Ordering Information Shown with optional TIG Accessories Kit ESAB’s Heliarc 252 and Heliarc 352 are constant current AC/DC welding Power Sources for high quality TIG and MMA welding. They are suitable for welding a wide variety of metals from stainless steel, mild steel and aluminium to exotic and unusual metals. The unique characteristics of the magnetic and solid state circuits provide excellent arc conditions for all TIG welding as well as high alloy stick electrodes. The non-saturating current limiting reactor and electronic feedback control prohibits high current surges therefore reducing spatter on stick electrodes as well as tungsten spitting when TIG welding. The electronic firing circuit uses a voltage regulating circuit which compensates for line voltage variations of +/-10%. √ Square wave AC output gives superior welding with improved cleaning and lack of rectification √ AC wave balance control - allows adjustment from maximum cleaning to maximum penetration √ Arc force control - fine tunes arc for stick welding from soft to a high penetration, digging arc √ 100% solid state design with no mechanical contactor eliminates output drift, lowers maintenance and promotes long life √ Direct connections for TIG Torch and twist lock output cable for maximum convenience √ Adjustable pre and post flow gas control - protects weld area and extends tungsten life √ 1.8m gas hose and water inlet and outlet fittings are factory installed √ Protected against overheating and overcurrent Heliarc 252 AC/DC Power Source 230/460/575Vac, 1-ph, 60Hz 36201 220/400(380-415)Vac, 1-ph, 50Hz CE 36205 Heliarc 352 AC/DC Power Source 230/460/575 Vac, 1-ph, 60Hz 36211 220/400(380-415) Vac, 1-ph, 50Hz CE 36207 Each power source listed above is supplied with 2 male twist lock cable connectors and a 1.8m gas hose. Also required, suitable mains cable, welding cable with appropriate clamp and in most instances a gas regulator.
