STAHLWERK AC/DC TIG 200 ST Digital fully equipped welding machine | combi welding machine | combi welding system | aluminum-compatible TIG MMA inverter with 200 A and integrated clean function

SKU: 1093
Category: TIG AC/DC Welding Machines

The STAHLWERK AC/DC TIG 200 ST Digital is a versatile 3-in-1 inverter welder with up to 200 A that combines TIG AC/DC, MMA/E-Hand and a special clean mode in one compact system. The modern IGBT technology ensures high energy efficiency, strong performance and very good welding properties at a low weight of just 12.7 kg. The combination device is therefore equally suitable for workshops, trades and ambitious users. It is operated via a logically structured digital control panel with display, which enables precise setting of all important parameters and improves clarity and handling. In addition to process selection (TIG, MMA, Clean) and AC/DC switching, four AC waveforms (square, triangle, trapezoid, sine) and extensive setting options are available, including gas forward and gas backward, start, welding and end current as well as current increase and decrease. Features include contactless HF ignition, 2T/4T operation, a spot function (especially for thin body parts, as reproducible tacking points with low heat input and less distortion are possible), a repeat function and a job memory with ten storage locations for reproducible results. Smart cooling, overheating protection and the robust ST-Guard housing support reliable continuous operation. The device also has a remote connection to operate the hosepack with WP26FR torch and offers finely adjustable AC frequency, AC balance and cleaning current for aluminum work to break up oxide layers and optimize the seam shape. The integrated Clean mode also enables electrochemical cleaning, passivation and finishing of stainless steel weld seams. The result is visually clean visible seams with a smooth surface and increased corrosion resistance. Such seams are required in apparatus and railing construction, for example. Three replacement carbon brushes and a screw adapter are included for long periods of use.

Functions

DC TIG welding - DC TIG for welding steel, stainless steel, copper, brass and many other metals. The infinitely adjustable welding current of 10-200 A enables sensitive adjustment to the material and sheet thickness.
AC TIG welding - AC TIG especially for aluminum and aluminum alloys. AC frequency, AC balance and cleaning current can be individually adjusted to optimally match penetration, seam shape and cleaning effect to the workpiece.
MMA/E manual welding - electrode welding with a current range of 30-160 A, suitable for many common stick electrodes. Hotstart facilitates ignition, anti-stick reduces the electrode sticking to the workpiece.
Clean mode - Special mode for electrochemical cleaning of stainless steel weld seams. Tarnish and oxide layers can be removed with a carbon fiber brush and suitable electrolyte; the current intensity is selected according to the degree of soiling and seam size. Three spare carbon brushes and a screw adapter are included in the scope of delivery.
HF ignition (TIG) - Contactless high-frequency ignition ensures convenient arc starting, protects the tungsten electrode and workpiece and makes it easier to work in hard-to-reach areas.
Job memory (0-9) - Up to ten complete parameter sets can be saved directly in the device and called up at the touch of a button - ideal for recurring jobs and different material/seam combinations.

2T/4T operation - either press and hold the button (4T) for long weld seams or press and hold the button (2T) for short seams; the start, welding and end current sequences can be controlled particularly conveniently. The device also has a remote connection for operating a WP26FR hosepack (not included in the scope of delivery).
Spot welding & repeat function - Spot mode for precise spot welding of thin sheets with pre-settable spot duration; repeat function enables recurring welding cycles without completely interrupting the current flow - ideal for uniform beads and serial work.
Flexible parameter setting - gas advance (0-2 s), current increase, welding current, current reduction (up to 25 s), final current and gas follow-up can be individually adjusted and allow precise control of the current curve and seam formation.
IGBT inverter technology - Modern high-performance electronics ensure a compact design, high energy efficiency and stable arcs with reduced power consumption.
Digital LED color display & logically structured control panel - All important parameters are clearly displayed and can be set quickly with just a few buttons and a central rotary control - ideal for daily use and recurring tasks.
Four AC waveforms - rectangular, triangular, trapezoidal and sine wave are available for selection and influence penetration, seam width and noise behavior. This allows the welding characteristics to be optimally adapted to the material and application.
Precise control of the welding curve - Adjustable start, welding and end current, current increase and decrease enable controlled seam run-outs and avoid end craters, especially with demanding TIG seams.
Smart cooling & ST-Guard housing - A powerful fan enables high duty cycles, while the robust ST-Guard housing ensures an ergonomic, reliable design and good protection of the components.
Compact dimensions & low weight - With 12.7 kg and housing dimensions of 449 × 238 × 437 mm, the device is easy to transport and is suitable for both stationary and mobile applications.

Note: The device is not intended for use in residential areas where power is supplied via a public low-voltage supply system. It may be difficult to ensure electromagnetic compatibility in these areas due to both conducted and radiated interference.
