Inverter DC Welding Power Supply

Product Overview

This inverter DC welding power supply is engineered for controlled, repeatable resistance welding where current stability, fast response, and documented process confirmation are essential. The equipment combines a built-in inverter transformer with constant-current load control, enabling the welding process to be governed around the commanded current rather than relying on uncontrolled output behavior. Its 4KHz high-frequency modulation supports responsive control for demanding production tasks.

The system is suited to battery tab and busbar joining, plated metal components, electrical contacts, precision sheet-metal assemblies, and other resistance welding processes that require carefully sequenced energy delivery. Two-stage current programming, adjustable upslope and downslope functions, and eight selectable welding conditions give process engineers practical control across differing materials, coatings, thicknesses, and joint designs.

Built for industrial operating environments, this unit uses forced-air cooling and provides a clear 20 x 4-line LCD interface for welding information and parameter review. Current monitoring compares actual welding results with configured limits, then provides a GO or NG result signal. This supports disciplined process verification, rapid parameter changes, and consistent operation under production-focused welding requirements.

Key Features

• Constant-Current Load Control: The equipment uses load-current constant-current control to support high-quality welding control. Maintaining control around the load current helps create a more consistent welding condition when repeatability is a primary process requirement.

• 4KHz High-Frequency Inverter Control: High-frequency modulation at 4KHz provides fast control response for welding applications. This responsive inverter architecture is designed to support quality-focused welding control where programmed timing and current delivery must be managed closely.

• Two-Stage Energization Sequence: Two independently programmed current stages enable a more adaptable welding sequence. This feature is useful for overcoming the influence of plated workpieces and for adapting the energy profile to varied process requirements.

• Programmable Upslope and Downslope: Adjustable current rise and fall periods allow the welding profile to be shaped around the joint and process. Gradual transitions are intended to help suppress spatter during welding while giving operators more control over the applied current sequence.

• Eight Selectable Welding Conditions: Eight welding condition modes allow approved parameter sets to be switched quickly during operation. This supports organized production workflows when multiple workpiece types, welding requirements, or validated settings must be handled on the same process line.

• Comprehensive Timing Control: The sequence includes squeeze, first-current, cooling, second-current, and hold stages, plus programmable rise and fall periods for each current stage. This level of timing control enables process-specific setup instead of a single fixed energization pattern.

• 20 x 4-Line LCD Process Visibility: The LCD displays multiple welding information items and welding parameters. Operators can confirm setup values and welding-result information directly at the equipment, supporting faster checks during setup and production.

• Current Monitoring with GO/NG Judgment: Actual welding current can be monitored against freely configured limits around the set current. The system produces a GO indication when the measured current remains within the setting and an NG indication when it exceeds the configured range.

• Open-Collector Result Interface: GO/NG judgment is available through open-collector output at the I/O connectors. This provides a defined electrical result output for connection to external production equipment, indicators, or process-control arrangements within the stated interface rating.

• Forced-Air Cooling Construction: Forced-air cooling supports operation at the specified maximum duty cycle. The cooling approach is matched to the equipment's high-current welding role and helps maintain operational continuity in controlled industrial use.
