This regulator is to be used for propane gas cylinders with German cylinder valves or propane gas cylinders with identical valves. The regulator itself does not have a seal, it has a special sealing surface with a moulded bead which presses against the rubber seal in the cylinder valve. When the regulator is screwed onto the valve of the propane cylinder it is sealed. The use of an additional seal is not permitted!

Silver brazing alloy Rolot 606 (art. no. 35606) is an alloy used for soldering jewellery, especially gold and silver. It is characterised by a lower melting point and enables a strong and durable connection between the jewellery parts without damaging the base material. It is characterised by high strength and corrosion resistance and is well suited for forging projects where a permanent bond is required.

The working temperature. Soft soldering: in the range from 120°C to 450°C | Hard soldering: in the range from 450°C to 1100°C | Oxyfuel welding: over 1100°C.

When the soldering temperature is reached, flux pastes containing solder immediately wet the contact surfaces with solder, also known as "tinning". This effect also serves as a clear indicator that the working temperature has been reached.

Socket joints can be soldered in any position. The capillary gap ensures that the solder spreads evenly between the fitting and pipe when the soldering temperature is reached. The pipes/fittings to be processed must have a high fitting accuracy to ensure the capillary effect for the flow of the solder into the soldering gap.

The ROTHENBERGER fitting solder no. 3 (art. no. 045256E). It consists of the elements copper and tin (7%/93%) and is suitable for use in drinking water applications. The ROTHENBERGER fitting soldering paste or the soft soldering set, consisting of fitting soldering paste, fitting solder and cleaning fleece, should be used in addition. When you purchase our RoFix, you have a ready-to-use soldering set consisting of a soldering device, Multigas, fitting solder, soldering paste and cleaning fleece.

The replacement tip set art. no. 35125 contains 4 replacement tips that can be used for the following applications:

• Catalytic head for precise and delicate soldering work
• Needle tip for fine soldering work
• Chisel and bevelled tip for normal electrical work
• Knife for polystyrene cutting

The replacement tips are suitable for the RoPen 1300 (item no. 35115), the Micropen Set 1300 (item no. 35120) and for the Hot Pen Piezo Set (item no. 36060).

Our 0.9 mm cored wire is manufactured for the DIY sector and, according to the manufacturer's instructions, can be welded to both positive and negative poles using DIY welding equipment. Several factors are decisive for the polarity of the special cored wire electrodes. The welding machine itself, which must be designed to reverse the polarity of the wire electrode to negative. This is stated in the operating instructions and always applies to so-called "gas-no gas devices". In this case, the polarity is reversed by reconnecting/screwing the welding cable or switching over using a switch. Flux-cored wire and many MIG / MAG DIY welding machines very often do not have this option. Furthermore, the polarity depends on the wire filler and the specified welding technology, which may also specify the use of shielding gas. In this case, the electrodes are usually wire electrodes for professional use.

The flux in the Rolot 606 has corrosive properties on stainless steel and must be removed. The visible flux residue (similar to the slag in electric welding) should be removed mechanically and treated with a pickling agent, similar to the gas-shielded welding process, or a weak organic acid (citric acid, acetic acid). Please always treat with plenty of water after this treatment; in most cases, unsightly discolouration of the material can be largely neutralised in this way. You can also minimise the residue of the flux by mechanically removing parts of the flux coating, before using the soldering rod. This depends on the nature of the material and must be checked beforehand by means of a test soldering, during which the optimum flame setting should also be determined.

Our appliances are equipped with a reliable piezo ignition system that ignites the fuel gas immediately after the gas supply is opened. The gas valve should only be opened slightly for the ignition process to prevent the burner flame from being blown out again, immediately after ignition due to excessive gas flow. Repeated operation of the ignition mechanism until the burner flame ignites is not normal with an intact appliance. It can have various causes that are difficult to determine via "remote diagnosis". The piezo ignition mechanism can, for example, be impaired by moisture, hairline cracks in the insulation due to mechanical effects such as transport damage, dropping, etc. An ignition spark may still be visible, but this is ultimately not sufficient to ignite the gas.

The "gas nozzle protects contact tip" is a protective device used during welding to protect the contact tip from spatter, contamination and damage. It guides the shielding gas around the welding point and ensures a stable welding process.

After using an inverter for welding or similar applications, the appliance should not be disconnected from the mains immediately. Instead, give the inverter enough time to cool down before unplugging it. This will extend the service life of the inverter and prevent possible damage due to excessive heat build-up.

The operational readiness of our socket fusion units is signalled by a green or red light. A red light means that the device is receiving power, while a green light indicates that the device is ready for operation.

Maxigas 400 enables flame temperatures of up to 2,200 °C when used in soldering equipment. Maxigas 400 guarantees a consistently high burning performance. Maxigas 400 is of a higher quality than Multigas 300 and guarantees a better working result in ROTHENBERGER small oxyfuel welding equipment.

In comparison: Multigas 300 (flame temperatures up to 1,900 °C) Maxigas 400 (flame temperatures up to 2,200 °C)

The C200 super gas piercing cartridge may be used with any appliance in the direct butane pressure category in accordance with EN 521. The cartridge complies with the EN 417 standard.

The Maxigas, Multigas and Topgas screw-in cartridges may only be used with corresponding cartridge devices with a 7/16" screw connection that correspond to the direct pressure category of the butane/propane mixture. The cartridges all comply with the EN 417 standard.

The composition of the argon in our 1-litre disposable bottle (item no. 35775) is "Argon 4.6", which means that it has a purity level of 99.996%. After consultation with our supplier, an even higher quality than argon 4.6 is usually filled. However, we cannot guarantee that this is always the case.

The technical data of the bottle are as follows: tare 1140g, volume 950 cc, pressure 60 bar at 20°C, content 60 litres, test pressure PH 165 bar. With regard to gas consumption, we would like to inform you that, according to our guidelines, a 1 litre disposable cylinder containing 60 litres of argon can be used for approximately 8 minutes of uninterrupted welding with a 0.8 mm wire electrode (or approximately 10 minutes with a 0.6 mm wire electrode) under optimum conditions when using a MIG/MAG unit. With the TIG process, taking into account the setting of the gas quantity according to the amperage (with a DIY device with a welding current of 200 A), you can weld continuously for about 10 minutes. Please note that this is only an estimate and the actual gas consumption may vary depending on individual conditions. In addition, older cylinders, possibly 7-8 years old, may experience some shrinkage due to gas leakage, which may result in a reduced fill quantity.

Our RoTurbo 12000 / 19000 / 35000 / 35000SA gas-fuelled heaters are always equipped with a mains-independent thermal safety element. This safety device prevents the further supply of gas after the burner flame has gone out, regardless of whether this is due to a defect or the operator deliberately switching off the gas supply (cylinder valve). You must, therefore, restart the burner operation as described every time the gas supply/bottle valve is switched off. No gas will flow into the appliance without this starting process. If, contrary to expectations, you hear a noise entering the appliance when the gas supply / cylinder valve is opened, this would be due to a defect in the safety device. In this case, the appliance must not be operated. When this happens, please contact your dealer, who will get in touch with us for further processing.
