With inverter technology, the PROGYS 300 TRI is a 3-phase MMA (SMAW) / TIG (GTAW) welding power source
with exceptional welding performance. Featuring advanced electronics, this product guarantees maximum
productivity, even in harsh environments. Its switchable Voltage Reduction Device (VRD) protects the welder
in hazardous areas (mines, chemical and petrochemical installations, shipyards, etc.).

MMA (SMAW)/TIG LIFT (GTAW)

• MMA (SMAW) : rutile (6013), basic (7018), cellulosic (6010) and aluminium electrodes (up to Ø6 mm)
• Arc gouging with carbon electrodes (up to Ø5 mm)
• TIG (GTAW) process with LIFT arc ignition (Ø1.0 to 3.2 mm)

WELDING AIDS

• Adjustable Hot Start for a better arc ignition.
• Adjustable Arc Force : temporary current increase when welding in
  difficult situations.
• Antisticking : reduce the risk of the electrode sticking to the metal when
  in contact.

HEAVY DUTY

• High duty cycle : 300A @ 60%.
• High no-load voltage (83V) for a good arc dynamic and to facilitate the arc
  ignition for cellulosic (6010) electrodes.
• Optimized cooling thanks to the air-tight ventilation corridor that helps insulating the electronic components from the dust.

WELDER’S PROTECTION

• VRD (Voltage Reduction Device) can be activated via an internal switch to lower no-load voltage down to 20V for safety reasons.
