This top-class device sets new standards among DC welding machines, and the user-friendly control panel ensures selection of all necessary operating parameters.

The MEGA TIG 400GC welding machine enables welding using the following methods:

• TIG DC PULSE lift-arc - arc ignition occurs through contact of the electrode with the welded material; the pulse function allows welding of thin elements through periodic changes in current intensity.

• TIG DC PULSE HF - non-contact HF ignition using an ionizer in TIG DC PULSE mode

• TIG DC lift-arc - In the TIG method (Tungsten Inert Gas), the electric arc is ignited in an inert gas shield (argon), between the welded element and a non-consumable electrode made of pure tungsten or tungsten with additives. In TIG lift-arc mode, arc ignition occurs when the electrode touches the welded element. In TIG DC mode, the current is constant.

• TIG DC HF - In order to completely eliminate the possibility of contaminating the weld with tungsten, it is recommended that the electrode does not touch the welded element; for this purpose, non-contact arc ignition is used by means of high-frequency discharges generated by the ionizer built into the device.

• MMA DC+ - In the MMA method, a coated electrode is used, consisting of a metal core covered with flux coating. An electric arc is generated between the end of the electrode and the welded material. Arc ignition occurs by touching the electrode tip to the welded material. MMA DC+ means welding with positive polarity – more heat is generated in the material and less in the electrode.

• MMA DC- - the difference compared to MMA DC+ is that the polarity in MMA DC- mode is negative, therefore the heat distribution is reversed – more heat is generated on the electrode and less in the welded material.

• MMA VRD DC+ - the VRD (Voltage Reduction Device – module reducing the idle (no-load) voltage of the device’s secondary circuit) function available in MMA DC+ mode. It increases safety and reduces the risk of electric shock. The function switches the welding power supply off and on when resistance between the electrode tip and the welded element is detected during welding.

• MMA VRD DC- - the VRD (Voltage Reduction Device) function available in MMA DC- mode operates analogously to MMA VRD DC+, the difference being negative polarity.

For all TIG methods, the following welding modes are available:

• ARC IGNITION VIA LIFT-ARC SYSTEM (2T and 4T)
• NON-CONTACT HF ARC IGNITION (2T and 4T)
• ARC IGNITION WITH REMOTE CONTROL PEDAL (2T and 4T)

DEVICE FEATURES:

• compact design,
• high efficiency 60%,
• easy-to-use control panel,
• 2-STROKE and 4-STROKE,
• HF or LIFT mode,
• dual-function adjust knob (coarse and fine adjustment),
• possibility of connecting remote control - control pedal, torch with potentiometer
• very wide selection of welding functions:
  • HOT START - function increasing the current at arc ignition, facilitating the start of welding.
  • HF - the device is equipped with an ionizer that enables non-contact arc ignition.
  • PRE and POST GAS - gas flow before and after welding.
  • UP and DOWN SLOPE - rise and fall of welding current.
  • PULSE - pulsed current function, mainly used for welding thin elements (even with a thickness of 0.1 mm), metals with a low melting point such as lead, or welding in forced positions. Other advantages of pulsed current welding include a smaller heat-affected zone, greater arc stability, greater penetration depth, and improved weld face appearance.
  • ARC FORCE - function stabilizing the welding process by maintaining the welding arc voltage value regardless of its length and facilitating control over the amount of spatter.
  • VRD - Voltage Reduction Device - reduces the no-load voltage of the device’s secondary circuit. Increases safety and reduces the risk of electric shock.
  • PFC - Power Factor Correction - increasing the power factor to a value as close as possible to 100% in order to reduce power losses in transmission lines.
