Technomig 260 Dual Synergic 230V multiprocess welding machine

• This welding machine is a 250A source of current for arc welding, made specifically for MAG welding carbon steel or weak alloys with CO2 protective gas or Argon/CO2 mixes, using tubular full or core electrode wires.
• It is also ideal for MIG welding stainless steel with Argon gas containing + 1-2% oxygen and aluminium and CuSi3, CuAl8 (brazing) with Argon gas, using electrode wires that are suitable for the workpiece to be welded.
• Suitable core wires can be used without Flux protection gas, adapting torch polarity according to the indications of the wire producer.
• It is particularly suitable for light metalwork fabrication and in body shops, for welding galvanized plates, high stress stainless steel and aluminium. SYNERGIC operation ensures fast and easy welding parameter setting, always guaranteeing high arc control and welding quality (OneTouch Technology).
• The welding machine can be used for TIG welding in direct current (DC), with arc striking upon contact (LIFT ARC mode). It welds all types of steel (carbon, low- and high-alloy) and heavy metals (copper, nickel, titanium and their alloys) with a gas shield of pure (99.9%) Ar or, for special uses, with an Argon/Helium mix.
• It can also be used for MMA electrode welding in direct current (DC) using coated electrodes (rutile, acid, basic).

Key features

• Technomig 260 Dual Synergic is confirmed as the perfect solution for a wide range of applications, from maintenance to installation and interventions in body shops, because of its flexibility and the different materials it can weld (steel, stainless steel, aluminium) or braze weld (galvanized sheet).
• The fast SYNERGIC adjustment of the welding parameters thanks to the "ONE TOUCH" technology, makes the product very easy to use. Just set the material thickness and start welding: the intelligent and automatic control of the arc, moment by moment, maintains high welding performance in all working conditions, with different materials and/or gases.
• 29 synergy curves available.
• Max. spool 15kg (200/300mm)
• The operator can also intervene manually along the arc length: this adjustment means the weld seam can be modified according to the welder's style.
• ATC (Advanced Thermal Control) to facilitate welding on thin materials.
• Lightweight and very compact, Technomig can be moved around easily in all intervention areas, both indoors and outdoors.
• Polarity reversal for NO GAS/Flux, MIG-MAG/BRAZING welding.
• Visualization on LCD display of voltage, current, welding speed.
• Regulation of: wire speed up slope, electronic reactance, burn-back time, post-gas.
• Choice of 2T/4T and spot operation.
• MMA: Advanced arc control devices: arc force, hot start, anti-stick.
• VRD device for greater safety. Enabling/disabling the “Voltage Reduction Device” for a safe start at low voltage. The VRD function allows to decrease the output voltage, increasing the operator’s safety when working in humid or particularly dusty environments.
• Thermostatic, overvoltage, undervoltage, overcurrent, motorgenerator (+/- 15%) protections.
• Complete with MIG torch (MT25, 3m), work clamp and cable.

MIG-MAG
- Synergic (automatic) or manual operation
- 29 pre-set synergic curves
- Wire speed, welding voltage and welding current shown on an LCD screen
- Polarity change for GAS MIG-MAG/BRAZING welding or NO GAS/FLUX
- Setting the metric or UK system
- Selection of 2T/4T time operation and spot

• 2T: welding begins when the torch push-button is pressed and ends when the push-button is released.
• 4T: welding begins when the torch push-button is pressed and released, and ends only when the torch push-button is pressed and released a second time. This mode is useful for long welding operations.
• Spot welding mode: used for MIG/MAG spot welding with control of welding duration.

Adjustments

- Electronic reactance: Adjusting the reactance during MIG/MAG welding allows you to fine-tune the inductance of the welding circuit. By adjusting the reactance, the welder can optimize the behavior of the welding arc when welding different material thicknesses and types, improving the quality of welding and facilitating the welding process.
- Wire upslope: This setting allows you to gradually increase the speed of the welding wire at the beginning of welding. This helps reduce welding errors such as excessive penetration or spatter when the arc is struck, ensuring a smoother start and transition in the welding process.
- Wire burnback time setting: This setting controls the amount of time the wire can "burn back" after welding is complete before it automatically stops. Setting the proper burnback time ensures that the wire does not burn back too short, making it easier to start the next welding cycle.
- Post-gas setting: This function controls the amount of time that shielding gas continues to flow after welding is completed to protect the still-hot weld from airborne contaminants until it cools down.

TIG
- Start LIFT: The electric arc is struck by moving the tungsten electrode away from the piece to be welded. This strike mode causes less electrical-radiation disturbance and reduces tungsten inclusions and electrode wear to a minimum.

MMA
- Arc force: This helps maintain a stable arc even in difficult conditions, such as dense welds. With the Arc Force function, the inverter automatically adjusts the current depending on the length of the arc. If the arc accidentally touches the workpiece, the current increases, so it does not stick. If the two are too far apart, the current will be reduced and the arc will not extinguish.
- Hot start: it helps to ignite the arc more easily by automatically increasing the current at the beginning of the welding process. This can be especially useful for difficult-to-ignite electrodes. Facilitates arc ignition for materials that are too cold or too thick.
- Anti-stick: prevents the electrode from sticking to the workpiece, reducing the current connected to the electrode when it detects sticking. This makes it easier to remove the electrode and reduces the risk of overheating.
- VRD device for greater safety. Enabling/disabling the “Voltage Reduction Device” for a safe start at low voltage.
- Indication of recommended electrode diameter based on welding current.
- Wire speed and welding current shown on an LCD screen.

PROTECTION
- Thermostatic safeguard: A heat-sensing system that shuts down the machine if the temperature rises too high, preventing overheating.
- Protection against accidental short-circuits caused by contact between torch and earth
- Protection against irregular voltage (power supply voltage too high or too low)
- Anti-stick (MMA).
