Superior welding solutions

Our welding solutions set industry benchmarks in terms of efficiency, performance and safety. Key benefits include relatively high duty cycles, low power consumption and in-built safety features. Some of our products have become standard reference for welding equipment within certain industry sectors and/or applications.


MIG/MAG, TIG and MMA Welding

In the oil and gas industries, base materials vary from normal steel to highly chemically resistant super-alloys. Oil production welding often involves repairs and maintenance in difficult conditions and with special materials, like high-alloy steels, titanium, and hard-facing. Oil refineries use special heat- and creep-resistant steels. Pipeline construction is moving to high-strength steels, and contractors are in search of more productive welding methods.


MMA and TIG processes are widely used for pipe welding, and the MIG process is used when components are manufactured in workshops.


Ideal for applications requiring a powerful, quality weld, the Kemppi Fastmig family of Mig welding solutions is the professional choice for those in heavy industry. The range includes both gas and water-cooled options in Basic, Synergic and Pulse formats. Basic and Synergic are available in 300amp, 400amp and 500amp power sources while the Fastmig Pulse range includes 350amp and 450amp versions.



TIG Welding
MasterTig AC/DC 3500W - A powerful TIG welding machine suitable for all types of materials, with many functions and several control panel options.

MasterTig MLS ACDC - A versatile line of products for the TIG welding of aluminium and stainless steel and for MMA welding. Suitable for both manual and mechanised welding.



MMA Welding
Kemppi MMA welding products include the Master and Minarc series. The Minarc Evo range is portable, easy to use and delivers outstanding welding quality. View the Kemppi Minarc Evo product family video to find out more.


Comprehensive welding solutions

Kemppi Arc System 2.0, module ArcQuality (ArcQ), provide accurate and formal qualitative proof that welding has been completed using approved parameters, filler materials and qualified personnel.



ArcQuality identifies WPS deviations and validates welding quality. Measuring and recording welding parameters and consumables used, comparing the information collected against the qualified welding procedure specification, providing a formal solution that defines and verifies welding quality, avoiding deviations that can result in serious quality issues if left unchecked.



System highlights:

  • Monitors compliance to the WPS
  • Ensures welders hold valid qualification
  • Creates non-conformance reports
  • Automates data collection
  • Reduces rework costs
  • Supports the welder, quality and management personnel
  • Reports arc and non-arc time Includes a welding fleet management tool
  • Anticipates service needs and records service history
  • Designed for monitoring MIG/MAG welding
  • Web based reporting WLAN technology
