ESAB LHF 400, a thyristor-controlled welding rectifier with mains voltage compensation, is designed for demanding hand and TIG welding applications. Its advanced features include:

• Constant welding current and arc voltage due to mains voltage compensation.
• Excellent striking and welding properties with an open-circuit voltage and a balanced current boost.
• "Anti-stick" function to reduce the risk of electrode sticking and facilitating root run welding.
• Quiet and spatter-free arc with easily controlled molten pool.
• Suitable for all hand welding electrodes, including basic electrodes.
• TIG welding capable with optional TIG equipment (auxiliary transformer, TIG-AID, gas bottle, gas regulator, TIG torch).
