PLC parameter input
The listed intelligent touch-screen controller allows welding parameters to be entered and read. Product-position coordinates and process settings are used to define the programmed welding track.
01 / Product Overview
Programmed seam welding for stainless steel sink components
The Hwashi WL-FS-100K is presented for stainless steel kitchen sink seam welding. Its resistance seam welding process uses a rotating wheel electrode in place of the conventional cylindrical spot-welding electrode. As the wheel travels along the joint, a sequence of overlapping weld nuggets forms a continuous or intermittent seam according to the selected process settings.
The product description identifies a PLC control system for entering welding parameters and product-position coordinates. Once the workpiece is positioned and the preset program is started, the programmed welding track is carried out by the machine. The operator handles workpiece loading and unloading according to the configured production process.
The page title identifies this listing as a pump-motor type sink bowl maker. The actual pump, motor and auxiliary-system configuration should be confirmed against the final machine layout and approved technical proposal.

03 / Process & Engineering Features
How the resistance seam welding process works
In resistance seam welding, pressure and electrical current are applied through rotating wheel electrodes. A series of weld nuggets is formed along the joint; the degree of overlap and the selected current pattern determine whether the process is configured for roll spot welding or a more continuous, leak-resistant seam. The source description identifies the principal stages as pressurization, heating/fusion and cooling/solidification.
Roller-wheel electrodes
The machine description identifies a copper-alloy wheel electrode. The rotating wheel replaces the conventional spot-welding electrode and supports overlapping weld formation along the joint.
Configured tooling
Electrode geometry, extended arms and product fixtures can be designed around the workpiece shape. Special electrode moulds and welding methods are described as configurable to product specifications.
Horizontal and vertical travel
The general seam-welding description states that the welding wheel can operate in horizontal and vertical directions. The actual travel arrangement depends on the selected machine configuration.
Cooling arrangement
The source describes forced-water circulation cooling for the transformer and welding wheel to support operation under the configured load conditions.
Workpiece handling
The described operating sequence is to locate the workpiece in the designated position, run the preset program and remove the component after the welding cycle is complete.

06 / Applications & Configuration
Workpiece-based machine configuration
The product is listed for stainless steel kitchen sink seam welding. The wider seam-welding platform description also references sheet metal, barrel bodies, boxes and sealed thin-wall containers. Other application examples named by the manufacturer include fuel tanks, motorcycle dampers, temperature-control components, battery nickel strips, water-pump components and metal containers.
For a sink-specific project, the tooling and process should be evaluated against the actual material grade, sheet thickness, joint geometry, sink dimensions, required seam location and production takt. A representative workpiece sample and drawing are useful inputs for process trials and fixture design.
Configuration boundary: The general application list describes the broader seam-welding machine category. It should not be read as confirmation that every listed material, product shape or welding orientation is included in the standard WL-FS-100K configuration.

09 / Buyer FAQ
Technical and procurement questions
1. Can the WL-FS-100K be configured for different sink dimensions and seam positions?
The product description states that machine structure, extended arms, electrode moulds and welding methods can be designed according to the workpiece. Buyers should provide sink drawings, dimensions, material grade, thickness range and seam-location details so the proposed tooling and working envelope can be reviewed.
2. What information is needed to confirm material compatibility and welding quality?
Provide the stainless-steel grade, thickness, surface condition, joint design and sample parts. Welding current, wheel pressure, speed, pulse pattern and cooling conditions should be established through engineering trials. The published minimum thickness of 0.2 mm should be treated as a listing value and validated for the buyer's actual material and joint.
3. How should dimensional tolerances and weld acceptance criteria be agreed?
Define the critical dimensions, allowable distortion, seam appearance, joint strength and any leak-tightness requirement in the technical agreement. A sample-welding evaluation and mutually approved inspection plan should be completed before mass production. No universal tolerance or weld-strength value is assumed in this page.
4. How is the machine protected for sea freight?
The product listing specifies seaworthy wooden packaging. Before shipment, buyers should confirm the packing design, moisture barrier, desiccant, corrosion protection for exposed metal surfaces, immobilization of moving parts, shock protection and the packing-list details for accessories and spare parts.
5. Can inspection records, material certificates or third-party test reports be supplied?
Agree the required document list before order placement. Depending on the supplied materials and project scope, buyers may request a factory inspection record, electrical test record, machine run-off report, sample-welding report or third-party inspection. Material Test Certificates (MTCs) should be requested where material traceability is part of the purchase specification; availability should be confirmed for each item.
6. What is the production lead time and how is delivery scheduled?
The product page publishes a delivery period of 7–30 working days after payment. Actual timing depends on the approved configuration, tooling, component availability and inspection schedule. The purchase contract should state the agreed lead time, shipment readiness date, acceptance milestones and the consequences of schedule changes.
7. What after-sales and technical support should buyers confirm?
Hwashi's company profile describes online troubleshooting, operating guidance and technical support, and states a standard one-year warranty after shipment. Buyers should obtain the warranty terms in writing, including covered components, exclusions, response procedure, remote-support arrangements, spare-parts supply and any on-site service costs.
10 / Before Order Confirmation
Buyer verification checklist
Confirm stainless-steel grade, thickness range and representative workpiece samples.
