Descript of STAHLWERK DC WIG 200 PULS S

power

TIG with 200 A.

MMA with 200 A.


Power adjustable between 10-200 A.


DC welding machine

For non-alloy and low-alloy steels, stainless steel, copper, brass etc.

Not for light metals such as Suitable for aluminum (no AC).


Gas cooled

Hose package gas-cooled.


ignition

Reproducible welding results through HF ignition (high-frequency ignition) and constant welding parameters at the start. The tungsten electrode does not touch the workpiece - this protects it and the seam is not exposed to tungsten influences.


Fully suitable for construction sites

High tolerance to network fluctuations ensures use in generator mode and with long supply lines up to 30 m. Construction site requirements IP23 and S marking are met.

The slim design and the low weight of the machine make it absolutely portable.

Inverter welder

The welding inverter is an electronic power source. Inverter welding machines are built for all arc welding processes such as electrode, MIG / MAG, TIG and plasma / TIG welding. The devices are switched on depending on the power or three-phase connected to the mains. The basic principle of an inverter corresponds to a switching power supply. The mains voltage is first rectified, chopped with the aid of power semiconductors with a frequency between 20 kHz and 150 kHz and transforms over a relatively small transformer to a lower voltage. Then the welding current by means of suitable diode must be rectified. The size of the same power transformers is approximately inversely proportional to its operating frequency, ie the transformer and the entire welding machine, the higher the frequency, the smaller and lighter can be built. The efficiency of inverter welding equipment is better than the other power sources. Due to the higher operating frequency strong dynamic welding processes can be much better controlled.


DC

DC - direct current (German: DC)

For non and low alloy steels, stainless steel, copper, brass, etc.

Not for light metals such as Aluminum suitable (no AC).


pulse

pulse power


Pulsed TIG is divided into two main areas:


Quick pulse (rapid pulse, RP)

- Frequency of 50 to 300 Hz

- Due to the strong current pulse a deep penetration ensures

- Due to the weak background current is easier to control the weld pool small and

- Low heat input

- Arc looks like the continuous tungsten inert welding

- Sound level is higher (due to the high pulse frequency)

- For thin plates (usually max 3.0 mm.)

- Especially good for materials with low thermal conductivity (iron, stainless steel)

- Improved welding speed as the continuous TIG

- Less deformation than the continuous TIG


Long pulse (Long Pulse, LP)

- Frequency of 0.5 to 1 Hz

- Two visually distinct periods, pulse and background

- Improved weld pool than in the continuous tungsten inert welding

- Differs from the position of welding

- Again weld filler wire addition during the pulse current, "drop by drop"

Technology

- Lower heat input than with continuous tungsten inert welding

- Weld with good visual appearance

- Improved welding speed as the continuous TIG

- Less deformation than the continuous TIG


Gas flow

Adjustable between 0 -. 2 s Protects the tungsten electrode against excessive wear and protects the weld from oxidation.


Gas tracking

Adjustable between 0 -. 10 s Protects the tungsten electrode against excessive wear and protects the weld from oxidation.


2T / 4T

In 2-stroke mode, the torch trigger must be kept pressed by the TIG hose package as soon as the button is released the arc is extinguished.

For 4-stroke remains after pressing and releasing the torch button the arc stable. Only by pressing the torch button the arc is extinguished.


Current drop

The current reduction prevents blowholes (end craters) at the end of the weld. After the torch trigger is released, the unit switches over to an automatic slow slope-. During this phase, the current from the set value for welding current is reduced to the circuit current. The duration of this phase can be adjusted from 0 to 10 seconds.


Anti stick

Shortly before the short circuit is the plant from the set maximum current, which prevents sticking and overheating of the electrode.


Hot start

Prevents short term by superposition of the set welding current, the sticking of the stable electrode and warms the weld start faster.


Remote control

By foot pedal (not included).


Safety: S mark and IP23

S-mark: for working in confined spaces with increased electrical hazard.

IP23: mandatory for works that take place outdoors.
