Jasic JT-400P TIG Welder Hire | 400A Pulse TIG Welder Rental from Adlington
The Jasic JT-400P TIG Welder is a high-capability Pulse TIG/MMA welding inverter designed for serious site and fabrication work. Delivering up to 400A welding current, it performs in both TIG and MMA modes with precise control over peak, base and slope current, arc ignition modes (HF or Lift), and optional water-cooled torch setups. Working off 400V AC, it offers a duty cycle around 400A at 50% in TIG mode, efficient output (≈ 85%) and a ~68V no-load voltage for stable arc starting. Built for robustness with strong protection systems, this approx. 90 kg unit in its ~760×360×585 mm form factor is ideal for industrial, heavy engineering, marine, construction and rental use where power, control and weld quality matter.
