Features:

• Not All Pulse Machines Are Equal. With the single and double pulse functions, you can streamline your welds with no spatter, less heat, and the same penetration.
• Single Pulse: A single pulse weld alternates between a peak and base current, which works to minimise the amount of heat input without compromising on any of the penetration. The addition of a base current and reduction in heat means it’s perfect for softer materials like aluminium. Pulse welding is also done by spray transfer, eliminating spatter and cutting your post-weld clean-up time.
• Double Pulse: A double pulse weld alternates between a peak current and two base currents, reducing the heat input of the weld even further than single pulse, while still maintaining all of the benefits. Because of the faster freezing puddle, your double pulse welds come out looking just like a stack of dimes. You get the aesthetics of a TIG weld with all the speed of spray MIG.
• 100+ Smart-Set MIG Programs: Getting set up for a weld has never been faster with over 100 synergic programs. Simply select your metal type, wire size, gas type, and material thickness, and the machine does the rest. It’ll pick the optimal settings for your weld.
• Modular Add-ons: Futureproof your purchase with the EVOLVE MULTI 400 PULSE, with the option to add additional modules as you need them. These optional modules include a Separate Wire Feeder (SWF) module and an AC/DC TIG module for all your future needs.
• Power Sense Technology: Experience unmatched flexibility with dual voltage power sense. Connect the three-phase to single-phase plug adapter and switch between 32A three-phase and 15A single-phase plugs as you need. When in single-phase, the machine’s output is limited to a maximum of 250A.
• Hot Start: Get the smoothest arc start possible. The Hot Start function gives a boost of current at the beginning of your weld, eliminating any issues with starting on cold metal, letting you weld on thicker materials, and making welding aluminium even easier.
• Crater Fill: End your welds as strong as they started. Crater Fill ramps your welding current and voltage down at the end of a weld, filling it in at a lower amperage, eliminating craters and pinholes.
• Longer Torch Consumable Life: Get superior life out of every torch consumable. Designed for maximum performance, you’ll get 6x longer life with Arc Torchology consumables.
• Contact Tip Performance: The Arc Torchology contact tips lasted up to 6x longer, withstanding the maximum amperage for 30 hours vs the Binzel 501D’s 5 hours.
• Gas Nozzle Performance: The Arc Torchology gas nozzles lasted up to 3x longer, withstanding the maximum amperage for 75 hours vs the Binzel 501D’s 25 hours.
• Tip Adapter Performance: The Arc Torchology tip adapters lasted up to 5x longer, withstanding the maximum amperage for 250 hours vs the Binzel 501D’s 50 hours.
• Cooler Running Torches: The Arc Torchology tip adapters lasted up to 5x longer, withstanding the maximum amperage for 250 hours vs the Binzel 501D’s 50 hours.
• Less Maintenance & Downtime: Spend less time cleaning your consumables and have them last longer with 90% longer with less spatter adhesion.
• Contact Tip Performance: The Arc Torchology contact tips had 90% less spatter adhesion on the tip’s face, with only 9% spatter vs the Binzel 501D 100%.
• Gas Nozzle Performance: The Arc Torchology gas nozzle had 33% less spatter adhesion on the nozzle’s face, with only 67% spatter vs the Binzel 501D’s 100%.
• Push-Pull Ready: Achieve smooth and steady wire feeding, especially when using softer wires such as aluminium. With a ‘Pull’ motor built into the torch, the wire can be fed over a greater distance, granting you the freedom to move and manoeuvre with ease while MIG welding.
• Power Factor Correction (PFC): Get the most out of your machine. The PFC maximises the electrical efficiency of the machine and automatically compensates for any voltage fluctuations, so you get more output power and the internal components last longer.
• Inverter Technology: Not every inverter is made equal. With UNIMIG’s ever-evolving, state-of-the-art IGBT Inverter technology, you get better performance, better efficiency, and better reliability.
• 4 Geared Wire Drive: The most consistent and smoothest wire-feeding experience there is. With a four-gear wire drive unit, there’s more power pushing the wire, improving the wire-feeding, especially with longer torches.
• IP23S: Rated IP23S, so it’s protected from touch by fingers and objects greater than 12mm, and water spray less than 60° from vertical while still.
• Advanced MMA Features: Advanced MMA features are designed for improving weld quality and ease of use.
• Arc Force: The Arc Force feature helps to keep the arc stabilised throughout the weld, by increasing or decreasing the peak current to compensate for your arc length, preventing the arc from cutting out or the electrode from sticking.
• Anti-Stick: The Anti-Stick feature, which is always on, prevents your electrode from sticking to your workpiece. When the machine detects sticking, the current will drop significantly, so the electrode can be removed.
• Hot Start: The adjustable hot start is designed to help with striking an arc. The hot start temporarily boosts the output current at the start, making striking an arc, even with difficult electrodes, much easier. You get smoother arc starts, improving the quality of your weld.
• Job Memory: Save all of your favourite settings with the Job Memory feature. With up to 100 saves available, you’ll never need to memorise your parameters again. Plus, seamlessly switch between different jobs with the touch of a button.
• Digital Control Torch: Our digital MIG torch allows you to adjust your settings on the fly. Change the amps, current, and voltage at the touch of a torch button.
• Large Wire Spool Capacity: Fits both D200 and D300 wire spools, so you can put 15kg of mild steel or 7kg of aluminium spools in the machine.
• Robotics Connection: The robot connection lets you integrate a robotic arm into your workflow, which can improve the precision, consistency, and efficiency across welding tasks. It allows for automated, repeatable welds, reducing human error and improving productivity.
• CO2 Preheater: Plug Connect a preheater for your CO2 regulator with the preheater plug to prevent it from freezing during prolonged use. Keeping the gas heated allows a consistent gas flow and stops fluctuations or reductions in the gas flow.
• Adjustable Arc Length: Get absolute precision on your settings. The adjustable arc length allows you to increase or decrease the preselected voltage while in synergic and pulse MIG modes.
• Inductance Control: Take complete control of your arc with the inductance settings. By changing the frequency of your short-circuit MIG welds with the Inductance controls, you can choose your preferred arc characteristics on every weld.
• Burnback Adjustment: Stop your wire from ever fusing with your weld or your contact tips again. Tune your burnback control to suit how much wire you want to remain sticking out from your torch when you finish a weld.
