QH-2/h Metal Powder Spray Welding Torch,Oxygen Acetylene Flame Welding Gun

Description

Item specifics: The main components in one set: 1 3pcs welding nozzle , 2.The connecting nuts , 3 powder bucket seat 4 powder hopper 5 control powder feeder , 6 powder pressing hand 7 oxygen joint , 8 the acetylene joint , 9 the handle 10 acetylene handwheel , 11 in the middle of the subject 12 oxygen handwheel 13 hybrid junction 14 mixed gas pipe Metal powder spray welding gun: Use method 1st-step: with oxygen acetylene flame on the work piece is heated to 300--400 degrees Celsius. 2nd-step. 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 mutually cladding, dispersed to each other to form a binding layer firmly. 3rd-step: different kinds of alloy powder used, can get the abrasion resistance, corrosion resistance and other different properties of strengthened 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 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 . 4. attention --must use dry powder. 5. 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.
