RAZOR ARC 160/200 PFC OPERATING MANUAL 9. 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.

RAZOR ARC 160/200 PFC OPERATING MANUAL 9.1 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 ARC 160/200 PFC OPERATING MANUAL 11. TIG: Welding Guide 11.1 DC TIG Welding The DC power source uses what is known as DC (direct current), in which the main electrical component known as electrons flow in only one direction from the negative pole (terminal) to the positive pole (terminal). In the DC electrical circuit, there is an electrical principle at work which should always be taken into account when using any DC circuit.

RAZOR ARC 160/200 PFC OPERATING MANUAL 11.3 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. Similar to Oxygen Acetylene torch welding, TIG welding typically requires two hands and in most instances requires the welder to manually feed a filler wire into the weld pool with one hand while manipulating the welding torch in the other.

RAZOR ARC 160/200 PFC OPERATING MANUAL 11.7 Tungsten Preparation Always use DIAMOND wheels when grinding and cutting. 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.
The No-Load voltage is too high. This is likely caused by VRD fault. Possible Solution: Power down and restart machine. After attempting the possible solutions listed in the chart above please contact UNIMIG Support Services if you are still experiencing issues with your machine.
