Use Method:
With oxygen acetylene flame on the workpiece is heated to 300-400℃
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
Different kinds of alloy powder used, can get the abrasion resistance, corrosion resistance and other different properties of strengthening layer

Attentions:
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
Spray gun, if no ignition, can not press powder valve switch, to avoid blockage
Due to the powder's particle size is not uniform, or become damp and other factors, make the powder valve switch failure, clogging, it should be repaired in time before be used again
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
Keep the gas pipeline drying, smooth to avoid damp effect of powder
All the pipelines of spray welding torch are not contaminated oil, to prevent oxygen meet oil to have combustion and explosion
Spray gun at the end of work, first close the acetylene valve, and then use the oxygen blowing internal pipeline, after liquidation shall be sprayed welding torch and hose hanging, prevent dust and impurity invasion of spray welding nozzle, to effect the normal use
The use of spray welding torch, oxygen, acetylene pipeline must be equipped with a backfire preventing device
