W+ - Pink: The new generation of tungsten electrodes

What makes the W+ - Pink tungsten electrode so special?

In TIG welding (tungsten inert gas welding), the MMA is the centrepiece of the torch The heart of the Torch. It transmits the current and generates the arc Arc that melts the workpiece. The W+ - Pink is a modern high-performance electrode that has been specially developed to meet high Fulfil high demands in industry and trade.

In contrast to pure tungsten (green), which is used almost exclusively for aluminium Aluminium on alternating current, the W+ is an electrode doped with rare earths an MMA doped with rare earths. This composition ensures for:

• Excellent ignition behaviour (even with re-ignition).

• A high current carrying capacity.

• A significantly longer service life compared to Standard MMAs.

Technical excellence in detail

The base material tungsten has the highest melting point of all metals Metals (over 3400 °C). This makes it the ideal material for non-melting MMAs. The W+ - Pink optimises this Property thanks to its oxide mixture. Regardless of whether you are working with 1.6 mm, 2.4 mm or 3.2 mm diameter - the standard length of 175 mm (or 175 for short) fits all standard TIG torches.

Areas of application: A real all-rounder

The W+ - Pink can be used universally. It shows its strengths especially where precision is required.

TIG welding of steel and stainless steel

The main area of application for this MMA is direct current welding (DC) welding of steel and stainless steel. Here it ensures a very smooth arc Arc and deep penetration. If you process stainless steel - for example in railing construction or in the food industry - the W+ Pink guarantees a clean, low-tarnish weld seam.

TIG welding of aluminium

Although pure tungsten electrodes have traditionally been used for aluminium (AC welding) used for aluminium (AC welding), modern inverter welding machines and doped electrodes MMAs such as the W+ Pink often produce excellent results here too. The Arc remains stable and the formation of domes can be controlled.

The TIG process and accessories

TIG welding (known as TIG or Tungsten Inert Gas ) is regarded as the "royal process". It requires practice, but offers the most beautiful joining of metals.

For the welding process to be successful, an inert gas (shielding gas) is is absolutely essential. Argon is usually used. The shielding gas protects the molten pool and the hot MMA from the atmosphere (oxygen) to prevent oxidation (oxygen) to prevent oxidation.

The right welding equipment is also crucial. For the W+ Pink all modern DC and AC/DC inverters are suitable. Make sure that your welding machine has HF ignition to fully utilise the potential of the electrode Fully utilise the potential of the MMA.

Frequently asked questions (FAQ) about TIG welding and MMA electrodes

Here we answer the most important questions that our customers often to help you with selection and application.

Can aluminium, stainless steel and steel be TIG welded?

Yes, the TIG process is one of the most versatile processes of all. It can be used to join almost all fusible metals.

• Steel and stainless steel: are welded with direct current (DC). Here the MMA is at the negative pole. This is the most common application for the W+ Pink.

• Aluminium: Welded with alternating current (AC) to break up the oxide layer on the metal on the metal. The process is suitable for Root seams, thin sheets and visible seams, as it works very cleanly and and produces hardly any spatter.

Which MMA electrodes do I use for TIG welding stainless steel?

For stainless steel (chrome-nickel steels), you need an MMA that high temperatures and is easy to ignite.

• The best choice: doped MMA such as the W+ Pink, Gold (WL15) or grey (WC20). They offer a long service life and do not contaminate the weld pool.

• Obsolete: Although red MMAs (WT20) are technically good, they are radioactive radioactive and harmful to health due to the thorium. The W+ Pink is the modern, radiation-free alternative with often better welding properties Welding properties.

What do I need to bear in mind when TIG welding?

TIG welding requires cleanliness and precision.

1. Cleanliness: The workpiece must be absolutely free of grease, oil and rust.

2. Grinding of the MMA: The tungsten electrode must be sharpened in the longitudinal (axial) direction (axial) direction. Cross grinding leads to an unstable arc unstable arc.

3. Gas flow: Too little gas leads to pores (Swiss cheese), too much gas can create turbulence that draws oxygen into the weld seam.

4. Safety: Always wear full protective equipment, as the UV radiation is very intense during TIG.

Which devices are suitable for TIG/TIG welding?

The choice of device depends on the material:

• DC devices (direct current): These are ideal if you are only welding steel, Stainless steel, copper or titanium.

• AC/DC devices (universal current): If you also want to weld aluminium, aluminium, an AC/DC device is absolutely essential, as only alternating current can can break down the hard oxide layer of the aluminium. Pay attention to Functions such as HF ignition (high frequency), gas pre-flow and post-flow time and pulse functions for thin sheets.

Tungsten electrodes: Which colour should you choose?

The colour coding provides information about the oxide additives in the tungsten.

• Pink (W+): The modern all-rounder. Excellent for steel/stainless steel, radiation-free, long service life. Often replaces red.

• Gold (WL15): Universal (AC/DC), very popular, lathanalloyed.

• Grey (WC20): With cerium oxide, very good for low amperage and Robot applications.

• Green (WP): Pure tungsten. Only for aluminium (AC) on old Transformer devices. Soft arc, forms a spherical cap.

• Red (WT20): Contains thorium (radioactive!). Should be avoided for Avoided for health reasons and replaced by types such as pink or gold pink or gold.
