Stationary Pedal-Operated Spot Welder for 6+6 mm Sheet Metal Fusion

Video Demonstration

Product Overview for Production Buyers

This stationary spot welder delivers dependable resistance welding for sheet metal up to 6+6 mm combined thickness, engineered for workshops that demand repeatable joint quality and minimal cycle time. The pedal-operated electrode actuation gives operators precise control over weld pressure, while the rigid C-frame structure minimizes deflection during high-force cycles—ideal for continuous production runs in metal fabrication and light industrial assembly.

Built around a high-magnetic silicon steel transformer with forced internal water cooling, the machine sustains a 50% duty cycle even under heavy workloads. A microcomputer control system stores up to 16 welding schedules, allowing quick changeover between different material thicknesses and joint configurations without manual recalibration. This combination of durability, programmability, and pedal precision makes it a practical choice for manufacturers seeking consistent output with low maintenance overhead.

Key Technical Advantages

High-Force Electrode Pressure with Assistant Stroke

The upper and lower electrode arms apply pressure through an assisted-stroke mechanism, delivering electrode force up to 12,000 N for firm fusion on mild steel, stainless steel, and galvanized sheets. This design shortens the squeeze time and improves weld nugget consistency across repeated cycles.

Forced Water-Cooled Transformer for Extended Operation

The specialized resistance-welding transformer uses high-permeability silicon steel laminations with forced internal water circulation. This keeps thermal rise low during continuous production and supports a rated duty cycle of 50%, so the machine handles long shifts without power dropout.

Microcomputer Control with 16 Preset Welding Schedules

Operators can store up to 16 sets of welding parameters—current, time, and pressure—covering different sheet thicknesses and material types. Switching from one job to another is a matter of selecting a saved schedule, reducing setup time and operator error.

Flexible Power Range for Diverse Production Needs

Available in 40, 63, 80, 100, 125, 160, and 200 kVA configurations, this spot welder scales to match your production volume and material thickness. Lower-rated units suit light-gauge fabrication, while higher ratings handle demanding structural and heavy-sheet applications.

Low Maintenance Cost and Easy Serviceability

With no complex hydraulic system and a proven mechanical pedal linkage, routine maintenance is limited to electrode dressing and periodic water-line checks. Core components—the transformer and control board—are covered by a 3-year warranty, reducing total ownership cost.

Frequently Asked Questions

What is the maximum welding thickness this machine can handle?

The standard configuration welds mild steel sheets up to 6+6 mm combined thickness. For thicker or coated materials, we recommend consulting our engineers, who can adjust the transformer rating and electrode design to optimize nugget quality.

Can the control system store multiple welding programs?

Yes, the microcomputer control stores up to 16 independent welding schedules. Each schedule can hold a distinct combination of welding current, squeeze time, and hold time, enabling quick changeover between different sheet thicknesses or material grades.

What certifications does your factory hold?

Our factory is certified with CE, CCC, and ISO, and we provide machinery test reports and video-based outgoing inspection before shipment. Certification documents are available upon request.

How long is the standard delivery time?

Standard models ship within 15 days after receiving the deposit. Customized machines may take longer depending on engineering scope and configuration changes; we will confirm the lead time before you place the order.

Can you send an engineer to help with installation?

Yes, we provide overseas installation and training services. Our engineer can visit your facility to commission the machine, train your welding operators, and verify production readiness before returning.
