Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply apparatuses for welding machines require cumbersome and time-consuming operations for selecting and setting welding modes and parameters, making preparation and switching between different welding conditions inconvenient and costly.
Innovation Solution
A power supply apparatus with a control panel unit for setting welding conditions and memory means to store and recall these settings, allowing for simplified mode selection and parameter setting, including automatic setting of currents and time periods based on peak current settings, and the ability to store and retrieve previously used welding conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple power supply apparatuses are provided for different welding modes, then welding adaptability is improved, but cost and operational complexity increase
Solution Approach 1:
The power supply apparatus is designed with a single unit that can perform multiple welding functions (manual welding, DC TIG welding, AC TIG welding) by storing different welding conditions in memory means. The control panel unit allows selection between different welding modes, and the memory means retains the set conditions for each mode, enabling one apparatus to replace multiple specialized apparatuses.
2Manufacturing precision
If welding parameters are manually set for each welding mode, then welding precision is improved, but operational time and complexity increase
Solution Approach 1:
The memory means stores pre-set welding conditions for different welding modes in advance. When a welding mode is selected, the corresponding pre-stored conditions are automatically read out and applied, eliminating the need for manual re-setting of parameters each time. This preliminary storage of welding conditions significantly reduces preparation time while maintaining precise parameter control.
3Device complexity
If welding conditions are not stored in memory, then device simplicity is improved, but operational convenience deteriorates
Solution Approach 1:
The memory means creates and stores copies of welding conditions for different modes. Instead of requiring complex real-time calculations or manual re-adjustment, the system stores duplicate sets of optimized parameters for each welding mode and simply retrieves the appropriate copy when needed. This approach maintains operational simplicity while dramatically improving ease of switching between modes.

AI summary
Welding conditions are set for a power supply apparatus for use with a welding machine, using a control panel unit (96). A memory (105) stores therein welding conditions as set through the control unit (96), and holds the set welding conditions after turning off of a main power supply switch (1) of the power supply apparatus. Upon turning on of the main power switch (1) for starting welding, the welding conditions stored and held in the memory (105) are read out and set in the power supply apparatus.
