VIPER MIG 165 OPERATING MANUAL 6.3 Inductance Adjustment Knob Inductance is what allows you to change the frequency of your short circuit – how often the wire touches the joint in the circuit’s cycle. The lower your inductance setting, the more frequently your weld will short circuit. Less metal is being added, so the bead is narrower and freezes faster.

VIPER MIG 165 OPERATING MANUAL 11. MIG: Welding Guide 11.1 MIG (Metal Inert Gas) Welding MIG (Metal Inert Gas) welding, also known as GMAW (Gas Metal Arc Welding) or MAG (Metal Active Gas Welding), is a semi-automatic arc welding process in which a consumable wire electrode and a shielding gas are fed through a welding gun.
Page 25
VIPER MIG 165 OPERATING MANUAL MIG: Welding Guide 11.3 Basic MIG Welding Good weld quality and weld profile depend on gun angle, the direction of travel, electrode extension (stick out), travel speed, the thickness of base metal, wire feed speed (amperage) and arc voltage. To follow are some basic guides to assist with your setup.
Page 26
VIPER MIG 165 OPERATING MANUAL MIG: Welding Guide 11.4 Travel Angle The travel angle is the right to left, relative to the direction of welding. A travel angle of 5°- 15° is ideal and produces the right level of control over the weld pool. A travel angle higher than 20° will give an unstable arc condition with poor weld metal transfer, less penetration, high levels of spatter, weak gas shielding and a poor quality finished weld.
Page 27
VIPER MIG 165 OPERATING MANUAL MIG: Welding Guide 11.7 Travel Speed Travel speed is the rate that the gun is moved along the weld joint and is usually measured in mm per minute. Travel speeds can vary depending on conditions and the welder's skill and is limited to the welder's ability to control the weld pool.

VIPER MIG 165 OPERATING MANUAL MIG: Welding Guide 11.8 Wire Types and Sizes Use the correct wire type for the base metal being welded. Use stainless steel wire for stainless steel, aluminium wires for aluminium and steel wires for steel. Using poor quality milled wire can result in poor performance and appearance. To ensure optimal performance when welding, use standards approved wire.

VIPER MIG 165 OPERATING MANUAL 16. 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.

VIPER MIG 165 OPERATING MANUAL 18. TIG: Welding Guide 18.1 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.
Page 46
VIPER MIG 165 OPERATING MANUAL TIG: Welding Guide 18.3 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.

VIPER MIG 165 OPERATING MANUAL TIG: Welding Guide 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 49
VIPER MIG 165 OPERATING MANUAL TIG: Welding Guide 18.7 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.
VIPER MIG 165 OPERATING MANUAL 19. Drive Roller Selection The importance of smooth, consistent wire feeding during MIG welding cannot be emphasised enough. The smoother the wire feed, the better the welding will be. Feed rollers or drive rollers are used to feed the wire mechanically along the length of the welding gun.
VIPER MIG 165 OPERATING MANUAL 20. MIG Troubleshooting 20.1 Excessive Spatter • Wire feed speed set too high: Select lower wire feed speed. • Voltage too high: Select a lower voltage setting. • Wrong polarity set: Select the correct polarity for the wire being used - see machine setup guide.
