TIG (HF/LIFT), PULSE TIG-EASY PULSE and MMA, Infinity TIG 225 DC inverter welding machine,1ph,VRD, Telwin

In alternating current, TIG AC allows you to weld aluminium and its alloys (AlSi, AlMg), while in direct current, TIG DC allows you to weld steel (carbon, stainless, low alloy and high alloy) and heavy metals (copper, nickel, titanium and their alloys).

• Microprocessor controlled, TIG (high frequency HF or LIFT striking), PULSE TIG-EASY PULSE and MMA inverter welding machine in direct current (DC).
  • Pulse TIG: the welding current changes periodically between a higher and a lower value. This cyclic current change allows finer control of heat input, which is beneficial when welding thin or heat-sensitive materials as it reduces the risk of overheating the material and minimizes distortion.
  • Easy Pulse: simplifies the setting of pulsing parameters. It allows the welder to easily set the desired pulse frequency and amperage, thus optimizing the welding process for different materials and welding tasks.
• Supplied with accessories for TIG welding.          
• Adjustment of multiple parameters of the TIG welding torch. 2/4 stroke operation.
  • 2-stroke for quick and easy welding tasks, which allows an immediate stop when the trigger is released.
  • 4-stroke for longer, continuous welding jobs, where the process can be stopped with the second activation of the trigger, thus reducing user fatigue and improving the quality of the seam.     
• Set up for remote control.          
• MMA welding: rutile and basic electrodes up to 4mm.
• VRD device for greater safety. Enabling/disabling the “Voltage Reduction Device” for a safe start at low voltage.
• Contained consumption thanks to inverter technology.
• Adjustment of multiple parameters of the TIG welding curve.
• TIG mode with 2/4T sequence.
• Remote control connector.
• MMA: adjustable arc force and hot start, anti-stick.
• Complete with TIG welding accessories.

Main characteristics

TIG
- AC/DC current adjustment and character parameters. This type of process allows welding of metals such as aluminium and magnesium that form a protective and insulating oxide on their surfaceTIG DC welding is suitable for all low- and high-carbon steels and the heavy metals, copper, nickel, titanium and their alloys.
- HF/LIFT strike. 

• HF strike: The electric arc is struck without contact between the tungsten electrode and the piece being welded, by means of a spark generated by a high frequency device. This strike mode does not entail either tungsten inclusions in the weld pool or electrode wear and gives an easy start in all welding positions.
• LIFT strike: 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.

- Continuous/pulse operation.
- Selection modes 2T, 4T, 4T Bi-level, 2T Spot, 4T Spot, Thin Spot.
- Connection and setting of the water cooling unit (G.R.A.) (R.A. versions only).

MMA
- Current, Arc force and Hot Start settings:

• The Arc Force function 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.
• Thanks to the Hot Start function, 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 protection 

• The Anti-Stick function 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

- Average value continuous/pulse operation (if planned).
- VRD device: Enabling/disabling the “Voltage Reduction Device” for a safe start at low voltage.

Other
- Display of parameters and selected modes.
- Saving and referencing possible of customised programs (JOB).
- Facilitated referencing of default parameters (DEFAULT) and simplified default mode (EASY).

Protection
- Thermostatic protection: A heat-sensing system that shuts down the machine if the temperature rises too high, preventing overheating.
- Protection against irregular voltage (power supply voltage too high or too low).
- Protection against accidental short-circuits caused by contact between torch and earth.
- Anti-stick (MMA).
-Protection against overheating and insufficient pressure on the water cooling circuit of the torch (R.A. versions only).
