ESAB Welding & Cutting Products is offering the new family of Heliarc machines for high-quality AC/DC GTAW (TIG) and SMAW (Stick) welding.
Three new Heliarc TIG welding machine models are being offered: the Heliarc 281i, a 280-amp unit for single-phase 230 connections; the Heliarc 283i, a 280-amp unit for three-phase 460 connections; and the Heliarc 353i, a 350-amp three-phase 460 unit for more power when welding thicker materials.
All three machines use inverter technology, which delivers increased energy efficiency and superior functionality—all in a package that is lighter, smaller, and less expensive.
Heliarc offers easy-to-control arc heat input, which results in quality welds. The pulse current allows for lower heat dissipation, better control of the weld pool, and less plate deformation.
DC pulsing, with square wave, cuts current peaks and provides symmetric power, a stable arc, and perfect interfusion between base and filler material. AC pulsing up to 2 hertz makes Heliarc ideal for welding thin aluminum material.
In AC mode, the arc is designed to only use high frequency at the start, reducing electrical noise and the risk of interference with surrounding electronics. High frequency can be switched completely off in favor of an electronic live TIG start when welding in areas where high frequency is not permitted due to electronic disturbance issues.
Heliarc’s control panel is easy to set up and operate. Five clear sections on the control panel allow the operator to choose options and settings needed.
All controls are centrally located. Easy-to-use buttons provide slope down, pulse current, background current, pre-gas, post-gas, pulse, and duty options. The machine’s memory can store and recall up to 60 user-defined welding programs.
Choose between Stick, TIG 2-, and four-stroke mode (trigger latch), TIG spot, and trigger-enabled peak to background current, which can be used as a manual pulse to decrease heat and better control puddle fluidity while welding. In stick mode, the submenu allows for access to Hot Start and Arc Force settings. The Heliarc 281i AC/DC is a single-phase 50/60-Hz unit with 208-230-volt input and a maximum TIG AC/DC output of 250 amps at 100% duty cycle. The Heliarc 283i AC/DC is three-phase 50/60-Hz unit with 460-volt input and a maximum TIG AC/DC output of 280 amps at a 100% duty cycle. The Heliarc 353i AC/DC is three-phase 50/60-Hz unit with 460-volt input and a maximum TIG AC/DC output of 280 amps at a 100% duty cycle.
The Heliarc 281i and 283i are available as ready-to-weld air- and water-cooled packages and include the power source, 25-foot torch, foot control, work cable, regulator flowmeter (ArCo2), and cart.
The Heliarc 353i is provided in a water-cooled ready-to-weld package and includes the power source, cooler, 25-ft torch, foot control, work cable, regulator flowmeter (ArCo2), and cart. For more information, visit www.esabna.com.
