110v TIG Welders

Site regulations often require portable equipment to connect to 110volts AC supply. Our 110v TIG Welding machines give portablity and good welding power when connected to 110v mains or generated power.

110v TIG Welders FAQs

Straight answers to the questions people ask most when choosing and using TIG welders for 110 volt site supplies.

Why would I choose a 110v TIG welder?icon-minus-redicon-plus-red

On many UK building sites, shipyards and industrial locations, 110 volt supplies from a centre-tapped transformer or generator are the preferred or specified way to power portable equipment, because they reduce the risk of electric shock in damp or rough conditions. A TIG welder made to run on 110 volts lets you work to those site rules without extra equipment.

Many of these machines are portable inverters, light enough to carry. Some are multi-voltage machines that also run from 230 volts, which gives flexibility between site and workshop. Always check your site rules and the machine's data plate.

How much can I weld on a 110v supply?icon-minus-redicon-plus-red

A 110 volt supply can supply less power than 230 volts for the same plug and fuse size, so the maximum welding current is lower than on the same machine at 230 volts. That still suits thin and medium material, pipework and many repair jobs.

Check the rated output at 110 volts on the data plate or specification, not the headline figure for 230 volts. Thicker material, or long runs at high current, may need a higher supply or a bigger machine.

What does a multi-voltage machine do?icon-minus-redicon-plus-red

A multi-voltage machine senses the supply and adjusts to suit, so the same welder can run from 110 volts and 230 volts, and sometimes other ranges. This gives flexibility if you move between site and workshop.

Remember that the output you get depends on the supply it is connected to, and that the plug and fuse or breaker must match. Always check the manual for the maximum current at each voltage.

Can I run a 110v TIG welder from a generator?icon-minus-redicon-plus-red

Often yes, if the generator is large enough and produces a clean, stable output. Inverter welders can be sensitive to poor quality power, so check the generator's output rating, waveform and regulation against the welder's requirements.

A generator that is too small will cause cutting out or damage. The welder manufacturer's guidance on generator size and type is the best guide, and a 110 volt transformer or centre-tapped output is often used on site. If unsure, ask before connecting.

Why is my machine cutting out or tripping?icon-minus-redicon-plus-red

On a 110 volt supply, the current drawn is high, so supply and cable problems show up quickly. Common causes are an undersized or very long extension cable, an overloaded supply or transformer, a tripping breaker rated too low, or too many tools on the same circuit.

Use the shortest, heaviest extension lead that is suitable, make sure the supply can provide the needed current, and run the welder at a current the supply can sustain. If the machine has a thermal protection light, allow it to cool.

Do I need a special extension cable?icon-minus-redicon-plus-red

Yes, use a cable properly rated for the current the welder draws, and keep it as short as practical. A thin or very long cable drops voltage, which reduces welding power and can make the machine cut out. Extension reels should be fully unwound, since coiled cable can overheat.

Use site-approved 110 volt cable and connectors in good condition. Check the manual for the recommended cable size, and have any doubtful equipment inspected before use.
