Welding aluminum with a pointed electrode increases penetration and stabilizes the arc.

Structural and stainless steels are welded using direct current with the electrode negative pole.

Light alloys are welded using alternating current: when polarity alternation reverses, the flow of electrons from the plate to the electrode cracks the layer of refractory aluminum. On the following alternation, the direct polarity ensures penetration.

TIG welding glossary European CE standards They guarantee a quality of construction, chemical and mechanical characteristics and a level of safety. All Oerlikon generators have CE certification. They impose construction according to European directives.

• Directive 89/336 imposes limitation of emissions of electromagnetic interferences.

• The low voltage directives impose manufacturing, safety and performance rules.

EN 60974-1, device capacities are given according to a welding current delivered at a given duty cycle.

Duty cycle It is defined in the standard. The duty cycle is the duration of continuous use of a device, based on a time of 10 minutes at a temperature of 40°C. A duty cycle of 100 A at 60% means that over a period of 10 minutes, it is possible to weld continuously for 6 minutes, followed by a stop of 4 minutes. A duty cycle of 100 A at 100% means that the source is designed to deliver 100 A continuously.

Pre-gas Used to purge the torch pipes before welding in order to start welding in an atmosphere of protective gas.

Preheating stage Allows positioning on the joint and preheating of the metal to be welded.

Rise ramp Makes it possible to reach the welding current level progressively.

Arc fading Avoids the crater (shrinkage cavity) at the end of the bead when welding stops.

End setting Allows slower cooling of the weld pool and selection of a “lighted arc” welding cycle, which is very useful when welding in position.

CITOSTEP Used to adjust two distinct current levels via a signal from the torch trigger.

Post-gas Protects the weld pool and tungsten electrode during cooling.

Balance Allows welding using alternating current (light alloys) to favour cleaning or penetration.

Pulsed system Avoids collaps of the weld pool during welding of thin thicknesses by time phasing the welding current between a high value (hot time) and a low value (cold time).

Clamping Saves time during spot welding operations by avoiding having to go through the whole welding cycle.

HF arc striking System involving a distant striking of the electric arc without contact between the tungsten electrode and the part to be welded.

Arc striking on contact System involving striking of the electric arc as soon as the torch is raised after contact has been made between the part and the tungsten electrode. This mode is particularly useful when operating in environments that are sensitive to high-frequency interference.

Square waves In alternating current, the square form of current waves ensures excellent arc stability and avoids arc disruption when the current changes direction.

IP protection class The first figure indicates the maximum diameter of an object able to penetrate the device and come in contact with a dangerous part. The second figure indicates the level of protection against falling rain.

Example: IP 23 - the “2” indicates that an object with a diameter greater than 12.5mm may not be introduced into the device - the “3” indicates that it is not damaged by rainfall at an angle of 60°.

CITOTIG AC/DC, inverter technology for TIG welding of With 2 air-cooled models (200 and 250 amps) and 2 water-cooled models (250 and 350 amps), this new CITOTIG AC/DC range handles even the most difficult welding situations. A unique, complete and very user-friendly front panel gives you a precise display of all stages in the welding cycle.

This is a full range of units: single-phase at 200 amps and three-phase beyond with a high duty cycle value, these are water-cooled units that ensure continuous, high-quality work. The front panel groups all functions and offers a very complete welding cycle, digital display of numerous parameters and memorization up to 9 complete welding programs.

Product advantages: • Single-phase power supply for the 200 AC/DC unit with primary consumption lower than 16 A, which makes it totally compatible with maintenance and site work.

• Three-phase power supply for the 250 unit and twin-voltage for the 350, which makes them tools capable of meeting all customer requirements.

• Digital display of welding parameters for enhanced readability • Complete welding cycle with LED display • Processes: TIG DC, AC and MMA • Pulsed function allowing work in position, on tubes and on thin thicknesses • CITOSTEP function with 2 welding current levels and torch trigger call • High-quality arc striking with HF or “contact” mode • Choice of 2T/4T or stapling mode for increased comfort • Modular design (unit/cooler/carriage) for increased autonomy (250 and 350 AC/DC) • Progressive melting with exceptional arc rigidity • “Cleaning/penetration” balance modification on front panel • Alternating current frequency adjustment • Parameters memorization (9 programs) • In AC: balance adjustment: cleaning/penetration, welding with cerium electrodes (pointed) or pure tungsten electrodes (balling adjustment).
