Automated Plasma Power Sources for High Precision Plasma Cutting

ESAB I-Series automated plasma cutting systems, available in 100- to 400-amp configurations

ESAB has launched its I-Series of high-precision automated plasma cutting power sources that are designed to deliver higher productivity. The I-Series is available in 100-, 200-, 300- and 400-amp configurations for cutting plate up to 50 mm thick. All models feature a common cabinet and components as well as StepUp modular technology, allowing users to increase the output from 100 amps all the way up to 400 amps by adding inverter blocks.

"The ability to add inverter blocks means fabricators never have to worry about purchasing a system that does not have enough capacity to meet future needs," said Steve Zlotnicki, Product Line Manager, Cutting.

The I-Series power sources can be implemented in the Combirex DX gantry cutting machine. "The heavy-duty precision gantry offers smoother motion and contains an easily installed h-beam mounted rail that provides a sturdy foundation and excellent rail protection," said a company spokesperson. ESAB's Vision T5 touchscreen controller has a built-in process database and optional automatic nesting.

"Providing ISO Class 3 or better cuts on any material from gauge to 50 mm thick, the I-Series reduces bevel and improves edge quality, reducing the need for post-cut finishing," said the spokesperson. Choices for plasma gas include air, nitrogen, oxygen and argon-helium, with argon for marking. Shield gas choices include air, nitrogen, oxygen and water as part of the Water Mist Secondary (WMS) process, which incorporates nitrogen as the plasma gas and ordinary tap water for shielding.

"The I-Series torch dual gas technology provides one of the highest arc density plasma streams in the industry for precision cuts, as well as the highest kW output for maximized duty cycle and cut speed," said Zlotnicki. "On mild steel, the I-Series provides a combination of cut quality and performance."

The I-Series torch features the SpeedLok cartridge, which removes in seconds with a simple twist and no tools required. Users can minimize downtime by keeping extra cartridges on hand to change consumables for cutting at different amperages, replacing worn consumables or switching to the WMS or marking process.

The I-Series uses XTremeLife Wear Parts for cutting at 200, 300 and 400 amps. These consumables use a multiple hafnium insert as opposed to a single insert and feature a two-piece tip that runs cooler. Better cooling extends parts life and cut accuracy across the life of the tip, especially when piercing at higher amperages.

To further extend consumables life in higher amperage applications, ESAB developed HeavyCut Technology, an enhanced arc start/stop routine. "Tests show that HeavyCut can increase arc starts from an average of 900 to 1,300 starts per set of consumables," said the spokesperson.
