Description

PRAKTIK TIG 202 DC PULSE DIGITAL is a professional inverter welding machine for TIG and TIG PULS welding, as well as MMA welding with direct current (DC) shielded electrode. 230V power supply. Welding current 5-200A.

PRAKTIK TIG 202 DC PULSE DIGITAL is a portable power source, made with IGBT technology, designed for TIG and TIG PULS welding, as well as MMA welding with direct current (DC) coated electrode. The small size and weight make the device ideal for both workshop and field work.

The device has three welding modes: TIG DC, TIG DC PULS, MMA.

TIG DC and TIG DC PULS function is used for welding stainless steel, carbon and low-alloy steels, copper and titanium. Welding is carried out in an inert gas shield.

By adjusting the parameters of TIG DC PULS pulse welding, we can influence the shape of the weld and the focus of the arc. Pulsed welding also reduces the amount of heat delivered to the material and is applicable when welding thin materials.

The arc is engaged in either non-contact (HF) or contact (LIFT) mode. The LIFT function is used when welding in environments with a high risk of being affected by electromagnetic interference to the environment.

With both HF non-contact ignition and LIFT touch ignition, we have the option to choose the function of the button on the TIG handle between 2-takt or 4-takt operation (button lock for long welds).

The easy-to-read and easy-to-use digital control panel allows accurate adjustment of the device, ensures stable parameters and high quality welding.

The digital display makes it easy to adjust the welder’s parameters:

• initial outflow of shielding gas
• inception current
• current rise time
• welding current
• base current
• current drop time
• residual current
• end discharge of shielding gas
• pulse length
• pulse rate

The welder also has functions to facilitate the process of MMA welding with covered electrode:
ARC FORCE: short-circuit current control – facilitates the transfer of molten electrode droplets to the material being welded, preventing the arc from being extinguished when the electrode droplet comes into contact with the welding pool

HOT START: hot start control – facilitates electrode ignition by providing more welding current each time the arc is struck.

ANTI STICK: anti-short-circuit – automatically shuts off the welding voltage if the electrode sticks to the material being welded, which makes it easier to peel off and prevents accidental welding arc.

VRD (Voltage Reduction Device) function – reduces the idle state resting voltage on the electrode to a safe value. Provides electric shock safety during operation in humid environments.

Physical parameters

The device has a fan-cooling system which dramatically increases its performance.

The quick-connect gas connection to the welding gun allows the welding gun to be connected and disconnected instantly without tools.

The device is equipped with overload protection, which increases its reliability.

Power supply parameters

Single-phase power supply 230V. The device is equipped with a power plug.

Equipment

The delivery includes a device with a set of TIG and MMA accessories: a TIG 17 welding chuck with a length of 4 meters, an MMA electrode cable with a length of 2m, a ground cable with a length of 1.5m.
