250/315 DC ARC Welders Identifying the Ground wire Caution: The machine may appear to operate with an incorrectly connected ground wire, but it will not operate properly. Selecting the correct ground wire is important for proper machine operation and personnel safety. Ground wires on LONGEVITY® Welding machines are usually one of the following colors: The ground wire is a dark green with a yellow stripe. The wire may also be just SOLID GREEN.

250/315 DC ARC Welders Main Unit Knob/Button/Function: 1. On/Off Breaker or Switch: Either breaker or switch located on the back or front of the unit will control the unit to be turned on or off. 2 Power Indicator: Shows unit is powered on. Indicator is present in some models with a green LED bulb. 3 Warning indicator: Illuminates when the duty cycle has been exceeded or the machine has overheated due to improper ventilation. Discontinue use until lamp goes out. Allow the fan to continue to run.
250/315 DC ARC Welders STICK/ARC Welding (Also known as MMA-Manual Metal Arc or Shielded Metal Arc Welding-SMAW) Connect the Stick torch to the - terminal and Torch Control receptacles. Connect the ground clamp to the + terminal and clamp the metal to be welded. Reverse the torch and ground connections for DCEP (Direct Current Electrode Positive). DC Stick - Select Stick, DC, desired amps using Base cur knob, Pulse Mode off. 1. Insert electrode into electrode holder.
250/315 DC ARC Welders horizontal, or overhead or a combination of two or more positions) and the flux type. Additional information may be given. Each manufacturer has their individual name and terminology as well. As there is no general recommendation that can be made about a particular electrode selection, except for practice welds, a electrode designated by the AWS as E 6011, E 6013, E 7014, or E 7018 may be used, each having its own distinct features and purpose.
250/315 DC ARC Welders electrode holder cable. Many electrodes run with in reverse polarity, (DCEP) setting. A few run with a straight polarity (DCEN). Some will run either way. For reverse polarity (DCEP) stick welding, swap the electrode holder and ground cable connections. Proper weld identification: Overlap and undercutting are two main causes of weld failure. Proper washing of the weld bead into the sides or “toes” of the weld is important.
250/315 DC ARC Welders Stick (SMAW) Electrode Welding Stick, the most basic of welding processes, offers the easiest option for joining steel and other metals. Although it produces the least pretties or cleanest welds, ARC/STICK welding gets the job done! Stick welding power sources deliver inexpensive options for welding versatility, portability and reliability.

250/315 DC ARC Welders Helpful Hints Use a drag technique for most applications. Take precautions with flying materials when chipping slag. Keep electrodes clean and dry - follow manufacturer instructions. Common steel electrodes (refer to chart above). Penetration: DCEN- Less penetration; AC Medium (can be more spatter also); DCEP - Most penetration Catalog and Capabilities LONGEVITY has what you need for stick welding, from welders to welding supplies and protective clothing.
250/315 DC ARC Welders Routine Maintenance The life of your machine and the quality of the work performed using your machine, will be enhanced by practicing periodic routine maintenance. At regular intervals, clear dust that may accumulate in the machine using clean and dry compressed air. If the working condition has heavy smoke and pollution, the welding machine should be cleaned once a month. Keep the machine exterior clean with mild soap and water.
