HFBP-200 Medium Frequency AC Spot Welding Machine
Different materials require different welding conditions.
High-strength steel, galvanized sheet, aluminum, copper wire and
electrical contacts do not respond to the same current, pressure
and welding time.
The HFBP-200 is designed as a medium frequency AC resistance
welding machine for production environments where the welding
process needs controlled electrical output, stable electrode
pressure and repeatable welding results.
With a rated capacity of 200 kVA and maximum short-circuit current
of 43 kA, the machine provides the welding capacity required for a
range of metal component applications. Its configuration can be
adapted to the workpiece, welding position and production
requirements.
Rather than selecting a spot welder only by its rated power, the
actual material combination, thickness, electrode geometry and
required weld points should be considered when determining the
final setup.

Key Features
- 200 kVA Rated Welding Capacity: The HFBP-200 has a rated capacity of 200 kVA, providing a
higher-capacity configuration for applications requiring
substantial welding output.
- Maximum Short-Circuit Current of 43 kA: The maximum short-circuit current is specified at 43 kA. The
actual welding current used in production should be determined
according to the material, thickness, electrode and joint
requirements.
- Medium Frequency AC Welding System: The machine uses a medium frequency AC welding configuration for
resistance welding applications involving different metal
components.
- 20% Rated Duty Cycle: The rated duty cycle is 20%, providing a defined operating
reference for equipment selection and production planning.
- Multiple Material Applications: The HFBP-200 can be evaluated for steel, stainless steel,
galvanized sheet, aluminum, copper wire and contact components,
allowing one machine platform to serve different production
requirements when suitable tooling and welding conditions are used.
- Cooling Water System: The specified cooling water consumption is 35 L/min. Cooling
requirements should be incorporated into the plant utility planning
before equipment installation.
Spot Welding for Different Materials
High-Strength and Hot-Formed Steel
Automotive components made from high-strength and hot-formed steel
require controlled welding conditions because the material
properties differ from conventional mild steel. The HFBP-200 can be
applied to spot welding and nut projection welding for suitable
automotive components.
Galvanized Steel
Galvanized sheet requires consideration of the zinc coating,
electrode condition and welding parameters. The process should be
developed to achieve the required joint strength while controlling
electrode wear.
Aluminum Sheet
Aluminum has higher electrical and thermal conductivity than steel,
so the welding process requires different current and pressure
conditions. The HFBP-200 can be evaluated for aluminum sheet spot
welding according to the actual material thickness and joint
design.
Copper Wire and Electrical Components
The machine can also be used for resistance brazing and spot
welding of copper wire in suitable electrical applications.
Silver and Copper Contacts
Silver contacts, copper plates and composite silver contacts can be
welded or brazed according to the component structure and required
connection.
Applications
Automotive Manufacturing
The HFBP-200 can be used for spot and projection welding of
high-strength steel, hot-formed steel and other automotive sheet
components. Typical applications may include structural sheet
assemblies, brackets and components requiring repeatable resistance
welds.
Electrical and Low-Voltage Components
The machine is suitable for applications involving copper wire,
silver contacts, copper plates and other conductive components.
Household Electrical Products

Sheet Metal Components
Low-carbon steel, stainless steel and galvanized sheet components
can be processed using suitable electrodes and welding parameters.
Aluminum Components
For aluminum sheet and conductive aluminum parts, the welding
process can be developed according to material thickness, joint
configuration and required weld strength.
