供应手持式点焊机 焊钳式点焊机 便携式点焊机 可移动式点焊机

DN3系列手持式点焊机
DN3 Series Portable Spot Welding Machine
设备主要特点
1.该设备属于电阻点凸焊机的一种，由机架结构，焊接变压器，控制系统，水冷焊接电缆，点焊焊枪等几部分组成。电气主回路采用二极管可控硅无触点开关，电路开关时间迅速，准确。焊接时间可通过控制系统精准调节，焊接重复性与一致性好，维护方便。

2.相对于DN系列电阻点凸焊机，具有体积小，重量轻，等特点，焊机、焊枪都可移动,在结构上破除了老式焊机的固定电极臂旧模式。机器下面配有四个滚轮，移动方便，同时使用时不需要气压，配有2米长的通水焊接电缆及手持式点焊枪，操作起来特别灵活，方便，选用不同的焊钳，可以实现手提式钳式点焊，单面单点点焊等功能。

3.焊接范围一般为0.1mm---4.0mm的低碳钢，碳钢，镀锌板，不锈钢等多种金属，广泛应用于各种板金，箱体，柜体，铁质家具，不锈钢厨房制品，不锈钢门业制造及铁丝钢丝网片漏焊之后的重新补焊等的焊接。

Main Application Characteristic
1.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.
pare 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.
