Customer Requirements and Equipment Configuration
The customer is a metal products manufacturer in Hangzhou whose parts are welded from steel sheet in moderate thicknesses, and whose production needs a spot welder that is compact enough for a manual welding station yet precise enough for consistent joints. For this kind of work the machine must hold the current steady, repeat the electrode force exactly, and stay simple enough that the existing team can run it without a dedicated welding engineer.
The customer selected the DTB-80 vertical MF spot welder, a vertical medium frequency inverter machine whose press-type welding head closes straight down on a rigid column. The medium frequency inverter control rectifies the supply into regulated DC welding current with real-time feedback, which keeps nugget formation uniform on thin and medium sheet and keeps electrode marks shallow.
The machine was supplied as a complete working station: the welder itself, a matching recirculating water chiller for the electrode cooling circuit, and the accessories and documentation needed for commissioning, all packed for transport to Hangzhou.
The customer needed a welding solution that could provide:
- A compact vertical spot welder for daily sheet metal spot welding
- Uniform nuggets with shallow electrode marks on visible parts
- Consistent pneumatic electrode force on every cycle
- A water chiller included in the delivery for electrode cooling
- Touch-screen schedule control for different part types
- Safe transport packing for road delivery
- Quick commissioning at the customer’s own plant
Buying a spot welder as separate loose items is where delivery projects usually go wrong: a chiller that does not match the machine, missing electrode hardware or undocumented settings turn commissioning into weeks of trial and error. And if the machine itself cannot hold current and force steady, the result shows up later as cold joints and rework that cost far more than the original price gap.
DTB-80 Vertical MF Spot Welding Solution and Delivery Scope
The DTB-80 vertical medium frequency inverter spot welder delivered to Hangzhou combines a pneumatic press-type welding head, a rigid vertical column and medium frequency inverter current control. The orange controller cabinet carries the touch-screen panel on which weld schedules are stored and recalled, while the foot pedal starts each cycle so the operator keeps both hands free for loading parts.
The delivery includes a matching recirculating water chiller, shown packed in front of the machine before loading. The chiller supplies the electrode cooling circuit that keeps tips and conductive members within a safe working temperature during production, protecting both weld quality and electrode life.
For transport, the machine and chiller were fixed to a shipping pallet, protected with foam, and closed inside a plywood export crate marked for the customer. The crate was loaded into the delivery truck at the PDKJ factory for the road transport to Hangzhou.

How the Machine Solves Customer Pain Points
1. Compact Footprint for Manual Welding Stations
The DTB-80 occupies the floor space of a single workstation, so it fits into an existing shop layout without rearranging the line. For a metal products plant adding welding capacity station by station, this footprint is often the deciding factor.
2. Uniform Nuggets With Controlled Electrode Marks
Medium frequency inverter control holds the welding current at the set value with fast feedback, so nuggets form consistently across the sheet joints, and the pneumatic head applies force evenly, keeping the marks on the visible surfaces light and uniform.
3. Cooling Included, Not an Afterthought
The matching water chiller ships with the machine in the same delivery, so the electrode cooling circuit works from the first day of production. This removes the common failure mode of machines run without adequate cooling, which shortens electrode life and destabilizes welds.
4. Simple Schedule Control for the Existing Team
Weld schedules are stored on the touch-screen controller and recalled per part type, so the customer’s existing operators can run different jobs without re-tuning. Supervisors keep control of parameters while operators only select the schedule and weld.
5. Transport Protection for Road Delivery
Foam wrapping, a plywood export crate and pallet fixing protected the machine through loading and road transport, so it arrived in Hangzhou ready to unpack, level and connect rather than needing repairs or claims.
6. One Supplier, One Complete Station
Welder, chiller, accessories and documentation come from PDKJ as one delivery scope. Responsibility for the working station rests with one supplier, which simplifies both commissioning and any later service questions.
Welding Process
The welding process can generally be organized as:
Order Confirmation and Configuration → Assembly and Testing at the PDKJ Factory → Foam Wrapping and Plywood Export Crate Packing → Loading Into the Delivery Truck → Road Transport to Hangzhou → Unpacking and Machine Leveling at the Customer Plant → Chiller and Utility Connections → Trial Welds and Parameter Setup on Customer Parts
Before production, welding parameters can be adjusted according to the material, workpiece structure, joint geometry, and required joint performance.
Why Choose a DTB-80 Vertical MF Spot Welder?
The DTB-80 vertical MF spot welder is built for plants that need dependable spot welding in a compact, operator-friendly format: medium frequency inverter current control for consistent nuggets, a pneumatic press head for repeatable force, and a foot-pedal cycle for hands-free loading of sheet parts.
Delivered with its own water chiller, the machine forms a complete cooling and welding station out of the crate, which is what keeps the gap between delivery and production short for the Hangzhou customer.
This machine class suits metal products manufacturers, hardware workshops and sheet metal shops welding small and medium steel parts. PDKJ builds the DTB series of vertical medium frequency inverter spot welders in several capacities, and advises on the right class for the parts in question.
Key Advantages
- Compact vertical design for single-station installation
- Medium frequency inverter control with regulated DC output
- Pneumatic press head with repeatable electrode force
- Touch-screen controller with stored weld schedules
- Matching water chiller included in the delivery
- Foot-pedal cycle start with both hands free
- Factory-tested machine and cooling unit as one scope
- Foam and plywood export packing for safe transport
- Fast commissioning on the customer’s own parts
Potential Applications
The same welding concept can be considered for various applications, including:
- Small and medium steel sheet parts
- Hardware products and fittings
- Sheet metal housings and covers
- Wire products welded to sheet or plate
- Furniture steel components
- Electrical brackets and mounting plates
- Appliance sub-assemblies in thin sheet
- General repair and job-shop spot welding
Actual welding capability depends on the material, thickness, joint structure, electrode or fixture configuration, and production requirements.
From Delivery to Production
The machine and chiller were checked together as one working station at the PDKJ factory before packing, so the customer in Hangzhou receives equipment whose welding and cooling sides are already proven to run as a pair.
The packing and loading photos from September 8 show the actual delivery: the DTB-80 with its controller, the chiller protected in foam, and the plywood crate closed and loaded for road transport.
At the customer’s plant, the remaining steps are unpacking, utility connections and trial welds on the customer’s own parts, with parameters adjusted on site to the material and joint geometry in question.
