The purpose of this study is mainly for the oxygen - acetylene flaming combustion process to produce the effect of the combustion process problems. Its main forms in the combustion process is caused due to high temperature flamer tempered, once this happened is not achieve ideal result, welding is easy to make flame back to burn the dangers. Therefore a control device of the phenomenon is quite necessary.This is mainly due to the relatively high temperature flamer caused by such devices a jacket. Mainly in oxyacetylene cutting installed in the gun fire. This device is concise, outer wall and inner choose copper and iron welding formed by choice, outer wall hollow ferroalloy were used for welding of inlet and outlet water two ZuiZi. It forms a hollow internal cooling device, the coolant water.Through testing the device installed in flames shot after the fire after cutting temperature are obviously different. Install the device is not install the device than lower temperature burning, after. Through testing the device can be found after temperature control by gun fire, burning full, easy cause tempering. This device such as recognized by acetylene flame cutting to oxygen, the production process, the main advantage of low cost, easy to manufacture. But there may be confined to small-scale human production.Keywords: oxyacetylene cutting clamp
