  • Welding Current

    250

    Suitable for professional use on thick metals, such as steel or cast iron constructions.

  • Duty Cycle

    The Duty Cycle is the portion of a ten-minute period that a welding machine can operate continuously at maximum Amperes before it needs to stop and cool down.

    2.

    For example, a welding machine with a maximum Amperage of 200 A and a Duty Cycle of 30% can operate continuously at 200 A for 3 minutes before it needs to stop.

  • Power Supply Voltage

    230

    It is the supply voltage that the machine requires from the electrical grid.

  • Power

    12.3

    Affects the power consumption of the machine and determines if it can be supported by the electrical network you are using.

Description

Description

Capabilities

Inverter welding machine MMA / TIG from the manufacturer Imperia, where inverter technology enhances the performance and durability of the machine and helps reduce its weight. The MMA electrode method creates thick and strong welds without the need for an external gas supply, making it ideal for welding outside the workshop. While the TIG method is suitable for slow welding on aluminum and stainless steel that requires detailed work and does not create splashes. It can operate continuously for 6 minutes at 250A before needing to stop to cool down. Therefore, due to the maximum Amps it supports, it melts thicker wires more easily and creates thicker welds with fewer passes. Its weight reaches 9.6kg.

Features

  • Welding methods: MMA / TIG
  • Performance: 250A
  • Power: 12.3kVA
  • Voltage: 230V
  • Electrode: 5mm
  • Weight: 12.3Kg
  • Duty cycle: 40% 40°C, 100% 25°C

Package Contents

  • Electrode holder with 3m cable
  • Ground clamp with 3m cable
  • Suspension strap

Additional Features

Inverter
Yes

Inverter


New technology welding. Very good in terms of performance, durability, and weight, but with a high cost of repair in case of damage. They have automation for better and safer work. If connected to a generator, it is recommended to choose one with 8kVA or more.
IGBT
Yes

IGBT


Allows the conversion of direct current (DC) voltage to alternating current (AC) or the output of direct current at a higher or lower intensity.
VRD
No
with Voltage Stabilizer
No
for Generator with AVR
Yes

for Generator with AVR


Suitable for generator with AVR voltage stabilizer.

Features

Hot Start
Yes

Hot Start


Temporarily increases the current intensity at the moment of welding initiation.
Anti Stick
Yes

Anti Stick


Cuts off the current if the electrode sticks to the metal, to prevent it from burning.
Arc Force
Yes

Arc Force


Helps in the stability of the arc during welding.
2T Operation

    In tests with electrode 2.5 and 3.25 (I didn't have 4s or 5s), the gas welding was very good and powerful. Only time will tell. After 4-5 years of use, even with heavy-duty welding, the tool is solid and worth its money
