Frequently asked questions
How is metal cut underwater by divers?
Is specialized training required to use this tool?
Yes. Employers must provide operator training before allowing their personnel to do any oxy-arc underwater cutting. Oxy-arc cutting is potentially dangerous due to the nature of incorporating 100% oxygen and high electrical amperage together. Additionally, hydrogen gas is produced in the cutting process. Users must be properly trained and strictly follow all safety procedures according to manufactures and industry accepted safe diving practices as found in the Association of Diving Contractors International "Consensus Standards for Commercial Diving" and adhere to ANSI Z49.1:2012 "Safety in Welding and Cutting" standards and OSHA Safety and Health Standards "29 CFR 1910.
Can material other than steel be cut underwater with this tool?
Yes! There are two types of electrodes (rods) that are commonly used, exothermic and tubular. When ignited, the exothermic electrodes burn at 8000 to 10,000 degrees fahrenheit. Exothermic rods can be used to cut rock, concrete, wood, cast iron, stainless steel and non-ferrous metals.
Can Oxy-arc cutting be conducted using SCUBA gear?
Can Commercial Diving Technologies (CDT) provide expert training in the safe and efficient use of oxy-arc cutting?
