HELIARC®. THE FIRST NAME IN TIG.

YOU AND HELIARC.

NOT EVERYONE APPRECIATES THE BEAUTY OF A TRULY

GREAT WELD. BUT YOU DO. YOU’VE PUT IN THE YEARS

AND MASTERED THE ART AND CRAFT OF GTAW (TIG).

AND EVER SINCE THE PROCESS WAS INVENTED, HELIARC

HAS BEEN SYNONYMOUS WITH TIG WELDING. WITH

BEST-IN-CLASS PERFORMANCE ACROSS AC AND DC

TIG, THE LOWEST COST OF ACQUISITION, AND ESAB’S

LEADING-EDGE TECHNOLOGY AND ENGINEERING, THESE

MACHINES ARE WORTHY OF YOUR SKILL.

Easy-to-Use Interface

The control panel of this advanced TIG unit is

divided into 5 clear sections, making it easy to

choose the options and settings you need for fast

set up and excellent arc control. The machine’s

internal communication is entirely digital to give

you high accuracy and repeatability.

Two Versions AvailableHeliarc 283i – 280 A unit for 3-phase 400 connections

Heliarc 353i – 350 A unit for 3-phase 400 connections (For more power when welding thicker materials.)

Choose between MMA, TIG 2- and

4-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 MMA

mode, the submenu allows for access

to Hot Start and Arc Force settings.

Displays power status, output, over

temperature indicator, and features two

digital displays that provide a variety

of user-selected information.

All control settings are centrally located.

Easy-to-use buttons provide slope down,

pulse current, background current,

pre-gas, post-gas, pulse, and duty

options. Heliarc also allows you to

store and recall up to 60 programs.

Specific AC settings include wave form

control for pulsing, frequency, and balance.

Easily choose your preferred start, with

or without high-frequency and remote

control on/off. Additionally, remote

minimum and maximum can be pre-set

in a submenu.

AC Balance

Controlling arc cleaning and penetration is easy

with the AC Balance setting, as is regulating the

heat on the electrode.

Pulsing

Pulsing allows for lower heat dissipation, better

control of the weld pool, less plate deformation,

and more even welds. Both AC and DC pulsing is

used to regulate heat input and control the pool,

making it perfect for welding thin materials. DC

pulsing, with square wave, cuts current peaks and

provides symmetric power, a stable arc, and perfect

interfusion between base and filler material.

The duty setting allows for an easy adjustment

between pulse and background time.

Immediate Control of Heat Input

Controlling the heat in your arc is easy with

either the optional FC-5C foot control or TIG torch

mounted remote current control. Additionally, these

machines feature a manual pulsing heat control

function to optimise operator control during welding.

Simply pressing the torch switch quickly reduces

the current to a pre-set base and pressing it again

returns it to the set current.

High-Frequency Start

Count on high-quality, accurate, and exact starts. In

AC, the arc is designed so that the high frequency is

only needed upon start, reducing electrical noise and

risk of interference with surrounding electronics. When

welding in areas where electronic disturbance is an

issue, the high frequency can be switched off entirely

and an electronic Live TIG start can be used.

ADDITIONAL FEATURES.

Inverter Technology

State-of-the-art inverter technology means

you benefit from energy savings and superior

functionality right from the start, all in a package

that is lighter, smaller, and less expensive than

old technology SCR machines.

AC Frequency

Allows control of arc width and penetration,

making both wider arcs with less penetration

or narrow arcs with deep penetration and

faster speeds achievable. Wider arc with lower frequency

Narrow arc with higher frequency

60 Program Storage

Increase your productivity by easily storing

up to 60 parameter sets for quick changes

while working.

Compliance with the Highest Standards

Heliarc 283i, and 353i have been designed

to meet the highest international standards.

Energy Efficiency

Lower power requirements mean you save money

and get a faster return on your investment. Enjoy

the convenience of lower current draw, a smaller

and more manageable power cord, and the ability

to use a more compact generator when working

in the field.
