Specially designed for ARC and MIG welding operations and switchable between shades 10 and 11 the Defender F offers all the protection delivered by the standard Defender series in a simpler, less expensive, more focused package. For reliable performance in a value-for-money package look no further than the 4000F.
A basic variable shade (9 to 13) version of the Defender is also available but please note that this product is different from the standard Arc Defender welding helmet and is not sold in all countries.
Incorporating the same UV/IR filters as the standard Defender series but with different LCD
and control technology, the Defender Basic is ideal for general industrial, farm and hobby use.
Specially modeled around the human form and carefully balanced for optimum comfort, the lighter, tougher 4000 series shell is comfortable even after extended periods of wear.
Servore designers have emphasized strength, durability and user comfort to maximise
safety and protection and because the Defender 4000F is more comfortable you can weld better for longer. As with all Defender series helmets you have reliability, performance, and better protection built in.
Like all Defender series helmet shells, the 4000F is made from a special kind of heat resistant nylon. Nylon is tough, impact resistant and light ensuring effective protection under even harsh conditions.
Regardless of what you want in a welding helmet, there is a product in the Servore range that delivers. From basic, reliable protection in the SF-11 and 4000 Basic/F models to the top of the range 5000 Auto Lift, Servore offers the protection and value you need. Better Protection.

Auto On / Auto Off 'Wear and Weld' Technology
Servore's auto on / auto off technology means there is no need remember to
switch the helmet on, just 'wear and weld'. Safe, convenient and easy to
use the auto lift uses both power from the batteries and the solar cells to
automatically power on and react immediately. Batteries typically last
years and are easily replaced when necessary.
Dual Power with patented Servore Inner Sense Technology
Servore’s patented Inner Sense auto sensing technology reliably detects the arc even at
very low power and under difficult conditions eliminating the need for the additional sensors that many systems need. Powered by both replaceable batteries and solar cells, the Inner Sense system brings improved reliability and performance to Servore auto darkening helmets without the need for additional external sensors.
Full Time Protection
With reliable, full time protection against harmful UV/IR radiation you can weld more comfortably with less eye strain and increased confidence. Don’t trust your future to anything less than proven Servore protection. Better Protection.
All Servore products incorporate the same high quality UV/IR filters so you can be sure that you are getting the protection you need all the time. Don’t compromise on quality or cost where safety is concerned. You need it. You deserve it. You need Better Protection.
Shade control
Like all Servore adjustable shade control systems, the 5000 Pro offers complete control over the dark state when welding and is adjustable from shades 9 to 13.
