The biggest advantage of this model is the full functionality of TIG welding with both direct current (DC) and alternating current (AC). DC mode is ideal for precision joining of stainless steel, black steel, copper and titanium, while AC mode is essential for welding aluminum and its alloys. The device offers advanced AC parameter control, including AC balance adjustment (the ratio between cleaning and penetration, crucial for aluminum) and AC frequency adjustment (affecting arc focus and stability). What’s more, a Pulse function is available for both DC and AC current. DC TIG Pulse helps control heat in thin steels, while AC TIG Pulse makes it easier to weld thin aluminum and improves pond control. Two arc ignition modes are available: non-contact HF and contact Lift-TIG. This versatility makes the Focus TIG 200 AC/DC PFC a complete TIG tool, ready to tackle virtually any task in the current range up to 200A.

The Focus TIG 200 AC/DC PFC is not only an advanced TIG, but also a very good MMA (shielded electrode) welder with a maximum current of 180A. This allows efficient welding with most popular rutile, alkaline or stainless steel electrodes with diameters up to 4.0 mm. Like the DC HP version, this model is equipped with Hot Start functions for easy ignition and Arc Force for arc stabilization and sticking prevention. The high idle voltage (about 95V) further facilitates arc initiation. A very good duty cycle in MMA mode (140A @ 100%) enables comfortable operation even on more demanding tasks. For the professional working in the field, the ability to quickly switch from precision TIG welding to fast and versatile MMA welding with the same lightweight device is extremely practical and saves time and space. This is a truly multi-tasking welder.

Whether you’re welding TIG AC, DC or MMA, the built-in PFC (Power Factor Correction) circuit ensures optimal use of power from the 230V mains. It reduces power consumption compared to units without PFC, which lowers operating costs. More importantly for professional applications, the PFC stabilizes the welder’s operation during voltage fluctuations (tolerance of -40% to +10%) and allows seamless power supply from long extension cables (up to 100m) without significant power loss. It also allows for cooperation with generators with less power than traditional equipment would require. For the welder, this means greater reliability and stability in a variety of often difficult power supply conditions, which is key to maintaining quality and continuity of work at the assembly or in the field.

The Focus TIG 200 AC/DC PFC retains all the mobility advantages of the Focus series. With a weight of about 13.5 kg and compact dimensions, it is one of the lightest and most compact professional TIG AC/DC welders on the market. The convenient transport handle and included shoulder strap make moving the unit between workstations, floors of a building or transporting it in a car no problem at all. This exceptional mobility is invaluable for service technicians, installers, repair companies and all professionals who need to be flexible and often work outside of a permanent workshop. The Focus TIG 200 AC/DC PFC proves that advanced all-metal TIG welding technology can be available in an exceptionally handy and easily transportable form.

The control panel of this model is designed to provide easy access to all the necessary TIG AC/DC and MMA functions, despite their sophistication. The easy-to-read digital display accurately shows the set current values, as well as additional parameters. Using ergonomic buttons and a dial, you can easily select the welding method (TIG HF AC/DC, TIG Lift AC/DC, MMA), activate the Pulse function and adjust its basic parameters. Importantly for aluminum welding, the panel allows precise adjustment of AC Balance (affecting cleaning/penetration) and AC Frequency (affecting arc focusing). Adjustment of gas discharge times (pre-gas, post-gas) is also available. Despite the wealth of features, navigation through the panel is logical and intuitive, allowing the welder to quickly adjust the parameters to suit the specific task and material.

Like all Migatronic professional devices, the Focus TIG 200 AC/DC PFC features a robust and thoughtful design. The robust housing protects the delicate inverter electronics from mechanical damage in harsh working conditions. The IP23S degree of protection guarantees resistance to dust, moisture and allows safe operation even in adverse weather conditions (with caution). The use of high-quality components and efficient cooling translate into reliability and long life of the device. Despite its light weight, this is equipment built for intensive, professional use that will not fail at crucial moments. It’s an investment in durability and reliability for years to come.
