The Uni-Tig 180P is an inverter-based DC Tig welding machine with HF arc ignition and pulse capability. Produced using the latest in IGBT technology this low cost and portable machine is reliable, robust and stacked with all the functions you expect from a professional DC Tig welder.

The HF arc ignition provides pre gas and instant arc ignition with the press of the torch switch leaving no tungsten inclusion and no contamination of the tungsten electrode. The Down Slope, Post Gas functions combined with the 2/4T trigger function gives you control of the welder allowing you to control the start and finish of the weld process at a professional level.

The addition of 2 pulse frequency options gives you the added capability to control better the heat input into the work, control better penetration and help control distortion. Combining the functions of the Uni-Tig 180P ensures comprehensive control of the welding parameters when welding all DC weld-able materials giving a remarkably smooth arc producing high quality Tig welds.

The DC MMA welding capability delivers a smooth and stable arc allowing easy welding with electrodes obtaining high quality welds including cast Iron, stainless and low hydrogen.

The Uni-Tig180P is a professional machine that is suitable for multiple applications; stainless steel fabrication, light industrial use, site welding, repair and maintenance applications. It is supplied with MMA arc lead, argon regulator and SR17-4m tig torch
