The Lahti Work Trousers are premium flame-retardant trousers designed to offer superior protection even in the harshest welding environments.

They are comfortable to wear due to their elastic waist and have wider belt loops to fit the Kemppi Fresh Air system leather belt. The trousers are easily adjustable; the legs can be extended by an extra 6 cm, and the width of the legs can be adjusted with flame-retardant Velcro.

The trousers have many multifunctional pockets, such as the calliper and torch handle pockets, multitool pockets, and pockets for knee pads (sold separately; see knee protectors Kotka). Made from 80% cotton, 19% polyester and 1% carbon fibre.

The trousers are certified with welding standards EN ISO 11611, EN ISO 11612, and electrostatic EN ISO 1149.

Available in sizes XS-5XL.

Popular Products FAQs

A buyer's guide to the kinds of welding, cutting and protective equipment people look at most, and what to check before choosing.

What does duty cycle mean when I compare welders and cutters?

Duty cycle is the share of a ten-minute period that a machine can run at a stated output before it must cool down, usually quoted at a set ambient temperature. A machine may be rated at a higher duty cycle at lower output and a lower one at full output, so the figure only means something alongside the current it applies to.

If the thermal protection cuts in, leave the machine running its fan and wait for it to reset. When comparing machines, look at the duty cycle at the current you will actually use, not just the headline maximum, and check the data plate and manual.

How do I check a welder will run from my electrical supply?

Look at the machine's data plate and manual for the supply voltage, the effective and maximum current it draws and the fuse or breaker size it recommends. Then check that the socket, cable and circuit protection at your workshop suit those figures.

Do not assume that a plug fitting means the circuit can cope. If you plan to run the machine from a generator, check the maker's guidance on generator output and voltage quality. Have a competent electrician check the circuit if you are unsure.

Is a powered air respirator better than a standard welding helmet for fume?

A standard welding helmet protects the eyes and face but does not by itself protect your lungs. Capturing fume at source is the most effective control, and where that cannot control exposure enough, or is not practical such as outdoors, respiratory protective equipment is needed.

Powered or supplied-air respirators are often a good choice for arc welders. Particulate filters do not protect against welding gases, and the wearer needs face fit testing where the equipment requires it. Choose the system after a risk assessment.

Which type of welding glove should I choose?

Welding gloves are made in different types. Some give higher heat and wear protection with less feel and are for general welding and cutting. Others give better dexterity with lower protection, and these are generally recommended for TIG welding where fine control matters.

Check the marking and the maker's description of what the glove is intended for, because a heavy-duty glove may not be intended for TIG. Also consider cuff length, lining and fit, and replace gloves that are worn, thin or burnt through.
