Inverter welding machines, engineered since 1973
Robust inverter-based welding machines for MMA, MIG and TIG, engineered for high duty cycles in the most demanding industries.
01 — About Newarc
Manufacture
Established in 1973, Newarc specialises in designing and manufacturing robust inverter-based welding equipment for MMA, MIG and TIG applications.
Build
Machines are engineered for reliability and ease of use, meet international standards and are rigorously tested to ensure high duty cycles. They're built for work, not for the showroom.
Industries
Newarc serves the industries that punish equipment hardest: oil and gas, petrochemical, shipbuilding, construction and aerospace.

02 — The Newarc range
Six machines and packages across MMA, MIG and TIG. Every one is quoted per order rather than sold from a list price. Tell us the duty cycle, the process and the torch length you need and the team will price it.
MIG 400A industrial Newarc MIG 400 Industrial MIG/MAG Welder Package The one that runs all shift without backing off. MIG400 heavy-duty MIG/MAG package at a 100% duty cycle, with a 3m, 4m or 5m torch. Enquire / quote 
TIG 250A HF Newarc Viper 2500S TIG Control Unit High-frequency start, without the scratch. The Viper 2500S control unit: 250A high-frequency TIG control for clean, repeatable arc starts. Enquire / quote 
TIG 200A HF Newarc Viper 2000 HF TIG Control Unit The same control, sized for lighter work. The Viper 2000 HF control unit: 200A high-frequency TIG for thinner material and finer work. Enquire / quote 
TIG / MMA 250A Newarc RT2500 MMA/TIG Inverter Welder Two processes, one three-phase power source. The RT2500 inverter delivers 250A MMA and TIG from a single three-phase machine. Enquire / quote 03 — Common questions
Newarc equipment is quoted per order rather than sold from a list price, because the specification changes with duty cycle, torch length, cooling and whether you need a complete package or a power source on its own. Use the enquiry button on any machine and the team will price the build you actually need.
A control unit is the TIG high-frequency control on its own, to run alongside a power source you already have. A complete package is everything matched and supplied together (power source, feeder, torch and interconnection), so nothing is missing when it arrives.
Yes. They are designed and manufactured to meet international standards and rigorously tested for high duty cycles, which is why they are specified in oil and gas, petrochemical, shipbuilding, construction and aerospace.
Often, yes. Talk to Robson and the field sales team about a demonstration. It is the quickest way to settle a choice between two machines, and it costs nothing.
