LCS 06 control system brings uniquely sophisticated approach to functions including communication with the welding source.


This is a special solution which is provided only as custom made. Due to the complexity of the whole system and its parts very thorough consultation of requirements is always necessary. The final technical solution and possible feasibility of the project is provided as special project solution and always exactly based to the parameters of the required products, specific applications or the customer production program.



  • AWL 2050.25 LIFT is machine for longitudinal welding on copper base with double-sided holding of weldment with maximum length of 2050 mm and with controlled protection of the root of the weld with forming gas by the CascadeGas system. Central block of the machine is made of steel and supported by two ergonomically shaped supports. All electronic components and cooling system are located inside this block. The machine is designed for TIG AC/DC and Plasma AC/DC welding and is suitable for welding of alloy and non-alloy steel, CrNi steel, copper, aluminum, titanium and other materials such as galvanized steel and aluminized steel.

  • The construction of the machine's force arms is designed as steel welded half-shell spatial costruction which is characterized by controlled flexibility thanks to the unique design of elasticity. Both arms are fixed to the central block which fixes the welding thorn. Left arm carries the linear guide of the torch head. The pressure of the weldment against the welding thorn is realized pneumatically via gear levers with transversely adjustable segments made of high-quality CuCrZr alloy (as custom made solution the machine can be equipped with pressure segments from stainless steel whichs are necessary for example for welding of aluminum for better cooling after welding).
  • Central block is located on spatially welded robust construction in which the control electronics are located. Through the hydraulic lifting mechanism the maximum diameter of the weldment can be reached up to 2500 mm. The hydraulic lifting mechanism is carried on linear linings on robust central column with two stabilizing supports and hydraulic cylinder with stroke length of 1490mm. The stroke is controlled electronically on the machine's control panel.
  • During designing of machine we also solved problem of suction of welding fumes by integrating the suction channel directly into the construction without negative effect on welding process which is advantagous especially when welding galvanized materials. The connection of this device is solved by pipe with diameter of 100 mm.
  • Part of the construction are sufficiently dimensioned steel gangways for comfortable operation of the machine even in the case of welding bigger diameters when the base of the machine is raised. These gangways are firmly connected to the base of the machine so they rise smoothly together with the machine and are equipped with safety railing to ensure the operator against falling.
  • Welding thorn is made of low-alloy steel with high flexural strength. Uniquely designed precisely machined CuCrZr alloy basis bar internally cooled by liquid is mounted on the welding thorn in which CascadeGas system for saving shielding gas while protecting the root of the weld is also integrated. Basis bar can be also made from stainless steel as custom made solution for welding of aluminum.
  • Gas management is divided into three independent ways - torch way, after-cooling way of the weld track and the forming gas way. Forming gas way uses our unique CascadeGas system. Set of valves switches forming gas so the gas protects the root of the weld only in necessary length depending on current position of welding torch. According to position of welding torch CascadeGas system automatically divides the forming gas into each sections. As result the consumption of forming gas is significantly reduced up to 80%. All gas ways are equipped with precise flow meters and valves that precisely control gas flow.
  • Torch head is equipped with pneumatically controlled torch holder which is parked in horizontal position to facilitate visual checking of condition of each parts of the torch. Longitudinal movement of the torch head is done with backlash-free drive system of servomotor, planetary gearbox and belt drive. The positioning of the torch has repeatable accuracy of 0,2 mm and welding speed from 10 cm/min to 300 cm/min, rapid traverse is 600 cm/min.
  • Machine can be equipped with a cold wire feeder HST CREATIVE CW 07. The cold wire feeder is fully controlled by the LCS06 control system and brings to the operator the maximum possibilities of setting of the feeding parameters including the reversation of the feeding of the wire.
  • Machine is controlled by LCS 06 control system which has been designed especially for linear welding automats. The system has a wide range of sophisticated functions by which all the requirements of linear welding are solved. LCS06 controls the whole spectrum of interesting and sophisticated functions including UP/DOWN logic.

Supporting functions

  • Confirmation of  a welding arch. LSC 6 waits for the signal from the welding machine, when the signal is received  a program begins to use set working cycle. This is a fundamental function for welding of thin materials, especially aluminium welding. This function also eliminates unreliable ignitions.

  • Controlling system. High technical level of this product is emphasized by controlling system, which check correct settings and also block the machine in case of functional or user mistake. All faults are namely displayed and indicated by LED "Incomplete".

  • AR function. Very unique AR function allowing to weld metal plates, which are not cut straight, without switching or rotating the material. This function is very substantial in practice, because it is able to weld inaccurately cut plates with productivity, which the same machine without this function can never achieve.

  • Mid-product welding function. It allows to weld from the middle to the right, then the torch returns to the middle at the place already welded and then makes a weld to the left. This function is suitable for welding of thick materials, when the tubes are extremely inaccurate.
