Discovery 300T is an inverter-based welding power source complete
with all the functions required for DC TIG and MMA welding with
excellent arc characteristics.
The solidity of the components of this unit makes it a reliable working
companion for workshop and outdoor applications.
This unit is ideal for maintenance, food industry, hydraulics, oil
pipelines and chemical plants.
The parameters preset in the DC TIG pulsed synergic curve simplify
welding by regulation exclusively of the current.
The current is adjustable also from the Up-Down torch.
The simply and intuitive interface allows high precision adjustments
with 50 storable programs.
The wide range of adjustable pulsed frequency in combination with
the complementary parameters (base current and duty cycle) makes it
possible to weld in slow and fast pulsed mode.
The welding modes and procedures available are those indicated in
the table.
