Welding Power Supply Trigger Receptacle for Portable Tool Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable welding systems often lack the capability to power additional tools like grinders, which require 115 VAC, making it impractical to use them in remote locations without an available power source.
Innovation Solution
A welding system with a power tool connector configured to receive power from a welding power supply's trigger receptacle, allowing the power tool to operate using low voltage DC power, enabling flexibility in using various tools with the portable welding system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 115 VAC power is brought to the welding location, then power tools can be operated, but the complexity and impracticality of transporting power infrastructure increases
Solution Approach 1:
The invention extracts the power tool operation capability from the requirement for external 115 VAC infrastructure. By separating the power tool power source from the welding power supply and providing it through the DC output, the system eliminates the need to transport complex power infrastructure to remote locations.
Solution Approach 2:
The welding power supply serves itself by providing power not only for welding operations but also for powering external tools through its existing DC output circuitry. The trigger receptacle and control circuitry are designed to automatically manage power distribution to both welding and tool operations without requiring external power infrastructure.
2Adaptability or versatility
If the trigger receptacle is used to provide power to power tools, then the wire drive system power is affected, but the trigger receptacle is the available power interface
Solution Approach 1:
The power delivery system is designed to be dynamic, automatically adjusting power distribution based on the connected load. When a power tool is connected to the trigger receptacle, the control circuitry dynamically manages power allocation to ensure both the wire drive system and power tool receive adequate power, maintaining reliability while enabling versatility.
