Concern ESAB welders released budget line Buddy:

• Buddy Arc 145 for manual arc welding (MMA);
• Buddy Arc 180 and Buddy Arc 200 for manual arc welding and TIG welding with tungsten electrode (TIG) with the ignition of the arc margin;
• Buddy Tig 160 for TIG welding with HF ignition of the arc (TIG HF) and MMA-welding.

The models differ in a simple control, overload protection, safe housing, designed for harsh environments, as well as efficient inverter technology-based IGBT (bipolar transistors with insulated gate).

The devices support hot-start function (Hot start), anti-sticking electrode (Anti stick), stabilization of the arc (Arc Force). You can manually welding with direct current iron, alloyed and unalloyed steel and other metals.

Buddy Arc Models 180 and 200, Buddy Tig 160 allow you to weld stainless steel and tungsten low-carbon steels with a filler material or without it (in the presence of the burner, regulator and gas cylinder).

Buddy Tig 160 - Mobile phone for professional TIG-welding. The high-frequency arc ignition (TIG HF) is carried out without touching the product tungsten electrode, which prevents the likelihood of tungsten in the seam. Chance of a two-or four-stroke mode including the burner.
