Customer Requirements and Equipment Configuration

The customer is a sheet metal fabrication company in Suzhou that welds steel assemblies in daily production and needed to extend its resistance welding capacity. For assemblies that combine appearance surfaces with structural joints, the welding current has to stay stable through long shifts, and the electrode force has to be identical on every cycle, so the machine choice came down to control quality rather than price alone.

After reviewing the options, the customer selected the DTB-160 vertical MF spot welder, a vertical medium frequency inverter machine in which the welding head closes straight down on a rigid frame and the welding current is regulated as rectified DC with real-time feedback. This combination gives uniform nuggets on sheet metal joints and keeps the electrode marks shallow enough for parts that are visible in the final product.

The machine was configured, tested and packed at the PDKJ factory and shipped complete with its water cooling circuit, accessories and documentation, so the customer could move from delivery to trial welds without waiting for extra components.

The customer needed a welding solution that could provide:

A vertical spot welder sized for sheet metal assembly welding in daily production
Stable, repeatable weld current through long production shifts
Consistent pneumatic electrode force for uniform nugget formation
A water-cooled electrode circuit for sustained duty cycles
Simple schedule control that shop-floor operators can manage
Export-grade packing so the machine arrives ready to install
Delivery scope complete with accessories and documentation

A spot welder that arrives under-configured or damaged in transport costs far more than the price difference at purchase: installation is delayed, trial production slips, and every day without welding capacity pushes deliveries back. Just as damaging is a machine whose current sags or whose force drifts during long shifts, because inconsistent nuggets surface later as assembly failures and customer complaints rather than as immediate, fixable faults.

DTB-160 Vertical MF Spot Welding Solution and Delivery Scope

The DTB-160 vertical medium frequency spot welder supplied to Suzhou is built around a vertical press-type welding head driven by a pneumatic cylinder, mounted on a rigid machine column. The medium frequency inverter control delivers regulated DC welding current, and the touch-screen controller stores weld schedules so operators can switch between assemblies without re-tuning each time.

For sustained production duty, the machine is fitted with a water-cooled electrode circuit, and the photographed water flow indicator manifold lets the operator confirm at a glance that cooling water is circulating through the electrodes and conductive members. The pneumatic system, including the air tank mounted on the machine body, stabilizes electrode force and closing speed from weld to weld.

Before packing, the machine was assembled, wired and function-tested at the PDKJ factory. It was then wrapped in protective foam and stretch film, fixed to its shipping pallet and closed inside a plywood export crate, with the accessories kit and documentation packed alongside the machine base.

How the Machine Solves Customer Pain Points

1. Machine Class Matched to the Application

The DTB-160 is a vertical medium frequency machine sized for sheet metal assembly work, so the customer receives a welder whose frame, head travel and cooling are designed for production shifts rather than occasional repair welding. Matching the machine class to the job is the first safeguard against under-capacity later.

2. Consistent Weld Current Through Long Shifts

Medium frequency inverter control holds the set welding current steady even as line voltage and electrode conditions change, which keeps nugget size uniform from the first spot of the shift to the last. That consistency is what the customer needs when joints must pass both pull tests and appearance checks.

3. Water-Cooled Electrodes for Continuous Duty

Electrodes and conductive members heat up during volume production, and heat is the enemy of both weld quality and electrode life. The water-cooled circuit with its flow indicators keeps the working temperature down, extending tip life and reducing the frequency of electrode dressing stops.

4. Simple Operation for Shop-Floor Teams

Weld schedules are selected on the touch-screen controller and cycles start from the foot pedal, so a trained operator can run the machine after a short introduction. Parameter changes remain in the hands of the supervisor instead of depending on individual operator settings.

5. Export-Grade Packing for Transport Protection

The machine was foam-wrapped, film-sealed and packed in a reinforced plywood crate before transport to Suzhou, protecting the painted surfaces, the welding head and the controller from handling shocks, so it arrived ready to level, connect and start.

6. Complete Delivery Scope With Accessories and Documentation

Electrode hardware, tools, documentation and packed accessories shipped with the machine in the same crate. The customer does not need to chase separate items before commissioning, which shortens the path from delivery to trial welds.

Welding Process

The welding process can generally be organized as:

Order Confirmation and Configuration → Assembly and Wiring at the PDKJ Factory → Function and Weld Testing Before Packing → Foam Wrapping and Plywood Export Crate Packing → Accessories and Documentation Packed With the Machine → Transport to Suzhou → Unpacking, Installation and Power-Up at the Customer Plant → Trial Welds and Production Handover

Before production, welding parameters can be adjusted according to the material, workpiece structure, joint geometry, and required joint performance.

Why Choose a DTB-160 Vertical MF Spot Welder?

A spot welder for production welding is judged on three things: whether the current stays where it is set, whether the force repeats every cycle, and whether the machine survives the duty. The DTB-160 vertical MF spot welder addresses all three with its inverter control, pneumatic press head and water-cooled electrode circuit.

For the Suzhou customer, this means sheet metal assemblies can be welded with uniform nuggets and shallow, clean electrode marks, shift after shift, without depending on a specialist welder to nurse the machine along. The vertical structure also keeps the work area open for loading flat assemblies and larger parts.

This machine class suits sheet metal fabricators, enclosure manufacturers and assembly plants that need dependable resistance spot welding on steel parts. PDKJ builds vertical and platform-type medium frequency inverter welding machines across a range of capacities.

Actual welding capability depends on the material, thickness, joint structure, electrode or fixture configuration, and production requirements.

From Delivery to Production

Before packing, the DTB-160 was assembled, wired and function-tested at the PDKJ factory, with the controller, pneumatic system and water cooling circuit checked as a complete machine rather than as loose components.

The packing sequence photographed on September 7 shows the same machine the customer ordered: foam-wrapped, film-sealed and closed in a plywood export crate with its accessories, so transport protection is part of the delivery scope instead of an afterthought.

On arrival in Suzhou, the customer can move directly to installation and trial welds, and PDKJ supports parameter setup on the customer’s own assemblies so the machine enters production with proven settings.

Conclusion

The September 7 delivery to Suzhou covers the supply of a DTB-160 Vertical MF Spot Welder for sheet metal welding production, shipped factory-tested and packed in export-grade protective packaging.
