    415v TIG Welders FAQs

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

    What is the supply requirement?icon-minus-redicon-plus-red

    A three phase machine needs a suitable three phase supply with the correct voltage and protection. The data plate and manual specify the voltage range, input current and fuse or breaker size. Many machines accept a range of three phase voltages.

    Have the installation, cable and isolator fitted and checked by a competent electrician. Do not use adaptors or improvised connections, and make sure the supply capacity suits the full welding output.

    Can I run a three phase TIG welder from a generator?icon-minus-redicon-plus-red

    Sometimes, but only if the generator is a three phase unit suited to the welder. Check the data plate and manual for your machine for its input current and any minimum generator size or type the maker states.

    Generators are rated for balanced three phase loads, and power factor affects the size you need, so allow a generous margin above the welder's input requirement. The output must be stable and well regulated. An undersized or poor quality generator can cause cutting out, an unstable arc or damage to the electronics. If in doubt, ask the maker or a competent electrician before connecting.

    How do I choose the output rating?icon-minus-redicon-plus-red

    Consider the thickest material and the metal. Aluminium needs more current than steel for the same thickness. Choose a machine with a maximum current comfortably above what you will need regularly, since this gives a better duty cycle, a cooler running machine and headroom for heavier jobs.

    Also consider the lowest current. A machine with a low, stable minimum current suits thin material and precise work. A wide range between minimum and maximum makes the machine more versatile.

    AC/DC or DC only: which do I need?icon-minus-redicon-plus-red

    A DC machine welds steel, stainless steel, copper and many other metals, but not aluminium or magnesium. An AC/DC machine adds AC output, which cleans the oxide layer on aluminium and magnesium so they can be welded properly.

    If you will ever weld aluminium, choose AC/DC. Look for adjustable AC balance and frequency, which let you tune the cleaning action and the arc focus.
