DTB-80 Industrial Vertical Medium Frequency Inverter Spot Welder
DTB-80 Industrial Vertical Medium Frequency Inverter Spot Welder delivers stable and precise spot welding with advanced inverter technology. Designed for industrial sheet metal, cabinets, and metal component manufacturing with high consistency.
DTB-80 Industrial Vertical Medium Frequency Inverter Spot Welder
Product Overview
The DTB-80 Industrial Vertical Medium Frequency Inverter Spot Welder is a vertical resistance spot welding machine designed for high-efficiency, high-quality welding of various metal components. By converting 50 Hz AC power into a 1000 Hz medium-frequency DC output, the machine delivers faster response, more precise current control, and stable welding performance.
Compared with traditional power-frequency spot welding machines, the DTB-80 offers higher energy efficiency, shorter welding time, and more consistent welding quality. A 25 kA maximum short-circuit current, 6000 N electrode pressure, and 80 mm electrode stroke make it suitable for a wide range of sheet metal and metal component welding tasks, including aluminum, copper, galvanized sheet, carbon steel, and nickel parts.
It is an ideal solution for manufacturers looking for stable, efficient, and cost-effective resistance welding equipment for industrial sheet metal, cabinets, and metal component manufacturing.
How It Works
The welding system converts input power through a precise, controllable sequence: 50 Hz AC input → medium-frequency inverter → 1000 Hz DC output → precise welding current.
The workpiece is positioned between the electrodes, and the welding controller applies the programmed welding current, welding time, and electrode pressure. Because the inverter delivers DC output at 1000 Hz, the current rises faster and stays more stable than in a power-frequency machine, so each welding point is formed under repeatable conditions.
Key Features
1. 1000 Hz Medium Frequency Inverter DC Output. Converting 50 Hz AC into 1000 Hz medium-frequency DC provides faster response, more precise current control, and more stable welding performance than conventional power-frequency systems.
2. High Efficiency Welding Performance. Precise control of welding current and welding time maintains stable welding results even during continuous production.
3. Energy Saving. Higher electrical and thermal efficiency helps reduce operating costs compared with power-frequency AC spot welders.
4. Fast Welding Speed. High output power enables short welding cycles and high production efficiency.
5. Stable Welding Current. DC output provides consistent welding performance and repeatable weld quality from piece to piece.
6. Strong Welding Capability. A 25 kA maximum short-circuit current and 6000 N electrode pressure handle demanding joints, including 2.5 + 2.5 mm carbon steel and 2.0 + 2.0 mm aluminum.
7. Vertical Structure with Extended Arm. The vertical machine structure with a 500 * 250 mm arm extension and 80 mm electrode stroke provides good access to different workpiece shapes and welding positions.
8. Water-Cooled for Continuous Production. Water cooling at 12 L/min keeps the electrodes, arms, and transformer at stable temperature, supporting demanding continuous industrial welding.

Medium Frequency Inverter DC Welding vs. Power-Frequency AC Welding
| Feature | Medium frequency inverter DC (DTB-80) | Power-frequency AC welder |
|---|---|---|
| Welding current | Stable DC output | Alternating AC output |
| Response speed | Fast (1000 Hz inverter) | Slower (50 Hz) |
| Current control accuracy | High, precise | Limited |
| Energy efficiency | Higher | Lower |
| Welding cycle time | Shorter | Longer |
| Weld consistency | High, repeatable | More affected by power fluctuations |
| Oxidation and deformation | Reduced | More likely |
Clean and Strong Welding Results
The controlled DC welding current produces uniform and firm welding points with low oxidation and reduced deformation. For suitable applications and properly selected welding parameters, the welding surface can remain clean with minimal visible marks, reducing the need for additional finishing processes.
Stable current + precise welding time + proper electrode pressure = consistent welding quality.

Frequently Asked Questions
Q1: What is the difference between a medium frequency inverter welder and a power-frequency AC welder?
A: A power-frequency welder uses 50 Hz AC output, so the welding current rises more slowly and is more affected by power fluctuations. The DTB-80 converts the input into 1000 Hz medium-frequency DC output, giving faster response, more precise current control, higher energy efficiency, shorter welding cycles, and more consistent weld quality.
Q2: What materials and thicknesses can it weld?
A: The machine welds carbon steel up to 2.5 + 2.5 mm and aluminum up to 2.0 + 2.0 mm, and is also suitable for copper, galvanized sheet, nickel, tungsten, enameled wire, flexible copper connections, and inductive coils. Parameters are selected according to the material, thickness, and workpiece structure.
Q3: Why does the machine need water cooling?
A: Continuous industrial welding generates heat in the electrodes, arms, and transformer. A cooling water flow of 12 L/min keeps temperatures stable, which protects the welding transformer and maintains consistent weld quality during long production runs.
Q4: Can it be used in automated production lines?
A: Yes. The precise current control and stable DC output of the inverter system make the machine suitable for repetitive and automated production, where consistent welding conditions between cycles are essential.
Q5: What is the delivery time, minimum order quantity, and payment terms?
A: The minimum order quantity is 1 unit. Standard packaging is a wooden case, the typical delivery time is 14 working days, and payment terms include L/C, D/A, D/P, and T/T.
