Welding machine MT-4240 is designed for contact spot welding by alternating current of metal structures and products. Technological capabilities of this welding machine allow welding of a wide range of products. The thickness of the material to be welded depends on the material type and quality requirements to the welded joint. The welding machine provides the diameter of the cast core of the welded point which corresponds to branch instructions with the increased requirements for the quality of the welded joint.
Welding thickness ranges
|Low carbon steel||0,5+0,5 to 8,0+8,0 mm*|
|Low alloy steel||0,5+0,5 to 4.0+4,0 mm*|
|Stainless steel||0,3+0,3 to 4,0+4,0 mm*|
|Titanium alloys||0,5+0,5 to 4,0+4,0 mm*|
|Chromium-nickel alloys||0,5+0,5 to 2,0+2,0 mm*|
|Copper alloys||0,3+0,3 to 2,0+2,0 mm*|
|Aluminum alloys||0,5+0,5 to 1,5+1,5 mm*|
Diameter ranges for welded cruciform joints of rod reinforcement
|Class АI, BI||8+8 to 40+40 mm*|
|Class AII, AIII||8+8 to 35+36 mm*|
* When welding parts of different thicknesses, the welding mode is determined by the smallest thickness of the part.
Advantages of the welding machine МТ-4240
- It is produced of Russian raw materials that have all the necessary certificates
- Microprocessor control based on the contact welding regulator RKS-810, also produced by us, can store 20 welding programs in memory and consistently reproduce the welding parameters
- Setting of welding parameters on the front panel of the RKS-810 contact welding regulator and digital indication of the set parameters
- As a source of welding current we use a transformer, also produced by us, filled with epoxy compound
- Liquid cooling of the welding transformer, secondary circuit
- Independent regulation of welding and forging compressing force by two pressure regulators with counterpressure at pneumatic cylinder.
- Autonomous liquid closed cooling system
- Autonomous compressor device
- Electrodes for contact welding of various configurations
- Assembly and welding devices
