Product Description
The HFTR-5000 is a high-capacity Capacitor Discharge Spot Welding Machine engineered for heavy-duty industrial applications. With a 5000-Joule energy rating, this machine excels at welding high-conductivity metals such as copper, brass, and aluminum alloys. By releasing stored energy in less than 15 milliseconds, it creates a high-intensity weld nugget without the excessive heat buildup that causes workpiece deformation or surface oxidation.
Core Technical Advantages
1.High Energy Density (5000J)
Provides the necessary thermal shock to penetrate thick copper busbars and electrical contacts.
2.Precision Voltage Control
Equipped with a digital charging circuit that maintains a voltage stability of ±0.5%, ensuring consistent weld quality across massive production runs.
3.Minimal Heat-Affected Zone (HAZ)
The ultra-fast discharge prevents heat from spreading to the surrounding material, preserving the temper and finish of the workpiece.
4.Energy Efficiency
Can be operated on a standard factory power grid (20kVA-30kVA), eliminating the need for expensive high-capacity transformers required by traditional AC welders.
Specialized Industry Applications
1.Electrical Switchgear
High-strength welding of copper busbars and silver contacts.
2.New Energy Vehicles (EV)
Joining thick copper/aluminum terminals and battery pack connectors.
3.Power Distribution
Assembly of low-voltage and medium-voltage electrical cabinets.
4.Hardware Manufacturing
Projection welding of fasteners to galvanized steel or stainless steel without marking the reverse side.

FAQ
Q: Can the HFTR-5000 weld copper busbars to steel plates?
A: Yes. The rapid energy release of the HFTR-5000 is ideal for joining dissimilar metals with different melting points and thermal conductivities.
Q: Why is a CD welder better than a traditional AC welder for my factory?
A: A CD welder like the HFTR-5000 draws power slowly to charge the capacitors and releases it instantly. This prevents the "voltage dip" in your factory grid that often occurs with high-kVA AC welders.
Q: Does the machine require water cooling?
A: While the electrodes may require cooling during high-frequency production, the machine itself generates very little internal heat due to its efficient energy storage design.
