Digital Controlled Inverter Drawn

Arc Stud Welding Machine

Sino Stone Industrial Limited

1• Time-saving and cost-saving. Unnecessary to drill holes, punch holes, threading, riveting or screw

thread. The installation of stud in workpiece surface can be completed within several seconds.

2• Wide application range. Suitable for the welding of stud in diameter 3~25mm, and workpiece in

thickness over 1mm.

3• Little distortion of workpiece. No repairing process.

4• High intensity of welding joint, equal to or surpass the intensity of base metal.

5• After the welding completeness in coated metal or high-alloy metal, there is no marks left on back

side.

6• High welding efficiency. Usually, six studs can be welded per minute at least.

7• Low investment on materials and equipment.

Advantages of stud welding

1• It is sensitive about the carbon amount in steel.

2

• For structural steel stud, the carbon amount should be limited within 0.18%, and the carbon amount in base metal should be within 0.20%, or stud and workpiece can not be melted together.

3• It is difficult to operate in narrow space.

• The IGBT soft switch inverter technology is adopted,

the wearing of switches can be highly reduced,

electromagnetic interference is also reduced, then

confirm the stability of the machine.

Soft Switch Inverter Technology

Full bridge soft switch inverter circuit

Double IGBT moudule

Heavy duty cycle

• In case of welding defects on studs, there is a

stick welding function to use.

• Adaptive capacity of wide distribute voltage

– The input voltage range is 3 phase 380V(±15%)

50/60Hz.

– When the distribute voltage fluctuate in 323V~437V,

the input voltage can be adjusted automatically and

have no affects for welding.

Stick Welding Function

• The world top brands of components are chosen

to confirm the machine quality
