STAHLWERK DC TIG 200 Pulse ST, Inverter welding machine with 200 amp TIG & MMA

  
Machine is very lightly used and has been replaced by an AC/DC inverter welder. Welding of almost all materials such as steel, stainless steel, copper, brass and many more. 2 in 1 combined device. TIG and MMA welding up to 200A.

TIG PULSE - Prevents the burning of materials and reduces deformation due to heat, particularly suitable for welding thin plates, the material of which may be heated only slightly. Basic current, peak current, pulse frequency, long and short pulse. Determines the control of the operating mode and provides extended control over the current flow. In 2T mode, high-frequency ignition (HF) remains active until the button on the torch is released. In 4T mode the arc is ignited after a single press and release of the button.

After pressing and releasing again, the ignition is stopped. Prevents voids (end craters) at the end of the weld. Protects the tungsten electrode against excessive wear and protects the weld from oxidation. The parameter can be set individually and separately. It indicates how long after ignition ends gas should flow.

Latest transistor technology enables highest power and a duty cycle of 60% at full power. No transformer, no MOSFET, modern IGBT. 455 x 220 x 275 mm. Innovative IGBT transistors save space and weight compared to the old MOSFET technology. Allows non-contact ignition and ensures a much better welding result. Welding current / Basic current. The two rotary knobs welding current and basic current, two different current intensities can be set for a welding operation between which the welding current always changes. The pulse frequency determines how often the current changed back and forth between the two set values within a fixed time interval. The weld becomes wider, the heat input is higher and the penetration is deeper.

The weld pool is easier to control and the danger of welding a hole in the sheet is lower. Remote controllable current control via foot pedal. The foot control mode gives you the advantage that you can control the current even during the welding process, which gives you various possibilities for the execution of the welding work.

The maximum current is set on the device. The foot pedal is set to 10. When the foot pedal is pressed, the device ignites with a lower current than indicated on the display.

Once the foot pedal is fully depressed, you reach the set maximum current. The value on the display does not change during this time.

Examples: - Maximum current display: 100A / ignition current by pedal: approx. 40A - Maximum current display: 150A / ignition current by pedal: approx.

80A - Maximum current display: 200A / ignition current by pedal: approx. Automatic voltage increase upon the start for better ignition results. Anti-stick - Automatic shutdown of the welding current in case of sticking of the electrode which allows an easy removal.

It also prevents annealing of the electrode. Inert gas welding with inert / inactive gases such as Argon 4.6 (99.996%).

An arc is created in an argon bell between the tungsten electrode and the workpiece. This melts the material and any filler material that is supplied. A weld seam is created. MMA / Stick electrode welding. Is a universal welding process.

No protective gas is needed. The item "STAHLWERK DC TIG 200 Pulse ST, Inverter welding machine with 200 amp TIG & MMA" is in sale since Thursday, December 9, 2021.
