Expert Advice

Paul Jones says

This type of liquid-cooled induction heater is used for controlled, flameless heating in vehicle repair and general workshop work. I use it mainly for seized bolts, nuts, bearings, hubs and bonded components where applying heat locally is safer than using a torch around paint, wiring or other vulnerable parts.

The 3.5 kW output runs from a 230 V supply and uses interchangeable coils, so the coil must suit the shape and material being heated. Steel and other ferrous materials respond well, while aluminium and non-ferrous parts require the correct application and may not heat in the same way. Keep the coil close to the work without touching it, and allow clearance around adjacent components.

A common issue is poor coil positioning, which gives slow or uneven heating and encourages excessive dwell time. The liquid cooling system also needs the correct coolant level and unobstructed hose routing.

Used with the right coil and sensible heat control, this is a reliable workshop tool that reduces damage and makes difficult component removal more predictable.

FAQs

What is the AES HI 3.5 suitable for in a professional workshop?

It provides controlled, flameless heat for removing rusted nuts, bolts, bearings, hubs and other seized metal parts. It is also useful for pre-heating before welding or soldering, shrinking, bending and general repair work on cars, commercial vehicles and industrial equipment.

What power supply does the AES HI 3.5 require?

It runs from a 230V single-phase supply and delivers 3.5kW of induction output. This makes it suitable for most UK workshops without needing a three-phase connection.

How does the liquid cooling system work?

The induction unit uses liquid cooling with a 2.5-litre capacity and a 2-metre hose, helping maintain consistent performance during its rated 10-minute operating cycle. Use the specified induction-heater coolant and check the cooling circuit before regular professional use.

Which coils or tips are available for the AES HI 3.5?

The heater uses interchangeable coil heads so the heat pattern can be matched to the job. It is supplied with a U-coil, with additional interchangeable coils and reducers available for different fasteners, components and heating areas. Confirm coil compatibility when ordering accessories.
