Aotai Electric: a manufacturer of inverter equipment for welding and cutting
When it comes to industrial welding, cutting and solar inverters, few companies can show as solid a production base as Aotai Electric Co., LTD. Founded in 1993 by professors and their PhD students from Shandong University, the company is today one of the leading manufacturers of inverter welding and cutting equipment in China — with products that reach more than 128 countries around the world.
Who is behind the Aotai brand
Aotai is not just another anonymous manufacturer. The company was built by engineers with an academic background, which shows in its long-standing focus on research and development. The plant has a production area of almost 2.78 million square feet, 38 modern production lines, half of them fully automated, and a team of over 570 specialists in its R&D departments. The results of these investments are more than 320 patents and 4 in-house research centers.
This combination of academic roots and industrial scale explains why Aotai products are used in some of the most demanding sectors — automotive, shipbuilding, steel structures, heavy engineering, pipeline systems and emergency repair.
Product range: from welding machines to solar inverters
Aotai's portfolio covers nearly 100 models of welding equipment in 13 product series, including:
- Inverter MMA (SMAW) — manual arc welding with electrodes
- Inverter MIG/MAG (GMAW) — semi-automatic welding in a shielding gas
- Inverter TIG (GTAW) — precision welding with a tungsten electrode
- SAW machines — submerged arc welding for heavy industry
- Plasma cutters — for fast, clean metal cutting
- Laser welding — for high-precision industrial applications
- Accessories — water coolers, wire feeders, welding tractors, MIG/TIG torches, remote controllers
Beyond classic welding equipment, Aotai also invests heavily in automation and robotic welding — standard automated solutions, robotic cells and fume extraction systems (fume extractors) that meet today's requirements for productivity and occupational safety.
Since 2009 the company has also developed a separate solar business, producing grid-tied (on-grid) and hybrid inverters. The total installed capacity of its solar solutions already exceeds 10 GW — a figure showing that Aotai has long been more than a welding company: it is a complete supplier of energy and industrial solutions.
Why customers choose Aotai
Three words sum up the brand's philosophy: smart, stable, powerful equipment. Every product goes through more than 100 types of tests — mechanical, climatic, EMC and endurance tests — to guarantee reliable operation even in harsh industrial conditions.
The company also offers a full after-sales package: a technical response within 24 hours of an inquiry, fast delivery through a global distribution network and localized after-sales support in dozens of countries.
With over 30 years of experience, a solid production base and continuous investment in innovation, Aotai Electric has established itself as a reliable partner for companies looking for quality welding, cutting and automation equipment. The combination of engineering heritage, a wide product range and a global presence is making the brand increasingly recognizable on the Bulgarian industrial market too.
