Handle - Rugged, top mounted handle allows for easy transport of your welder.

Wire Speed Control - Use this dial to adjust the speed at which the welder feeds wire to the gun. 1 is the slowest wire feed speed, 10 is the highest. You will need to adjust or "tune-in" your wire speed for different welding conditions (thickness of metals, gas -vs- gasless welding, metal type, wire size, etc.). When the wire speed is properly "tuned-in" the welding wire will melt into the material you are welding as quickly as it is fed through the welding gun.

Voltage Selector- This four position dial adjusts the voltage or "heat" of your welder. A is the lowest and D is the highest. Different materials and material thickness will require different voltage settings. You will need to adjust your voltage accordingly for different welding conditions. By properly adjusting your voltage settings and wire feed speed, you will enable clean, precision welds. (Refer

to the Suggested Settings Chart on p.30 of this manual OR on the inside of the door of

the welder.)

Power Switch - This switch turns the welder ON and OFF. (Make sure the power switch is in the OFF position before performing any maintenance on the welder.)

Power Cord - This is a standard, grounded 120 volt power cord. (Make sure you are

using a properly grounded 120 Vac, 60Hz, single phase, 20 amp power source.)

Ground Clamp -Attaching the ground clamp to your work piece "completes" the welding current circuit. You must attach the ground clami_ to-the metal you are welding. If the ground clamp is not connected to the metal work piece you intend to weld, the welder will not have a completed circuit and you will be unable to weld. A poor connection at the ground clamp will waste power and heat. Scrape away dirt, rust, scale, oil or paint before attaching the ground clamp.

Ground Cable - The ground cable connects

the ground clamp to the internal workings of the welder.

Welding Gun and Cable - The welding gun controls the delivery of the welding wire to the material to be welded. The welding wire is fed through the welding cable and welding gun when the welding gun trigger is pulled. You will need to install a contact tip and welding nozzle to the end of the welding gun, as described later in this manual, prior to welding.

Welding Terms

Now that you are familiar with the main parts of the welder, make note of the following

terms. You will see them used throughout this manual.

weld puddle: The localized volume of molten metal in a weld prior to its solidification.

weld angle: The angle of the welding wire, as it extends from the welding gun, in relation to the item being welded.

slag: The protective coating that forms on the surface of molten metal.

arc: A sustained luminous discharge of electricity across a gap in a circuit. welding bead: The extended build up of a weld, made by pushing or pulling the weld puddle.
