That means that the amount of time it CONTROL takes the AC wave to complete a full cycle switch from positive (+) to negative (-) can be adjusted from 20Hz (20 times per second) to 250Hz.
  • Page 25 RAZOR TIG 200 ACDC OPERATING MANUAL Razor AC TIG Welding - AC Wave Balance Control 32OAC/DC TIG-MMA AC TIG Welding Further Details AC (alternating current) enables us to TIG weld non ferrous alloys like Aluminium, Magnesium and Aluminium Alloys. These materials have an insulating surface oxide layer that melts at a higher temperature than the base metal making it difficult to weld the base metal if the oxides are not removed.
  • Page 26 RAZOR TIG 200 ACDC OPERATING MANUAL AC TIG Welding - AC Wave Balance Control Razor 32OAC/DC TIG-MMA In older machines, a balanced current output wave was achieved using a large number of capacitors in series or a battery in the welding circuit. Modern TIG power sources use electronics to create and maintain a balanced wave and now most AC TIG power sources produce a square wave current output.
  • Page 27 RAZOR TIG 200 ACDC OPERATING MANUAL TIG Welding Fusion Technique Manual TIG welding is often considered the most difficult of all the welding processes. Because the welder must maintain a short arc length, great care and skill are required to prevent contact between the electrode and the workpiece.
  • Page 28 RAZOR TIG 200 ACDC OPERATING MANUAL Tungsten Preparation Always use DIAMOND wheels when grinding and cutting, and be weary of breathing the dust created by the tugsten. While tungsten is a tough material, the surface of a diamond wheel is harder, and this makes for smooth grinding. Grinding without diamond wheels, such as aluminium oxide wheels, can lead to jagged edges, imperfections, or poor surface finishes not visible to the eye that will contribute to weld inconsistency and weld defects.
  • Page 29 RAZOR TIG 200 ACDC OPERATING MANUAL Tungsten Electrodes • Tungsten is a rare metallic element used for manufacturing TIG welding electrodes. The TIG process relies on tungsten’s hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410 degrees Celsius.

  • Page 34: Mma: Welding Guide

    RAZOR TIG 200 ACDC OPERATING MANUAL 12. MMA: Welding Guide One of the most common types of arc welding is Manual Metal Arc welding, also known as MMA welding. An electric current is used to strike an arc between the base material and a consumable electrode rod or ‘stick’. The electrode rod is made of a material that is compatible with the base material being welded.
  • Page 35 RAZOR TIG 200 ACDC OPERATING MANUAL Electrode Selection As a general rule, the selection of an electrode is straight forward, in that it is only a matter of selecting an electrode of similar composition to the parent metal. However, for some metals, there is a choice of several electrodes, each of which has particular properties to suit specific classes of work.

    RAZOR TIG 200 ACDC OPERATING MANUAL 14. TIG Troubleshooting 14.1 Tungsten burning away quickly • Incorrect gas or no gas: Use pure argon. Check cylinder has gas, connected, turned on, and torch valve is open. • Inadequate gas flow: Check the gas is connected, check hoses, gas valve and torch are not restricted.
  • Page 37 RAZOR TIG 200 ACDC OPERATING MANUAL 14.6 Arc wanders during welding • Poor gas flow: Check and set the gas flow between 8-12 L/min flow rate. • Amperage too low: Increase the amperage. • Incorrect arc length: Lower torch so that the tungsten is off of the work piece 2-5mm.
