At the trade Show last year in Melbourne, we ha the opportunity to show the Ocean Liberator to our Australian Manufacturers. coping or Notching, as referred to by some customers, has long been a laborious job which required huge investments to automate. The Ocean Liberator is a different Story. Low Cost Oxy Fuel, with no need for expensive Dust filtration units is easy to operate, and as you can see from the pictures, provides a very clean finish. Our Technician, Nick, and the Oceanettes were very happy in demonstrating the ease and efficiency of Coping and Notching Steel with the ocean Liberator.
