In an embodiment, the claimed invention includes an oral-fluid collection and testing device that. is simple to operate. The device includes a body assembly and a cap assembly that are easy to handle by a user. A collection sponge projects from an end of the body assembly for absorbing the oral fluid of a donor, A cap assembly is easily aligned with the body assembly by way of visual alignment indicators on both the body and the cap. Once the cap is aligned with the body, a user simply pushes the cap onto the 'body, which causes a first stage fluid, flow. More specifically, a buffer fluid is released from the cap and mixes with the oral fluid collected on the sponge—After waiting a short time* the cap is rotated, then pushed again, causing a second-stage fluid flow in which the sponge is compressed such that the buffer fluid/oral fluid exits the sponge and flows toward a. pair of test strips. A user can then easily view the test results by observing a visual indication, such as a color change of the test strips through a viewing window.

If a short circuit does not occur during deceleration of a wire feed speed in forward feed of a welding wire before the wire feed speed reaches a predetermined wire feed speed, a cyclic change is stopped and the wire feed speed is constantly controlled at the first feed speed. If a short circuit occurs during forward feed at the first feed speed, deceleration from the first feed speed starts, and the cyclic change is resumed for welding. This achieves uniform weld bead without increasing spatters even if any external disturbance such as change of distance between a tip and base material occurs.
