This welder is an inverter based machine the utilizes the most advanced inverter technology. IGBT circuits along with PWM
technology along with the greatly reduced size and weight, enable this welder to not only be more efficient by 30%, but also as a
result of the electronic circuitry, enables this welding machine to afford the user far more and better range of settings for each
specific weld. The ACDCTIG200 also has a 40% duty cycle at full amperage which, explained another way, allows for a full four
minutes of uninterrupted continuous welding at full amperage within a ten minute period. Far more capable than any user
would dream of attempting.
The ACDCTIG200 is capable of welding with either AC or DC current. This allows the user to choose DC current welding for
carbon steel, stainless steel, copper and many other metals, while also being equipped with the ability to switch over to AC
welding used in welding aluminum and aluminum alloys. In addition to its advanced TIG welding functions, the ACDCTIG200 is
also a very good MMA / Stick welder.
This AC/DC TIG welder adopts our company’s exclusive High Frequency technology as well as a pure square wave output,
excellent arc force and a wide range of balance control for aluminum cleaning.
This AC/DC TIG welder also offers a feature not always found in this price range. That is a completely dedicated foot control
with no interim current control on the foot pedal. This design is a much sought after feature of advanced welders who dislike
greatly the idea of inadvertently changing amperage settings while readjusting the foot pedal with their feet while changing their
welding positions. This is no longer a concern with the Weldpro ACDCTIG200 since all amperage control settings are made
from the console on the machines face.
Thank you for purchasing our product. We are sure you will soon realize the great value and quality that went into the design of
this welder as well as all of the advanced features and functions.
