Machines for processing of wire and rebar
Automatic Welding Machine WPA series

Automatic multi spot welding machine WPA series has a line wire coils and cross bars feeder, improved performance about 6.5 tons per shift. WPA series machine is designed for mass regular mesh production of various diameter for sale and construction industry. WPA series require more space for full production cycle in comparison with compact WP series.

How it works

Operator sets up the desired technical parameters via control panel, and makes general adjustments of the machine before welding. Automatic machine requires line wire from coils. line wires are inserted through the pre-straightening roller blocks and collet mechanism.  The collet mechanism moves the line wires to the welding unit. Using straightening and cutting machine the operator prepare appropriate size cross bars in advance. The cross bars are loaded to bunker. Feeder throws off the cross bars one-by-one from the bunker into welding zone automatically. Multi spot welding in place of intersections is performed cascaded.

Basic features 

WPA series combines the advantages of WP and WL machines. WPA welding unit based on several pairs of electrodes (heads) that allow changing the pitch dimensions of the line bars without changeover welding busbar system. WPA machine is the best solution to save up to 15% costs when the production output depends on regular mesh various diameter of wire.

Pre-straightening unit

Preliminary straightening of line wire is performed in two dimensions by rollers system installed in the units. Each unit is customized for appropriate line wire individually. The system is equipped by collet feeders of the line wire and allows the welding of specified pitch dimensions precisely. 

Mesh scissors 

Specially made for cross cutting of the mesh of a specified length. Configuration of the positions is made via control panel. The scissors are pneumatic driven.

Packaging unit 

Packaging unit removes the welded mesh from the welding machine. The ready panels drop off in a stack when the welding is complete. If necessary, the unit can be equipped with manipulator, and turn over every second mesh.
