The weldcap bump RCB 3/9-12

On demand of variuous professional welders: the weldcap® new with integriated bump cap according to EN812/A1. 

The revolutionary optrel weldcap® RC 3/9-12, that combines the comfort of a baseball cap with the advantages of an automated welding helmet (ADF), is now available in a new extended version: the optrel weldcap® bump RCB 3/9-12. 

Where at normal ADFs the head is only protected in parts, the weldcap® bump now offers a complete protection of the upper head part against painful strikes. Even more, the bump cap gives the weldcap an additional stability and a safety feeling like a full face helmet to the welder, without getting noticeably heavier. 

The easy to remove textile part is made from washable and non-flammable material. You can buy it separately, which means you can turn any existing weldcap® into a weldcap® bump and vice-versa.

Dr. Ramon Hofer Kraner – Head of R&D: „With the weldcap® bump we extended the scope of application of the weldcap® measurably. With the bump cap it's also fitting welders’ needs about higher safety standards“. 

The weldcap hard RCH 3/9-12

Compatible with standard hard hats. Mount the weldcap® hard with a minimum of efforts on your industrial helmet. The cap ’s design accommodates the use of ear muffs.

weldcap series

Radical. Casual.

On the occasion of the leading international Welding & Cutting trade fair in Essen, optrel is presenting the new optrel weldcap® to the world. Since the optrel weldcap® is neither a welding helmet nor a welding mask, optrel had to invent beside the product, also a new name for the product category.

Hence the name says it all, because the weldcap® stands for an auto-darkening welder’s cap that brings together the comfort of a casual cap and the advantages of a full welding helmet. The heart of this innovative product is the optical unit featuring a well-defined nose cut out. Thereby the visual unit is placed closer to the eyes compared to traditional welding helmets, which helps to increase the welder’s line of sight by 2.7 times!

Moreover, because of this, the weight shifts closer to the centre of gravity so that the weldcap® is excellently counterbalanced and the load on the back of the welder’s neck is significantly reduced. The optrel weldcap® weighs only 390 grams, so it is an absolutely lightweight. It relieves the welder of about 200 kg load capacity over a year, when compared to conventional welding helmets.

Darkening levels from 9 to 12 cover the majority of welding applications and with a protection level 3 in its general mode, the welder has a bright an well-lit view of the work-place This feature predestinates the optrel weldcap® for grinding jobs as well. The optrel weldcap® is also completely hygienic. The textile part is robust and easily detachable, and is made of easily-washable, flame retarded fabric.
