TIG Welding Series: The Power to Perform
Part 4: Rated Output, Current Range & 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.
The Precision TIG delivers 25 more amps of output at the same duty cycle! In addition, the Precision TIG delivers an overall wider amperage range. Now compare the Precision TIG 275's input current draw at the same output amperage level to the Syncrowave 250DX: Precision TIG 275 Current Draw Competitive Comparison
The Syncrowave 250DX draws up to 10% higher input current and delivers 40% less duty cycle (based on available literature at the time of this printing)! Precision TIG 375 Current Draw Competitive Comparison
The Syncrowave 350LX draws almost 20% higher input current draw and delivers 40% less duty cycle (based on available literature at the time of this printing)! Conclusion To view previous Precision TIG articles in this series click on the following links:

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.
