To correct that shortcoming, a three-component team with members from HQ AFRC, the Air National Guard Readiness Center and the ARC Requirements Cell built and fielded an online geospatial tool called ARC Force Visibility that provides authorized active and reserve component leaders and their staffs an online interactive and secure view of the current location of ARC forces.
During the CMT welding, under the action of arc pressure, metal impact and surface tension, the surface of pool becomes concave-convex: in the front of pool, due to the continuous impact of metal and the action of arc force, the surface of pool becomes obviously concave; and at the back of pool, with the increase of filling metal and the concave deformation of front pool, the rear pool becomes convex to produce a reinforcement.
In addition to adjustable Stick Arc Force and Hot Start control, both units feature dedicated modes to optimise performance for specific processes, including 6010 electrodes, 7018 electrodes and air carbon-arc gouging with carbons up to 3/16".
T h e machine's fixed arc force allows the operator to get deeper penetration into the plate without the electrode sticking.
True MMA welding characteristics are provided in both AC and DC modes including hot start, arc force and polarity switch (DC).
Other features include easy starts and re-starts Stick mode, adjustable arc force, Touch Lift TIG Start capability, and an Auto Fan feature that turns the fan motor on and off as needed for energy savings.
This machine can also be used for MMA welding and is rated 160A and features adjustable Hot Start, adjustable Arc Force for improved penetration and to avoid electrode sticking as well as an AVC (Antidust Ventilation Corridor) air cooling system that draws clean air through the back of the machine, thereby reducing dust and dirt contamination of the machine's electronic components.
The Caddy[TM] Arc 151i and 201i single-phase DC/CC power supplies are designed primarily for SMAW (Stick) and feature an adjustable arc force that sets the intensity of the arc to ensure weld quality.
Other features include easy starts and re-starts stick mode, adjustable arc force, Touch Lift TIG Start capability, and an Auto Fan feature that automatically turns the fan motor on and off as needed for energy savings.
Fortunately, increasing the frequency ("constricting the nozzle") narrows the shape of the arc cone and increases arc force. This stabilizes the arc, reduces arc wandering and provides excellent directional control over the arc and weld puddle (which is why many operators say it reminds them of welding steel with a DC arc).
