HFIS-400C Precision Spot Welding Machine
Product Overview
Different metal materials require specific spot welding processes.
The HFIS-400C precision spot welding machine is engineered for
applications where material type, weld position, and joint
consistency must be considered together. Beyond common steel and
stainless steel welding, this machine handles non-ferrous metals
including copper, silver, nickel, and their alloys. For automotive
manufacturing, it's suitable for high-strength steel, hot-formed
steel, galvanized sheet, and nut or bolt projection welding.

Key Features
Precision Resistance Spot Welding
The HFIS-400C is designed for resistance spot welding where
controlled electrical energy and electrode pressure form welded
joints between metal components.
Wide Material Compatibility
This machine welds various conductive materials including:
- Steel and iron
- Stainless steel
- Copper
- Silver
- Nickel
- Metal alloys
- Galvanized sheet
- High-strength and hot-formed steel
Actual welding suitability should be confirmed through sample
testing based on material grade, thickness, joint structure, and
required weld strength.
Suitable for Automotive Sheet Metal
The HFIS-400C is ideal for spot welding and projection welding
applications involving high-strength steel, hot-formed steel, and
galvanized sheet commonly used in automotive components.
Supports Nut and Bolt Projection Welding
This machine handles projection welding of nuts and bolts, with
process parameters depending on projection geometry, workpiece
thickness, material combination, and required joint strength.
Compact Precision Welding Platform
The HFIS-400C provides a dedicated machine platform for
applications requiring repeatable resistance welding rather than
general-purpose manual setups.
How Precision Spot Welding Works
Resistance spot welding forms joints by passing electrical current
through contact areas between metal components while applying
electrode pressure. The process includes: workpiece positioning,
electrode contact, pressure application, welding current, weld
formation, holding, and electrode release. For projection welding,
projections on nuts, bolts, or workpieces concentrate current and
pressure at defined contact points. Welding parameters should be
established through testing as different materials, coatings,
thicknesses, and joint structures create varying welding
conditions.
Precision Spot Welding for Different Metals
Steel and Stainless Steel
These common resistance welding materials benefit from the
HFIS-400C's repeatable electrode contact and controlled welding
conditions.
Copper and Copper-Based Components
Copper's high electrical and thermal conductivity requires specific
electrode configuration and welding parameters evaluated according
to component structure.
Silver and Nickel Components
When welding silver and nickel used in conductive and electrical
components, the process balances joint strength, electrical
performance, and surface condition.
Galvanized Sheet
The zinc coating on galvanized steel influences electrode-workpiece
contact, making appropriate welding parameters and electrode
maintenance crucial for consistent production.
Automotive Spot and Projection Welding
The HFIS-400C applies to automotive manufacturing processes
involving:
- High-strength steel components
- Hot-formed steel parts
- Galvanized sheet components
- Nut projection welding
- Bolt projection welding
- Sheet-metal assemblies
- Conductive metal components
For automotive production, the welding machine should match actual
component geometry and production method. Dedicated fixtures and
electrodes ensure repeatable positioning and controlled electrode
access.
