YQY-220 series of movable oxyhydrogen welders are ideal products to replace oxygen-acetylene welders. They have advantages of effective, energy-saving, non-polluting, safe, vast capability, etc. Basic working principle: take water as the material, electrolyze water to have hydrogen and oxygen, and then emblaze hydrogen and oxygen to gain flame in high temperature, to start welding and cutting. Oxyhydrogen welders can weld black metals, color metal boards, tube materials and other melting materials.

Movable oxyhydrogen welding and cutting machine compared with other welders has the following characteristics:

1.Notable economic benefit: low cost (if compared to traditional acetylene, the cost is decreased by over 50%). This machine only need to add electrolyte (10% of potassium hydroxide) for the first time to start the machine, and for later common uses, you only need to add ordinary tap water (distilled water or purified water will be better).

2.Nonpolluting: the working principle is: electrolyze water to have hydrogen and oxygen, and then emblaze hydrogen and oxygen to gain flame in high temperature. In this process, no venomous object comes into being.

3.Safety: this machine has circuit automatic protection system, temperature control protection system, backfire defending protection system, pressure control protection system, to make sure of safe working.

4.Vast application: Oxyhydrogen welders can weld black metals, color metal boards, tube materials and other melting materials.

5.Vast capability: they can be used in any place with power source (220V±10%).

6.Convenient operation: this machine has automatic controlling system. If the worker owns acetylene technology, then he can use the machine just through short-time familiarity.

7.Strong working continuity: this machine can work continuously for quite long time (continuously work for 120 hours, without any fault).

8.Conveniently movable: the machine can move conveniently, applicable for those welding and cutting tasks that need move often.
