GYS has announced the launch of its Gysmi 146 DV (dual voltage) and Gysmi 196 FV (flexible voltage) MMA/TIG inverter-based welding machines for general industrial welding and more.

The welding machines are also said to have applications in site work, the hire market, stadium maintenance and the agricultural industry.

The Gysmi 146 DV is a dual voltage 140A MMA and TIG welding machine that automatically selects between 110V and 230V power supply.

The Gysmi 196 FV is a flexible voltage 160A MMA and 190A TIG welding machine, which is fitted with advanced PFC (power factor correction) enabling it to operate automatically on any voltage between 110-230V.

GYS said this feature automatically compensates for power losses and variations due to generator performance or extra-long extension cables being used.

Both machines have IP23 protection ratings as befits machines intended for outside use.

Both of the single-phase, microprocessor-controlled machines feature good arc characteristics and adjustable hot-start, making the start of MMA welding on thin materials (low hot-start) and difficult-to-weld dirty or oxidised materials (high hot-start) easier.

The machines also feature adjustable arc force for improved penetration and to avoid electrode sticking, and lift arc for easy-to-start TIG welding at the same time preventing tungsten inclusions.

The Gysmi 196FV also has an adjustable downslope for high-quality TIG welding.

High duty-cycle enables the Gysmi 146 DV to be used with 1.6-3.2mm diameter basic electrodes including stainless steel, cast iron and mild steel electrodes, while the Gysmi 196 FV can be used with either rutile or basic 1.6-4.0mm diameter electrodes including mild steel, stainless steel and cast iron electrodes.

Both machines can weld up to 45 x 3.2mm electrodes per hour.

Both machines have easy to operate and read digital control panels and are supplied with a sturdy carry case, electrode holder and welding cable.

In addition, 4m-long TIG torch kits are available as an option.
