The new Weldarc 200i DC welding machine is easily portable and suitable for a variety of environments
Welding Industries of Australia (WIA) has launched a new welding machine it says will meet the needs of all professional TIG welders.
WIA says the Weldarc 200i DC is “a much more sophisticated machine” than the compact DC IV/Stock models offered by WIA, including its Weldarc 185i and 145i.
In an announcement, the company says that while the other models target stick welding applications, with the option for Lift TIG welding, the new Weldarc 200i DC is primarily designed for TIG welding, featuring a 200 Amp DC TIG capability, while still retaining a 170 Amp stick welder capability.
This means the machine is also perfectly suited for professional stick welding applications, it adds.
WIA equipment development engineer Willem Corbett says the Arc Start on the 200i can be through either the High Frequency (HF) Pulse non-contact starting method, or the Lift Arc method.
“Both options ensure minimum electrical interference during Arc Start, while HF also eliminates the risk of tungsten electrode contamination,” he says.
That said, Corbett says the HF Pulse non-contact method is one of the 200i’s key features.
“During the arc start process, pre gas flow is provided through an integrated gas valve, the HF Pulse start then ignites the arc without any risk of tungsten contamination,” he says.
“The Lift Arc method also eliminates scratch starting and tungsten electrode damage.”
In the stick welding mode, the Weldarc 200i DC has a built-in “Hot Start” feature, allowing the machine to deliver a peak of current when striking the arc.
Alongside this, the 21kg 200i welder is easily portable, and can be readily transition from indoor to outdoor work.
“Being a single phase machine, the Weldarc 200i DC can easily be taken to the site and plugged in to continue welding on site,” Corbett says.
“The built-in Power Factor Correction (PFC) feature also makes the machine tolerant to unconditioned power when generators are used, and tolerant to being operated on long extension leads.”
Corbett adds that the Weldarc 200i DC has an IP23S rating, meaning it is designed to be tolerant to outdoor environment.
“The IP23S rating means the machine is protected against water sprays and some level of atmospheric humidity,” he says.
“But we do not recommend using the machine for welding in the rain or in very wet environments.”
It also comes with a built-in voltage reduction device, operating in accordance with AS1674.2 CAT C requirements, and a thermal overload shut down function to prevent overheating.
“The on-demand fan option further reduces ambient noise and prevents dirt and dust from entering the welding machine,” Corbett adds.
The new professional Weldarc 200i DC machine by WIA comes with a three-year unlimited Australia-wide warranty, which covers both parts and labour.
