SQUARE WAVE TIG 250 AC/DC TIG/STICK WELDER

1. AC/DC TIG/STICK welding
2. Square Wave Technology
3. Post-flow Setting
4. Remote Foot Control
5. Digital Display
FEATURES AND BENEFITS
* Multi-function: AC/DC TIG/STICK welding
* Advanced Squarewave AC provides a fast freezing weld puddle and deeper penetration
* Arc-start current crater current, current rising and down-sloping are all adjustable
* Built-in alarming and protective circuits are provided to prevent over current, over heat, over voltage,low voltage, etc and ensure safe operation
* Post-flow setting allows for proper shielding of both the weld end zone and electrode every time without waste of gas or need for adjustment
* Foot pedal controller connection availble, which facilitates welder’s operation
* Additonal 2T/4T function can make the welding operation more convenient, especially for long time welding
* DC products can weld steel, stainless and other alloys, but are not typically recommended for aluminum; while AC/DC products are capable of welding all metals, including aluminum

Square Wave™ Technology – Delivers a low peak current and fast positive / negative transition time. High frequency arc starting is used for both AC and DC TIG welding modes. You experience reduced tungsten spitting, tungsten electrode erosion and a smooth, stable AC welding arc.
Standard Auto Balance® control automatically delivers optimal mix of cleaning action vs. penetration.
Excellent low amperage starting performance – down to 10 amps.
It's Like Getting a Stick Welder for FREE!
With outstanding general purpose AC/DC stick welding capability, you can tackle steel, stainless, cast iron and hardfacing applications, including AWS E6010 electrodes like Fleetweld® 5P+.
Standard Foot Amptrol™
– Remotely controlling your current level is an added expense with other TIG welders in this class.
Enhanced TIG Torch Handling
– Includes a rugged Series 17 torch with Ultra-Flex™ cable. The torch is detachable for easy repair or to use optional torches for especially tight spaces or unusual applications.
Automatic Remote Sensing
– The unit automatically senses when a remote current control, such as the foot or hand Amptrol™, has been connected.
Shielding gas pre-flow and post-flow
– Built-in 0.50 second pre-flow and 15 second post-flow timers purge and protect the weld and tungsten.
