TIG AC DC 315 400 Tig Welding Machine

Name: TIG AC DC 315 400 Tig Welding Machine
Brand: Minghua Machines Co., Ltd. (amhweld.com)
Price: 1.00 USD

TIG AC DC 315/ 400 is used for manual welding by direct current and alternating structural steels with coated electrodes (MMA method), as well as quality steels and non-ferrous metals in the inert gas shield (TIG method). In the design and construction of the device the latest developments in the field of PWM technology (pulse width modulation) and IGBT modules (bipolar transistors with an insulated gate) were used, thanks to which the welder is characterized by small size and low weight. The 400 amp TIG welding machine market demands reliable, high-current welders, and our TIG AC DC 315/ 400 model meets those expectations with up to 350 amps output. Don’t hesitate to contact us for a pricing inquiry on our electric welding equipment.
