Product Description

Hydrogen Oxygen Welding and Cutting Machine

 hydrogen oxygen welding and cutting machine is an energy equipment that decomposes hydrogen and oxygen from water by electrification. Hydrogen is used as fuel, and oxygen is used for combustion assistance. It can replace carbon containing gases such as acetylene, coal gas, liquefied petroleum gas(LPG) etc. It has the advantages of high calorific value, concentrated flame, zero pollution, environmental protection and cleanliness, high energy efficiency, easy operation, safety and reliability, cost-effectiveness, and good welding and cutting quality.

Specification

Applications
1.Steel cutting industry
2.Welding industry
 
 
Working principle of hydrogen oxygen welding and cutting machine
Add water and a small amount of electrolyte to the electrolytic cell to enhance conductivity. Connect two electrodes (anode and cathode) to a DC power supply. When the DC current passes, water molecules undergo ionization and electrode reactions under the action of an electric fieldpplications

Core reaction: Electrolysis of water

Total reaction equation:
2H2O → Electric energy 2H2 ↑+O2 ↑ 2H2 O Electric energy 2H2 ↑+O2 ↑
 
Electrode reaction:
Cathode (reduction reaction): 2H2O+2e − → H2 ↑+2OH − 2H2O+2e − → H2 ↑+2OH −
Anode (oxidation reaction): 4OH − → O2 ↑+2H2O+4e − 4OH − → O2 ↑+2H2O+4e −
