Precision TIG Part 4: Rated Output


In recent issues of Lincoln's i-Weld newsletter, we have focused on the attributes of the Precision TIG® 275 and 375 welding units. We have illustrated the machine's superior arc performance, innovative value features and ease in set-up. This time, we turn our attention to the Precision TIG's low input current draw, its ability to provide the highest rated output, and its broader amperage range compared to its nearest competitor. For customers, this means more output versatility with the lowest input current draw.

 GTAW: Precision TIG Series Part 4 - Rated Output, Current Range and Input Current

 

 

 

 

 

 



In designing the new Precision TIG®, Lincoln wanted to find out what customers really wanted in a TIG machine. To do this, a team of engineers held extensive interviews with customers, distributors and sales personnel to put together a 'wish list' of items that welding operators and company management would like to see.

During these interviews, it was noted that customers wanted a versatile machine that could deliver a wide amperage range to tackle the thinnest material up to heavier weldments. High input current draw was also a concern, especially in fabrication shops that utilized 208v input power. Some customers stated that, with the competitive TIG welders they were currently using, they needed to shut off other equipment in order to weld without tripping circuit breakers.

Taking these concerns under consideration, the Precision TIG® was designed to provide a higher rated output compared to competitive models. The Precision TIG®, featuring Micro-Start Technology™, also has the ability to weld down to lower currents than its competition. Finally, the Precision TIG® draws less current at comparable output levels. This means the Precision TIG® is the unit of choice when it comes to output capability with low current draw.


Review the Numbers for Yourself

As an example of the benefits provided by the Precision TIG®, compare the output ratings of the two Precision TIG® models with those of their nearest competitors, the Syncrowave models from Miller Electric Manufacturing, Inc®.
