    Miller STH 160 DC Pulse TIG Welder, 230v
    Miller-STH160

    Select Option 
    Prices From £815.00 ex VAT

    Inverter-based, DC power source has a simple-to-use operator interface providing only the necessary controls in a compact machine. Portable in the shop or at the job site at 6Kg (13.2lb), the shoulder strap allows the end user to easily move from location to location. Built-in pulsing capabilities allow the operator to select from four fixed pulse frequencies to satisfy the application.

    Portable - in the shop or at the job site at 6Kg (13.2lb), the shoulder strap allows the end user to easily move from location to location.

    Digital meter - with presetting. Shows preset current before welding and actual value during welding.

    Lift-Arc™ - start provides TIG arc starting without the use of high frequency or the risk of tungsten contamination.

    HF start - for non-contact arc starting that eliminates tungsten or material contamination.

    Adjustable Hot Start™ - for Stick arc starts. Adjust the optimal start current for the application. The current automatically increases the output amperage at the start of a weld.

    Adjustable Arc force™- prevents sticking. Adjust the optimal arc force value. Adjustable arc force supports positional welding by increasing the output amperage.

    Built-in pulsing capabilities - allow the operator to select from four fixed pulse frequencies to satisfy the application.

    VRD function - a simple design that reduces the open-circuit voltage to 20 volts when the welding power source is not in use.

    230v TIG Welders FAQs

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

    Why choose a single phase 230v TIG welder?icon-minus-redicon-plus-red

    Single phase 230 volt is the supply found in homes, small workshops and many units, so a machine designed for it can be used almost anywhere without needing a three phase installation. Modern inverter designs draw relatively low current for the welding power they produce.

    That makes these machines popular for fabrication, repair, motorsport, restoration, pipework and light industrial work, as well as for home use.

    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.
