Introduction oxyhydrogen welding with oldest oxy-acetylene welding

Introduction the difference between newest welding process oxyhydrogen welding and oxy-acetylene welding
Oxy-acetylene as known as oxy-fuel,is one of oldest welding processes.The main different feature between oxyhydrogen welding and oxy-acetylene welding is if there is necessary for gas cylinders.The newest welding and brazing is oxyhydrogen welding which featured no gas bottles and hho gas production once machine power on.Therefore,oxyhydrogen welding and cutting is absolute safety compared with oxy-fuel welding and cutting.
