Compact and multi-process, Master M delivers 350A MIG/MAG welding power with 40% duty cycle, including also stick and DC TIG welding.
Extend MIG welding experience
Designed and manufactured in Finland, Master M is a premium and compact MIG/MAG welding machine with synergic and pulse MIG welding model options. It elevates industrial welding performance, ensuring outstanding welding quality. Designed with professional welders, Master M makes everyday welding tasks effortless and fast.
Digital arc control, fast set-up techniques, and excellent power-to-weight set new standards for weld quality and work-based efficiency, boosting welding production. Choose from three class-leading models in the compact MIG welding machine category (353, 355, or 358), featuring alternative manual, synergic (Auto), and pulse (Auto Pulse) welding options. Weld with gas-cooled guns or select the optional Master M cooling system for an integrated liquid-cooled package that maximizes the 350A 40% ED welding power and enables more extended welding periods.
Experience new levels of welding productivity and control by switching on to MAX arc performance welding processes. They boost welding performance in challenging steel, stainless steel, and aluminum welding applications, making the seemingly impossible possible.
The integrated and self-charging LED work lights improve worksite safety, efficiency, and convenience. The LED light source operates with or without mains power, enhancing productivity in low-light conditions. The LED work light system is standard for all Master M compact MIG welder models.
Integrated digital connectivity opens a world of welding data through Master M, including three months free trial for WeldEye welding management software's ArcVision module, plus a digital WPS (dWPS) feature. Together, these welding quality management tools deliver the benefits of digital transformation to the very heart of the welding workplace.
Red Dot Product Design Award winner 2023.
Work safely in low light conditions
Improve working efficiency and safety with or without mains power connected. LED lightning is also included to the wire feed cabinet.
Worksite safety
Master M can be suspended above the ground with a safe-lift grab handle, which ensures safe lifting and movement at the site. Grab handle is also suitable for lifting the power source by crane. For longer distances, 2- and 4-wheel transport units are available.
Weld Assist guides towards optimal welding parameters
Weld Assist is a guidance tool for faster setup. Simply select the joint type, welding position, and material thickness and you’re ready to weld. An excellent instructive and educational tool. Weld Assist parameters can also be adjusted manually for individual preference.
Weld longer with maximum power
Master M series has two cooler options that keep the welding gun cool and the arc conditions smooth and stable. Cooler also features an easy-clean tank design and integrated LED lighting, which means you can keep an eye on the cooling liquid levels and make routine maintenance effortless. Optional cooler maximizes the use of the 350A power source with a 40% duty cycle.
Track arc on time and welding parameters
WeldEye ArcVision is an integrated Industry 4.0 solution that tracks and records arc-on time and welding parameters for better insight into welding production. Activate your free three-month trial license of WeldEye ArcVision with no obligation. The trial license also includes WeldEye’s Welding Procedures module, allowing the user to test the digital WPS (dWPS) feature. Integrated connectivity and WeldEye ArcVision are available in model 358.
Work pack of welding programs included
A pre-installed work pack of welding programs is included in all models, giving you a head start to welding. Work pack includes the most common welding curves for Fe, Ss, Al, CuSi, CuAl materials. In addition, Master M 355 and 358 models can be upgraded with optional welding software.
More control on weld pool in position welding
MAX Position helps manage gravitational effects on a molten weld pool. Improving control and confidence when working in the position, MAX Position is excellent when filling and capping in steel, stainless steel, and aluminum applications in the PF position.
Over 30% lower heat input
MAX Cool lowers heat input by up to 32%, improving control where excessive temperatures negatively impact weld pool stability and increase joint distortion. MAX Cool is ideal for a variety of applications, including thin sheet fabrication, root welding, gap bridging, and joining thin extruded sections in solid Fe, Ss, CuAl8, and CuSi3 filler materials.
Up to 70% faster welding travel speed
MAX Speed increases welding travel speed by up to 70%* compared to traditional pulse or spray arc processes. MAX Speed produces clean top-quality weld seams, effectively reducing labor time and welding cost. MAX Speed is designed for steel and stainless steel welding applications in the PA and PB positions. Note:(*) Maximum travel speeds measured in automated and semi-automated Ss applications. Speed reductions apply in manual welding applications and Fe material.
25% faster welding
WiseFusion produces a very narrow and energy-dense arc that allows welding at a significantly higher speed without the risk of undercut. WiseFusion is up to 25% faster than conventional synergic 1-MIG and pulsed MIG, and it also facilitates weld pool control in position welding. Adaptive arc length regulation eliminates the need for constant parameter adjustment.
Customize your screen
You can add a personalized screen-saver image to Master M 358. The image must be prepared at https://kemp.cc/screensaver (see the Read more link) and then copied onto a USB memory stick. The supported image files are JPG, PNG, and GIF. Connect the USB memory stick to your welder's USB port and you are ready to go!
Gas guard
Connect your welding machine to a centralized shielding gas supply. The Gas Guard function prevents welding if the shielding gas supply is interrupted or is not connected. The Gas Guard feature is standard on 355 and 358 models.
Automatic calibration
Auto cable calibration ensures quality assurance even before welding starts. It measures the welding circuit resistance and calibrates the digital meters, ensuring the arc voltage displayed accurately matches the arc voltage at the welding gun. It is critical for accurate WPS compliance. The calibration must be repeated whenever you change the length of the interconnection cable, earth return cable, sub feeder cable, or welding gun cable.
Easy access to information with QR code
Each Master M model is equipped with a unique and scannable QR code. It enables easy access to all the relevant information such as product number, serial number, technical specifications, ordering codes, consumables, user manuals, websites, and local dealers' or workshops’ contact information. All the information can be found with a single mobile scan.
