Always a clean weld on all workpieces !!!

The newly developed WIG TIG INVERTER series and welding equipment, allows you not only steel, but also un-and low-and high-alloy steels, nickel-based alloys, copper, and special materials and other ferrous metals with DC function (direct current) perfect to weld. (For aluminum the AC- alternating current function is required.) THIS DEVICE IS A PURE DC DEVICE (DIRECT CURRENT) 


With the system chip MOSFET (Toshiba) our devices have a high-performance technology that is proven since 1998. The Stahlwerk CT 520 PULS with TIG/MMA/Plasma includes the most advanced, innovative, easy-to-use quality engineering, so even beginners with the TIG welding process work easily. Compared to conventional welding equipment, the unique HF Inverter technology has many advantages. Smaller volume, reduced weight, continuously variable regulation, energy saving etc.. The application of inverter technology allows a focused and permanent power output. This made ​​an adjustment much more precise and practical. Our welder is working in a tube package with a ball joint and integrated switch. (Similar models work with cable ties)


Precision metering with TIG pulse function

The increased arc stability provides better welding precision. Thanks to this pulse functions, you can deeper weld in the workpiece (10 mm) without it ever gets too hot. A burn of the workpiece is prevented and a clean and stable weld is the result.


The pulse function is particularly suited for welding thin plates whose materials may be heated only slightly. Also thin sheets can be welded without burning. During the welding operation for a specified time (depending on the setting), the arc is uploaded with energy and automatically reduced.


Welding with comfort

You can use the STAHLWERK CT 520 PULS with TIG MMA PLASMA with a foot pedal, that will allow you a convenient and comfortable welding. The foot pedal and another accessory articles for TIG or plasma devices can be found in the Shop>>>

Function 1: DC TIG 200 A with PULSE function  

  • HF Ignition: high-frequency contactless ignition to the workpiece. 
  • Gas preliminary time: important to protect the weld from air supply and to create a gas atmosphere
  • Gas post flow time: saves the tungsten electrode against excessive wea. and protects the weld from oxidation.
  • Automatic slow current reduction after switching off the tube package. Adjustable between 0 - 10 seconds (makes a clean finish, there are no blowholes).
  • Welding with pulsing: penetrates deeper into the workpiece
  • Pulse frequency: adjustable between 0,5 - 200 Hz
  • Pulse current: adjustable from 10 - 200 A
  • Pulse range: adjustable from 10 % - 90 %


Only on this way you have a clean beginning and end of all welds.


The TIG welding is used for all fusion-weldable metals. In the TIG torch a tungsten electrode is used. It is needed, depending on the material, a welding filler material. In TIG welding the arc burns between a non-melt-tungsten electrode and the base metal. For the protection of tungsten electrode and melt, gases such as argon or helium or gas mixtures with non-oxidizing components are necessary.


Stahlwerk CT 520 PULS with TIG/MMA/Plasma welding equipment is particularly suitable when quality welds are extremely important. Private gardening - motorcycles, cars, trucks, classic cars, model making, stair  and balcony railings.- or in the professional and industrial sectors such as shipbuilding, aida, metal, metalwork, aircraft, garden, landscaping and welding schools , the highest quality requirements are met successfully with Stahlwerk welding equipment
This device is operated with DC (direct current).  You need to weld aluminum AC. We have in our shop also devices that can both AC and DC.
You can use the TIG Mode with a foot pedal, that will allow you a convenient and comfortable welding.


Function 2: Air Plasma CUT

The CUT 50  is for industry, crafts and private gardening optimally suited. In the last 8 years, more than 8,000 STAHLWERK  plasma devices were used in different work situations..Easy use, stability and accuracy guarantee a cutting at the highest level.

The professional plasma cutter combines the advanced TOSHIBA MOSFET inverter technology. By V - MOSFET technology, the device has a high duty cycle of 60%. For about 13 years, this technology is proven to the IGBT system Switch on the hand grip (similar models work with cable ties)


Cutting power up to 12 mm, depending on material:

  • Construction steel ST37 up to 12 mm
  • V2A up to 8 mm
  • Aluminium up to 7-8 mm


The device works at a high frequency ignition in contact with the workpiece, (advantage: more precise and faster cutting) With the CUT 50, you can easily cut all conductive metals such as standard steel, copper, stainless steel, brass, aluminum, titanium, etc. By the small deformation thin sheets can immediately be re-welded together An air compressor with at least 3.5 bar is required. (No more expensive gas).


Function 3:  Manual metal arc welding (MMA) with 200 amp: 

  • 60% Duty cycle at 200 Ampere !!!


MMA welding offers many advantages. The materials must not be preheated and can be directly welded to the desired positions. Workpieces of different thickness can be linked easily with each other. Thanks to the high temperature of the arc, even a 10 x 10 mm square steel can be welded with a 3 mm plate.Such constructions and compounds occur constantly in practice, for example as the construction of a railing, making a fence or in the repair of agricultural machinery. Often U-profiles are to be welded to thinner parts. MMA welding offer a wide range of applications in industry, craft, private gardening  and construction.


What types of electrodes can be used:

1) Unalloyed steels TYP R3, A5 und AR 7

2) For sheets up to 3 mm electrode R3 -  diameter 1,5 mm, 2,00mm, 2,5 mm.

3) For stronger materials electrode R3 - diameter 3,25 mm and 4,00 mm.

4) V-welds and pipes/tubes should be welded with electrodes A5 and AR7


  • Antistick: prevents annealing of the electrode (less consumable electrodes), because the power is immediately terminated.
  • Hot Start: automatic voltage increase at the start
  • Lift Ignition: in contact with the workpiece
  • Automatic cooling ventilators
  • MMA welding with rutile and basic coated electrodes for all un-and low-and high-alloy steels, nickel and copper alloys up to 4,2 mm


All these excellent welding features are a useful support for the use of this welding equipment. Perfect for beginners and advanced welders.  Even unskilled welders will immediately get good results with this device.
