Daiwa Thermic Lance


DAIWA THERMIC LANCE  (TL) is steel pipe filled with wires or a mixture of wires and an inner pipe, when burning generates powerful flame  up to 4,000°C without noise and vibration to break up materials quickly. This product is mainly used for burning and cutting large iron castings, stainless steels, brass, non-ferrous metal, refractory materials, concrete, ceramic, natural stone, etc... with high efficiency and productivity.

A super burning for heavy gage scrap cutting

Thermic Lance is steel tube that to be used for fusing the metals and so on. The principle is that harness the oxidation heat of high temperature by provided the pressurized oxygen to inside ignited steel tube. Generally inside of metal tube contains steel wire that promotes the combustion.

Connection Setting

By using Threaded Socket to connect two thermic lances together. Another way for connection is to use Quick Coupling to connect two thermic lances together. This is a simple and easy way without any tool is requied.
1. Wear the protective equipment of provision correctly. 
2. Above Fig. was shown the connection example of equipments.
3. The pressure of oxygen should be 8-12bar by oxygen regulator.
4. Make sure that there are no leaks from hose, coupling and joint.

Products Specification

Type of Daiwa TH Lance

Type Description
T Type T with a mixture of wires and an inner pipe produces a straight flame at high speed that can splash out, make holes or break up materials quickly. The materials suitable for Type T are carbon steel, iron, slag, copper, aluminium, brass, etc.
W Type W with a fully pack of wires produces a wider flame at higher temperature than Type T. Its distinct feature is to dissolve solid materials that have high melting points such as stainless steel, nickel, concrete, refractory materials, nature stone, etc.
