Changzhou Welding Technology Development Co., Ltd.

CWTD stud welding unit is controlled by a micro-computer, which joins

studs with base-material immediately by arc initiated through energy

discharging of capacities. It has features as follow:

Short welding time, arc time about 3-6ms, high efficiency, 16-20 studs could be

welded in one minute.

There is no bead, no welding trace, no color changing, less deformation in the

face of workpiece and no damage to the painting, Zn cladding or plastic coating on

back face of workpiece.

The strength of weldment is the same high as that of base-materials and studs.

Operating convenience, welding can be carried out just on one side of

work-piece.

Need not drill hole, no leak possible.

Can be used to weld carbon steel, stainless steel, copper and copper alloys,

aluminum and aluminum alloys and dissimilar metals.

The discharging voltage is monitored precisely.

The operation is interlock to avoid secondly trigger after a welding cycle.

Stepless adjusting setting voltage.

Self-diagnosis helpful for troubleshoot.

LED display for easy read.

Compact design.

CWTD welding unit can be used in locomotive and rolling stock industry,

automobile manufacturing, shipping building, chemical industry, electric and

electronic manufacturing, instrument industry, kitchen articles and metal household

manufacturing and construction metal wall industry. It is suitable for varies metal

studs’ welding, as shown in table 1.
