KEMPPI Gamma GTH3 PFA/SFA/XFA Welding Helmet

Introduction

About Gamma personal protective equipment

Gamma product models are personal protective equipment (PPE) for welders and fabrication personnel. They are designed for arc welding (MMA, MIG/MAG, TIG), grinding, gouging and plasma cutting.
Gamma welding helmets provide the users with protection for the eyes and face. They combine a flip-up welding visor with a protective grinding visor and include either an auto-darkening filter (ADF) or a passive welding filter lens.

Gamma GTH3 models also protect the user’s respiratory system when used together with a compatible powered filter unit (PFU 210e) or supplied air unit (RSA 230). Gamma GTH3 models offer the highest level of respiratory protection: TH3 classification with PFU 210e, and 3B classification with RSA 230.
The following table introduces the features of the Gamma product models.

Safety

Gamma personal protective equipment helps protect the wearer’s eyes from harmful radiation including visible light and ultra-violet/infra-red radiation resulting from certain welding processes.

Warning:

• It is strictly forbidden to use any other than Kemp-pi branded filters or other parts or accessories with Kemppi’s personal protection equipment. If you do not respect this safety regulation, serious damage for your health may occur.

Warning:

• We recommend a usage period of 5 years. The period of use depends on various factors such as use, cleaning, storage and maintenance. Inspect the helmet before each use. Replace damaged or worn parts. Never use a scratched or damaged welding filter and ocular. · Use all adjustment features for maximum protection. · Never weld with the welding visor up or without the welding filter.

Warning:

• If the auto-darkening filter (ADF) does not darken when the arc ignites, stop welding immediately. Inspect the ADF and its power supply. Change if necessary.
• Always use welding filters together with suitable protection plates. · Never use welding filter without inner protection plates. · Materials which may come into contact with the wearer’s skin may cause allergic reactions to susceptible individuals.
• Only operate this product within the temperature range -5…+55 °C.
• The product is not intended for use in environments with a risk of explosion.
• The helmet does not protect against explosive devices or corrosive liquids.
• The helmet is not suitable for laser welding and oxyacetylene welding/cutting processes.
• Set and tighten the face seal properly. If the face seal is not tight, the respiratory protection may not reach the best level.
• The helmet gives designed protection against high speed particles only at room temperature (EN175 B) and only when all helmet components are properly attached, as described in the manual.
• If the symbols of the marking are not common to different parts of the protection equipment, the lower protection level shall be assigned to the complete protection equipment.
• If protection against high speed particles at extremes of temperature is required then the selected eye-protector should be marked with the letter T immediately after the impact letter, i.e. FT, BT or AT. If the impact letter is not followed by the letter T then the eye protector shall only be used against high speed particles at room temperature.

When helmet is worn over any spectacles, they may transmit the impact of high speed particles, thus creating a hazard to the wearer.
