The power sources for TIG and MMA welding MASTROTIG line are the top of the Deca range, ideal for maintenance, repair and construction work. They meet professional  needs and are guaranteed by the LAB mark of excellence. Carefully designed and manufactured at our San Marino factories.

All models have unique features both of operation and construction: excellent ignition, power and arc stability, an extremely easy and clear professional control panel. Possibility to act on all welding parameters both in manual mode and using the EASY PULSE and AC EASY welding aids, body in light aluminum alloy.

The great flexibility of the welding machine is supported by the possibility of saving some “user welding point” in internal storage memory.

Three models are available: MASTROTIG 218 DC LAB Pulsed single phase, MASTROTIG 216 AC/DC LAB Pulsed single phase and MASTROTIG 327 AC/DC LAB Pulsed three phase.

The MASTROTIG 216 AC/DC LAB model delivers 160 Amps in TIG (DC & AC wave form) and 130 Amps in MMA mode.

It is designed to weld with the TIG process both in normal mode and in the more sophisticated PULSED TIG mode. It also welds with rutile and basic coated electrodes.

Some of the main TIG features:

• TIG HF LIFT: arc striking occurs without touching the piece by means of the high frequency or by touching the piece with the electrode and slowly lifting it. The risk of contaminating the piece with the tungsten electrode is low.
• Setting the diameter of the TIG electrode: to guide in subsequent adjustments.
• TIG pulse: manual adjustment of frequency and base current.
• Easy pulse: the TIG pulse is used to obtain a good penetration without heating the piece too much. The system automatically adjusts the current reduction to the most appropriate pulsation frequency based on the welding current set: no special knowledge is required.
• AC Frequency adjustment and balance: manual in TIG welding in alternating current.
• AC Easy: an internal synergy in the microcontroller takes care of better managing the frequency and balance of the alternating wave when welding in alternating current, for example on aluminum or stainless steel of low thickness.
• Bilevel welding: selection of two welding currents (high and low) by pressing the torch trigger. Useful for special jobs when a pedal is not available.
• Adjustable Pre gas / Post gas: to avoid contamination of the weld pool.
• Adjustable Slope Up / Slope down: progressive increase and subsequent decrease of the welding current to obtain a flawless beginning and end of the welding seam.
• 2T/4T: allows you to weld without having to keep pressing the trigger of the torch.
• Spot: to obtain welding points that are all the same (riveting).
