Use method :
1. With oxygen acetylene flame on the workpiece is heated to 300--400 degrees celsius.
2.The nozzle and the workpiece surface distance 120~150 mm, at same time you can put the self fluxing alloy powder evenly sprayed on the surface of the workpiece, and then through the flame to melt, to appear on the surface mirror, gradually Moving molten position, so that the alloy powder and the workpieces polarized, dispersed to each other to form a binding layer
3.Different kinds of alloy powder used, can get the abrasion resistance, corrosion resistance and other different properties of strengthening layer.

Note:
1. Medium pressure type structure, it must be used in the medium pressure acetylene generator and an acetylene cylinder pipe, absolutely should not be used in low pressure acetylene generator and pipeline.
2. Spray gun, if no ignition, can not press powder valve switch, to avoid blockage.
3. Attention --must use dry powder.
4. Regular cleaning spray gun, in order to avoid the gas tube holes are blocked. while cleaning pipe hole ,ejects out and clean up the control powder feeder.
5. Keep the gas pipeline drying, smooth to avoid damp effect of powder.
6. All the pipelines of spray welding torch are not contaminated oil, to prevent oxygen meet oil to have combustion and explosion .
7. The use of spray welding torch, oxygen, acetylene pipeline must be equipped with a backfire preventing device.
