What Yixin offers
Yixin's company introduction describes a business that sells special resistance welding machines and dedicated automatic equipment, and services what it sells. The site menu adds domestic and imported welders, robot categories, accessories and welding materials. Read the range as a supply catalogue: some lines may come from Yixin's own team and others from partner brands.
On the resistance welding side, the company lists spot, projection, butt, seam and mesh equipment. It also names dedicated machines for compressor and condenser welding. Yixin mentions quality, export markets and industrial users in general terms. Ask for model data and a reference project for the kind of joint you need.

Seller, maker and integrator: three names to get
For each machine on the quote, ask for three names: the legal seller, the manufacturer and the party that builds any custom station. Find out whose name will appear on the rating plate, the operating manual and the conformity documents. When an offer pairs a standard welding source with a locally built fixture or automatic station, ask who supplies each part and who answers for the finished installation.
This matters most when you compare a branded robot or an imported welder against a dedicated resistance machine. Ask Yixin for a current dealer letter from any brand it offers, and for the service access that comes with it. With the supply chain written down, warranty claims and spare-part orders go to the right party from the start.
Start a resistance enquiry from the joint
Send the material grade, the thickness of each sheet in the stack, the surface condition, the joint positions and the space available for the electrodes. For projection welding, show the projection shape and how the part is located. For seam welding, draw the seam path and any breaks in it. For mesh or dedicated machines, give the wire or bar spacing and how the material is fed. Describe the joint before you talk about machine power.
Ask Yixin to propose the electrode layout, control sequence and utilities for the exact machine. Check whether the price covers tooling and a process trial or only the bare machine. Compare every offer with the same sample set, the same expected work cycle and the same examination method.
Spell out what the station does on its own
For a dedicated station, list which steps should run automatically: loading, locating, clamping, welding, unloading and inspection. Name the steps that stay manual and how much the operator does. If a robot is part of the offer, ask for the layout, the work envelope and the tooling, drawn with your actual part in place.
Bring changeovers and fault recovery into the scope talks. A station that welds one carefully prepared sample may need a lot more work to cope with normal batch variation. Agree who handles programming, fixtures, guarding and commissioning. The quotation should show clearly where the machine builder's work ends, where the integrator's begins and what you supply yourself.
Service after delivery
A sales and service company can help when you need support close to the installation. Ask Yixin for its response times and the area it covers. Find out who diagnoses and repairs faults, which parts are kept in stock nearby and which have to come from the manufacturer. Ask how mechanical and electrical faults are each handled.
For a combined station, check whether the service team looks after the whole cell or only the standard machines it sells. Ask how travel, return freight, software changes and replacement parts are charged. Find out which drawings, manuals and program backups you receive at handover. Judge the service offer by named people, stocked parts and stated response, and give little weight to a general promise of after-sales help.
Trial run and records
Watch a full work cycle with your own materials and the intended tooling. Set the weld and dimensional acceptance rules with your engineering team, and note who ran the trial. File the machine model, settings, electrodes and fixture details with the result. Later you can check the delivered machine against the accepted proposal. Treat the seller's company documents and the trial result as two separate checks: one tells you who you are buying from, the other how the joint welds.
Answers to get from Yixin before signing
Ask Yixin to state in writing whether it builds the quoted machine itself or supplies it from another manufacturer, and to name that manufacturer. Request the manufacturer's documents for the exact model and any brand authorisation the offer depends on. Get the price, delivery date, warranty, certificates and the full integration scope stated in the quotation before you sign.

| Dedicated and robotic automation [1] | Dedicated automation and robot categories appear in the site menu. | Name the integrator and agree who is responsible for fixtures, programming and cell acceptance. |
| Welders, materials and peripherals [1] | Domestic and imported welders, accessories and welding materials are listed as separate categories. | Ask for the exact brand and model, a dealer letter where one is claimed, and spare-part support. |
Buyer questions
Does Yixin manufacture its own welders?
Its own introduction describes a sales and service business with a development team. Ask who builds the exact machine on your quote before you treat the order as factory-direct. [1]
Can Yixin supply imported brands?
Imported welders and robot brands appear in its site menu. If the offer relies on being an authorised dealer, ask for a current letter from the brand and confirm who handles warranty work. [1]
Which resistance processes does Yixin cover?
Spot, projection, butt, seam and mesh welding, plus dedicated compressor and condenser welding machines. [1]
How can I compare Yixin with other suppliers?
Give every supplier the same joint drawings, sample acceptance rules, equipment list and responsibility map. Compare the result each one commits to and the support behind it, and give less weight to the size of the catalogue.
