WELDING GUIDELINES
General
The DW2130 can utilize the Flux Cored Arc Welding (FCAW) process.
Arc Welding Basics
Six basic techniques affect weld quality. These are: wire selection, heat setting, weld angle, wire speed,
travel speed, and electrode extension. An understanding of these techniques is necessary for effective
welds.
HEAT SETTING
The correct heat involves the adjustment of the welding machine to the required setting. Heat or voltage is
regulated by a switch on the welder. The heat setting used depends on the size (diameter) and type of wire,
position of the weld, and the thickness of the work piece. Consult specifications listed on the welder. It is
suggested that the welder practice with scrap metal to adjust settings, and compare welds with Figure 4.
WIRE TYPE AND SIZE
The correct choice of wire type involves a variety of factors, such as welding position, work piece material
type, thickness, and condition of surface to be welded. The American Welding Society, AWS, has set up
certain requirements for each type of wire.
