TIG AC DC 200/ 250 Tig Welding Machine

Name: TIG AC DC 200/ 250 Tig Welding Machine
Brand: Minghua Machines Co., Ltd. (amhweld.com)
Price: 1.00 USD

The welding machine 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.

Features

This production line has two types, screw type, and hydraulic type.

The daily production of spiral coated powder electrode production line is generally about 10, 16 tons. It has the advantages of simple structure, easy manufacturing, convenient maintenance, no need to stop feeding, continuous production, so it has high production efficiency, and the coating has the advantages of uniform thickness, smooth, dense, stable quality, and can also make the welding rod press coating, transmission, grinding head, grinding tail, printing, drying and packaging processes to achieve complete intelligence or automation. It is the main production method in the current production of welding rods.
Welding rod hydraulic powder coating machine is suitable for mass production of Ø2.5 (1.6) ~ 5.0mm common acid, alkaline electrode and special high-performance electrode surface coating.The machine adopts mechanical, hydraulic and electrical joint control operation. And according to the specification of welding rod, process requirements, by controlling the hand wheel stepless adjustment flux delivery.
The welding rod hydraulic powder machine series adopts the welding charge method and selects the first or second feeding procedure respectively through the button on the semi-automatic platform. Welding rod hydraulic coating machine series
The coating die head is 45°. The powder channel adopts the replaceable sleeve and detachable mechanism, which has the advantages of small deflection torque, strong stiffness and high precision. The solder coating is dense,smooth surface, eccentric stability.
