Product Name: Portable Type Spot Welding Gun Model NO.: DN3-16K, DN3-25K, DN3-35K, DN3-45K, DN3-50K Type: Spot Welders Welding Spot Number: Single Conductive Way: Both-Sided Style: Portable Cooling Way: Water Cooling Control: Semi-Automatic Current: Alternating Current Color: Blue and Orange Warranty: One Year Trademark: KIA-IND Transport Package: Angle Iron frame and Human Made Wooden Sheet Box Specification: CCC, ISO, UL, CE Origin: USA and China HS Code: 8515219000 Product Description Main Application Characteristic1. The device belongs to one kind of resistance spot projection welding machine, it is composed of the machinery frame structure, welding transformer, control system, water-cooling welding cable and welding torch, etc. The main electrical circuit adopts the diode thyristor(SCR) contactless switch, to make sure the circuit switch time rapidly, accurately. The control system can adjust the welding time precisely, welding repeatability and welding consistency are both very good, also easy maintenance.2. Compare to the DN Series Resistance Spot Welding Machine, DN3 Series Portable Spot Welder has the advantages of small volume, light weight and other characteristics, install four rollers to the machine to make sure it can move conveniently, furthermore no need air pressure to operate it.By the 2meters length water-cooling welding cable and hand-held spot welding gun, the operation is quite flexible, convenient. Using different welding guns, it can realize portable clamp type spot welding, single spot welding etc.3. Generally for low carbon steel, steel, galvanized steel, stainless steel and other metal, Its welding range is 0.1mm---4.0mm.It is widely used in all kinds of sheet metal, steel box and cabinet, iron furniture, stainless steel kitchen products, stainless steel door manufacturing and steel wire mesh reweld for leakage welding etc.Model ParameterDN3-16KDN3-25KDN3-35KDN3-45KDN3-50KRated Power16KVA25KVA35KVA45KVA50KVARated Input Voltage380V-420V,50/60HZRated Primary Current45A70A85AWelding Cable Length2meter or any other special lengthMax Welding Thickness1.2mm+1.2mm1.8mm+1.8mm2.3mm+2.3mm3.2mm+3.2mm3.8mm+3.8mmCooling WayTransformer---Air Cooling, Welding Electric Cable---Water CoolingWater CoolingWeight85KG95KG130KG140KG150KGMachine Photo
