MMA/TIG Inverter 1Ph Tecnica 171/S 230V

Main features

• Direct current (DC) MMA and TIG (LIFT strike) electrode inverter welding machine, 150A, with LCD display.
• Strong and raised structure against dust, water and dirt. Compact, light and easy to transport.
• With set welding current display.
• Advanced arc control devices: arc force, hot start, anti-stick.
• Usable electrodes: rutile, basic, stainless steel, cast iron, etc. up to 4 mm.
• Thermostatic, overvoltage, undervoltage, overcurrent protection. Compatible for use with the motor generator (230V, +/-15%). High stability of the welding current in power supply voltage variations.
• Contained consumption thanks to inverter technology.

TIG 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.

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.
• 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.

Protections

• Thermostatic Protection: A heat-sensing system that shuts down the machine if the temperature rises too high, preventing overheating.
• Overvoltage protection: Protects the machine from higher than normal voltage levels, which can damage the electronics or the internal parts of the machine.
• Undervoltage protection: It comes into operation when the supply voltage is too low, thereby helping to maintain the stable operation of the equipment.
• Overcurrent protection: Limits current through the machine to prevent overloading or damage to electrical components.
