250 TIG Welder AC/DC
Features
In TIG mode the following functions are available:
- Slope up (from 0 to 10 seconds), Slope down (from 0 to 10 seconds), pre-gas (from 0 to 25 seconds) and post-gas (from 0 to 25 seconds)
- Synergic post-gas
- Possibility to set the initial and final current time
- Base current, current 2, initial and final current both in absolute value and in percentage with respect to the main current
- PULSED TIG ideal for welding on thin thicknesses (frequency adjustable from 0.1 to 5000 Hz), with adjustment of base and
- peak current and duty cycle throughout the frequency range.
- AC process with rounded square wave to reduce arc noise while preserving welding quality
- TIG MIX AC function, which allows you to alternate between AC time and DC time
- ‘TACK’ function, which allows joining two flaps with high penetration, speed, and precision as for the MMA mode, the adjustable parameters are the Hot Start and the Arc Force. There is also the VRD function required for use in high-risk environments. Possibility of remote adjustment by manual controls, by a foot pedal, or by Tig up-down torch.

Guarantees excellent welding dynamics and optimal arc ignition
New inverter welding powersource designed for AC TIG of Aluminium and DC TIG welding of Steel and Stainless. HF (high frequency) or Lift-Arc ignition feature. MMA mode is also available. Thanks to the inverter technology and microprocessors, the welding process is controlled at all times, guaranteeing excellent welding dynamics and optimal arc ignition. The TIG welder series is equipped with a simple and intuitive control panel. With touchscreen technology, welding parameters can be set quickly and easily. With possibilities to set the machine using the two knobs on the panel. 3 user interface modes: Basic, intermediate, and advanced. Ability to memorise up to 99 programs.
Reduced Environmental Impacts
Weldmax’s contact thoughts and cares for the ecological issues and latest technologies which have been designed to reduce the environmental impact.
It reduces the harmonic current emissions according to the international standards.
