    Experience unfailing precision arc performance paired with a state-of-the-art, user-friendly interface that puts advanced capabilities at your fingertips. Dynasty TIG power sources help minimise error and achieve high-precision welds every time, making the best welders even better.

    Features

    • Easy-to-understand interface with a 4.5" LCD ensures proper machine setup and parameter selection. Informative on-screen explanations and dynamic images enhance the parameter selection process.
    • Program memory allows easy naming, saving, and recalling of favourite weld settings. Deliver more productivity by eliminating the need to manually set the parameters. Deliver consistent quality by welders of all skills.
    • Pro-Set eliminates the guesswork when setting weld parameters.
    • Locks and limits provide control of the weld parameter range minimising deviation from the welding procedure specification (WPS).
    • MIG/MAG (GMAW) Mode allows the operator to attach and run a suitcase feeder off the power source for high-productivity welding.
    • Blue Lightning provides more consistent high-frequency (HF) arc starts and greater reliability compared to traditional arc starters.
    • USB front panel port provides the ability to easily update software, back-up settings and transfer saved weld programs from one unit to the next.
    • Cooler Power Supply (CPS), an integrated 120-volt dedicated-use receptacle for the Coolmate 1.3.
    • The Cooler-On-Demand feature operates the auxiliary cooling system only when needed, reducing noise, energy use, and airborne contaminants pulled through the cooler.
    • AC TIG Features. Balance control provides adjustable oxide removal which is essential for creating the highest-quality aluminium welds. Frequency controls the width of the arc cone and can improve directional control of the arc.
    • AC Waveforms. Advanced square provides a fast-freezing puddle, deep penetration, and fast travel speeds. Soft square for a soft buttery arc with maximum puddle control and good wetting action. Sine for customers that like a traditional arc. Quiet with good wetting. Triangular reduces the heat input and is good on thin aluminium. Fast travel speeds.
    • Independent amplitude/amperage control allows EP and EN amperages to be set independently to precisely control heat input to the work and electrode.
    • AC/DC Stick Features. DIG control allows the arc characteristics to be changed for specific applications and electrodes. Lower the DIG setting for smooth-running electrodes like E7018 and increase the DIG setting for stiffer, more penetrating electrodes like E6010. Hot Start adaptive control provides positive arc starts without sticking. AC frequency control adds additional stability when stick welding in AC for smoother welds. Stick-Stuck detects if the electrode is stuck to the part and turns the welding output off to safely and easily remove the electrode. Menu selectable.
    • DC TIG features an exceptionally smooth and precise arc for welding exotic materials.
    • Pulse Waveforms. Square provides a fast-freezing puddle for ultimate arc control. Sine produces a reduced audible sound and provides a more fluid puddle that is good for overlaying applications. Triangular provides a quick-forming puddle while further reducing heat for thin materials.

    230v TIG Welders FAQs

    Straight answers to the questions people ask most when choosing and using single phase TIG welders.

    How much power can I get from a 230v supply?icon-minus-redicon-plus-red

    The supply limits the maximum welding current. A standard 13 amp socket gives less power than a dedicated higher-rated supply, so the output you can use continuously may be lower than the machine's maximum. Check the data plate for the input current at full output, and what protection it needs.

    For higher currents or heavier duty, a dedicated circuit installed by a competent electrician may be needed. Do not assume a plug-in connection will suit full output.

    Should I choose DC or AC/DC?icon-minus-redicon-plus-red

    DC machines weld steel, stainless steel, copper and other metals except aluminium. AC/DC machines add alternating current, which breaks up the oxide layer on aluminium and magnesium, so they are needed for those metals.

    If you will weld aluminium at all, choose AC/DC. If you only weld steel, stainless and similar metals, DC is simpler and more economical. AC/DC machines normally also offer controls for balance and frequency, to fine-tune the arc.

    What size of machine do I need?icon-minus-redicon-plus-red

    Think about the thickest material you will weld and the process, and choose a rating with some margin. Aluminium needs considerably more current than steel for the same thickness, and heavier sections need more again.

    Also consider duty cycle, which describes how much of each ten minute period the machine can weld at a given current. A machine rated well above your usual working current runs cooler, lasts longer and is more pleasant to use.

    What is a multi-voltage TIG welder?icon-minus-redicon-plus-red

    A multi-voltage machine adapts to different supplies, for example running on both 110 and 230 volts, and sometimes wider ranges. This suits people who move between site and workshop or use different supplies.

    The output you get depends on the supply connected, with less at lower voltages. Check the specification at each voltage, and make sure the plug, cable and protection match the supply you connect to.
