a TIG prefix in a model name says nothing about which functions are fitted.
MIG/MAG: give the material, wire classification, wire diameter, shielding gas and reel size. Ask whether the wire feeder is built in or separate, and whether the quoted torch, liner and drive rolls suit your wire.
Plasma cutting is a cutting job with its own requirements. Brief it separately with the workpiece, the air supply and the cut quality you need.

Match input supply and duty cycle to your shop
Linlong lists machines at several current ratings and supply configurations. Send the voltage, phase and frequency at the installation, the circuit capacity available, any generator you plan to use and the cable run from the supply to the workstation. Ask your electrician to size protection and earthing from the exact model's input data. Output amperage on its own is too little to size a circuit.
Compare duty cycle between machines only when the test conditions match. If a model table states the rating at a given temperature and time basis, keep those conditions next to the current figure. Where the reference current is missing, ask Linlong for it rather than reading the maximum from the model name. The nameplate on the delivered unit should carry the same figures. Rate the torch, leads and feeder too, especially when a high-output source arrives with a lighter accessory set.

Spell out the package and the after-sales support
With a catalogue this broad, a full bill of supply matters. Ask for a quotation that itemises the power source, the torch or holder, the earth clamp, cables, consumables, regulator, wire feeder and any remote control, and marks each item as included or optional. Product photos often show accessories that ship only as extras.
Maintenance buyers should ask for model-specific spare parts and a support plan. Agree who diagnoses a fault, how a replacement board or torch part is identified and whether the service manual matches the quoted revision. Importers need the declarations and test reports required in the destination market, a copy of the exact nameplate and the agreed packaging.

Test the machine on your own joints
Pick a few joints that represent the real work, instead of asking whether a machine can weld steel or aluminium in general. Give base material, thickness, joint geometry, position, consumable and the work sequence. Ask Linlong to run a sample weld on the proposed configuration and record the settings. Agree how the sample will be inspected before it is made, and file the result with the model and accessories used.
If you are comparing two offers, run both on the same workpiece under the same conditions. Note setup time, torch access, wire changes and the duty demand alongside weld quality. A productivity claim only means something when it is measured over a set period on comparable work.

Confirm before ordering
Ask Linlong to confirm these points in writing for your order:
The exact model revision, its rated operating range, input supply and duty cycle with the test temperature and time basis.
The bill of supply, with every included and optional item named, plus the spare-parts and service terms for that revision.
Which product declarations, test reports and certificates cover the quoted model in your destination market. A certificate listed by the company may apply to some models or markets only, so match each document to the model and the country.
Stock status and current delivered price for the quoted package, the cycle time agreed for any sample trial, and the inspection criteria for the sample.

Product families serve different tasks. Use the configuration and acceptance questions to request a quotation for the same work.
On a small screen, scroll sideways to read all three columns.
| Product family | Published scope | Before selecting |
|---|---|---|
| MMA welding machines [1] | Inverter stick-welding models in the official range. | Give the electrode classification and compare each model's duty rating with your real work pattern. |
| TIG welding machines [1] | Grouped in the catalogue as MOSFET and IGBT TIG families. | Check AC/DC output, arc-starting method, pulse and the torch or remote-control package for each model. |
| MIG/MAG welding machines [1] | Gas-shielded wire-welding equipment across several model families. | Give material and wire size; confirm feeder design, reel capacity and the supply circuit needed. |
| Plasma cutters [1] | Listed as a separate group next to the welding range. | Send a cutting brief with workpiece thickness, the edge quality required and your air supply. |

Buyer questions
What does Linlong make?
MMA, TIG and MIG/MAG welding machines and plasma cutting machines, with accessories listed as a separate group. The TIG line comes in MOSFET and IGBT families. Choose the process first, then ask for the model that fits your supply and workload. [1]
How big is the factory and how long has it been running?
Linlong says it has worked in welding and cutting equipment since 1993 and gives its facility area as about 28,000 square metres. Both figures come from the company's own introduction, so ask about current output and lead time when you request a quote. [1]
What is the provincial R&D centre listing?
Zhejiang Science and Technology Brain names Linlong as the supporting company of an R&D centre for intelligent, multifunctional digital welding equipment in Wenling, Taizhou. It confirms the company name and location. For product compliance, request the declaration or test report for your model and destination. [2]
Can I choose a machine from the current figure in its name?
Use the model name to identify the product. Then compare rated operating range, input supply, duty cycle and the exact configuration. The maximum current in a name tells you little about continuous operation or about how the machine suits your joint. [1]
Are accessories and spare parts included?
That depends on the offer. Ask for a named bill of supply and for spare-parts and service terms tied to the quoted model. [1]
