MILLER - WELDCRAFT Weldcraft TIG Torch Kits

Weldcraft TIG Torch Kits

Miller Weldcraft A-150 Series TIG torches are suitable for maintenance & repair operations in aerospace, food & beverage, petrochemical and metalworking applications. These TIG torch kits feature a Diamond Grip head design having contact points for fingers and thumb to ensure a comfortable grip & minimise operator fatigue. They have a flexible neck for ease-of-operation in tough-to-reach areas and ribbed handle for user comfort.

Working Mechanism

• Miller - Weldcraft TIG torches utilise cup, collet body, collet, backcap (including O-ring), torch body, handle, water hose or gas hose, power cable, power cable adapter and international style adapter to keep connections tight for secure & quick installation.
• A high current, low voltage supply or spark is transmitted by the power source to the tungsten or welding electrode. This electrode is attached to the negative terminal of the workpiece, whereas the power source is connected to the positive terminal.
• Tungsten is a non-consumable electrode that provides a highly intense arc to melt base metals and form a welding joint.
• Shielded gases like helium & argon are supplied through the pressure and regulating valves to the welding torch. These gases form a safe shield that does not permit any reactive gases (including oxygen) into the weld zone. The gases also generate plasma, which maximises the heat capacity of the electric arc, thus maximising welding ability.
• There is no need for filler metal for welding thin materials. However, for making thick joints, some filler material is used in the form of rods which are fed manually by the welder into the welding zone.
