Steinel Precision Heat Gun Review | HG 350 ESD
The Steinel Precision Heat Gun (HG) 350 is a high quality portable electric heater with a maximum output of 250 watts. It uses two 18650 batteries which are not included in the package.
The Steinel HGs have been used for years by professionals all over the world and they continue to work well today. They are easy to use, reliable and highly efficient. They provide excellent results and are very affordable.
Steinel Hg350 ESD Specifications:
Dimensions: Length – 8.5″, Width – 4.75″, Height – 3.25″
Weight: 2 lbs 9 oz (1 kg)
Maximum Output Power: 250 Watts (max.) or 400 Watts (min.) depending on battery configuration
Battery Type Capacity Wattage Range Max. Continuous Current 0.6A 12V Lithium Ion 1hr 20Min Max.
Power 250W 12.5V Lead Acid 1hr 40Min Max. Power 250W
The Steinel HGs can be equipped with two different types of batteries; a lightweight and powerful 12V Lithium-Ion battery or a more affordable yet heavier 12.5V Lead Acid battery.
Both types of batteries are sold separately and you can choose the one that best suits your working environment.

The Lithium-Ion battery is smaller and much lighter than the Lead Acid battery, however, it is more expensive and offers a shorter working time. The working time for this battery type is about 1 hour and 20 minutes when working at the maximum power of 250W or 400W depending on the temperature of the surface you’re working on.
When working at 200W the working time increases to 1 hour and 40 minutes.
The Lead Acid battery is bigger and heavier but it is much cheaper and offers a longer operating time. The working time for this type of battery is about 1 hour and 40 minutes when working at the maximum power of 250W or 400W depending on the temperature of the surface you’re working on.
When working at 200W the working time increases to 2 hours.
Both types of batteries take about 8 hours to fully recharge. Both batteries are equipped with a convenient socket that allows you to easily spin them when installing the tool.
Both battery types offer overload protection and have been designed to prevent overheating, overcharging or deep discharging.
The Steinel HGs are equipped with two working modes; low and high. The low setting offers a longer working time and is perfect for materials such as wood, plastic or vinyl.
The maximum temperature that can be reached is 250 degrees Celsius or 482 degrees Fahrenheit when working continuously. The high setting is best for materials such as metal, glass or ceramics. The maximum temperature that can be reached is 500 degrees Celsius or 932 degrees Fahrenheit when working continuously.
Both types of batteries can be equipped with a HEPA filter to make the HG into an ESD Safe Heat Gun. The ESD Safe Heat Gun only heats up when the trigger is pressed.
This prevents static electricity from building up and damaging electronic components.
The Steinel HGs are all well made, sturdy and durable heat guns that offer excellent performance and value for money.
Please Note: Steinel HGs are manufactured in Europe. The specifications of the heat guns provided here are approximations only.

The actual product may differ slightly from the specifications provided here.
Steinel HGs are not available in the US. They can be shipped worldwide however, with the exception of countries in the Middle East and Africa.
