ENVY Multi 230 AC/DC Welder Unimig U11203

FEATURES:

• Single Pulse MIG: 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 performed using spray transfer, which eliminates spatter and reduces post-weld clean-up time.
• Double Pulse MIG: 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.
• Superior DC TIG Welding: Get unmatched welds on steel. With Direct Current (DC) TIG welding, you get smooth, stable arcs for flawless welds on mild and stainless steels, delivering clean results and maximum control on every joint.

MACHINE FEATURES:

• Power Factor Correction: 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
• Foot Control Ready: This machine supports the connection of both a wired and wireless foot control for extra versatility and convenience while welding. You can adjust your amperage hands-free to avoid disrupting your torch movement, and the wireless option reduces cables and adds greater manoeuvrability as well.
• 5” LCD Touchscreen: Navigation has never been easier. With the 5” LCD touchscreen, selecting your weld parameters or changing your settings mid-weld is effortless. Prefer physical buttons? Use the traditional control knobs to make all of your adjustments. 

MIG FEATURES:

• Digital 4 Geared Wire Drive: Experience unparalleled accuracy with our Digital 4 Geared Wire Drive system. Designed to sustain a consistent arc in varying conditions and with different wire types, it ensures an accurate wire feed speed. With this system, achieving precision in every welding task is effortless.
• MIG Smart-Set: Setting up for a weld has never been easier. Just set your wire material and size, gas, and joint type, and you’re ready to weld! 
• Push-Pull Gun 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.
• 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.
• 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.
• Spool Gun Ready: Make welding aluminium even easier. No need to change your existing setup. The spool gun lets you quickly switch over and get any job done with no downtime.
• 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.

TIG FEATURES:

• Higher Pulse Frequency in AC & DC: With a pulse frequency as high as 999 pulses per second in both AC and DC TIG, you can get as many pulses as you need for any scenario.
• Cap Shaping: Get the perfect tungsten shape for your aluminium welds every time with just the click of the trigger. Turn the cap shaping feature on, press the torch trigger, and the machine will prep the optimal tungsten shape for your aluminium welds. 
• Heat Control Trigger (HCT) Mode: Heat Control Trigger Mode lets you set a base current, which you can switch to at any time during a weld by pressing the trigger button. Heat Control Trigger Mode is great for manual heat input control as you go.
• TIG Smart-Set: The easiest way to set up for a TIG weld, simply set your filler material, joint type, tungsten diameter, and material thickness, and you’re good to go
• AC Waveforms: Customise your AC waveforms. Choose from your preferred welding waveform or use a combination of two to adjust the arc characteristics to suit your welding needs.
• Mixed AC/DC: Experience the best of both worlds. Mixed AC/DC combines the efficiency of AC and the penetration of DC-TIG in one weld. With it, you get faster welding speeds, better penetration, a faster weld puddle on cold workpieces, and you can weld on thicker materials.

MMA FEATURES:

• Power Limit: The adjustable power limit is designed to help maintain a constant power level while welding. Power limit automatically drops the current to a set limit and prevents it from rising to maintain a constant power when the electrode is lifted from the weld pool.
• Arc Force: The adjustable arc force adjusts the current (and, therefore, the heat) based on the length of the arc. When the arc becomes shorter, the current increases to keep it stable and stop the electrode from sticking. When the arc becomes longer, the current will decrease. It allows you to fine-tune your arc and improve your welds and consistency, especially in tight corners or when welding overhead or vertically
• Anti-Stick: The built-in anti-stick is designed to keep you from ever sticking an electrode again, whether you’re at the start of a weld, halfway through or about to end one. When the machine detects that the electrode is sticking, the current will shut off and unstick it.

ADDITIONAL FEATURES:

• Pulse MMA: Pulse MMA welding helps reduce spatter, improves heat control and allows for an easier removal of slag. It also improves the speed and efficiency of vertical up welds by eliminating the use of the “Christmas Tree” technique, while still maintaining root fusion. 
• Job Memory: The job memory function allows you to enter and store weld parameter settings. Weld parameters can be further adjusted and stored as required. A total of 100 Jobs can be memorised and stored for recall.
• 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.
• 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.
• Smart Fan: Smart Fan diminishes noise, saves power, helps reduce energy costs, and minimises the number of contaminants being pulled through the machine. 
• Tungsten Optimiser: Select the tungsten diameter and get an optimised welding arc ignition in AC and DC TIG based on the chosen diameter. 
• 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.
• Generator Compatible: Take it anywhere. Connect the machine to a generator and use it wherever, whenever you need it. We recommend 10kVA for this machine.
