Integrated Pulse TIG function controls peak current, background current, pulse frequency, and duty cycle — reduces heat input, minimises distortion on thin-wall SS, and improves weld bead consistency on critical joints.
Fully operational on DG sets and generator-supplied sites between 330VAC and 500VAC — critical for Indian industrial plants, pipeline sites, and shutdown maintenance jobs where grid voltage is unstable.
E6013 and E7018 stick electrode support from Ø1.6mm to Ø3.15mm, covering job material thickness from 1.0mm to 6.0mm — for maintenance, structural repair, and field welding in Stick mode.

APS Welding presents the Portable, Powerful and Productive Stick Electrode TIG Welding Machine. This small wonder weighs only 47 Kg and yet does perform the toughest jobs with ease.
Genesis 400 HD Pulse TIG Welding Machine is a high-performance industrial welding solution designed for precision TIG welding and heavy-duty MMA (Stick) welding applications. Engineered for reliability, accuracy, and consistent output, this machine is ideal for fabrication units, pressure vessel manufacturing, pipeline welding, and critical industrial jobs.
APS Welding Machines manufactures the Genesis 400 HD Pulse TIG using advanced inverter technology to ensure stable arc performance, excellent weld bead quality, and long service life.
The Genesis 400 HD Pulse is a high-performance 400 Amp TIG welding machine designed for precision industrial welding. If you are searching for the latest 400 Amp TIG welding machine price in India, APS Welding offers competitive pricing with advanced pulse technology and reliable output.
The Genesis 400 HDPulseTIG delivers both Pulse TIG and standard DC TIG modes — giving welders full control over heat input on every job.
Pulse TIG alternates between a high peak current (for penetration) and a low background current (for cooling) at a set frequency. This dramatically reduces total heat input — preventing distortion on thin-wall SS and improving weld appearance on critical joints.
Inbuilt HF non-contact arc start — tungsten never touches the job, preventing contamination. Pre-flow and post-flow gas control protect the weld pool and tungsten from oxidation. Compatible with gas-cooled or water-cooled TIG torches.
