WELDMAX 185i Selecting the Right Tungsten Electrodes: Selecting the right tungsten is crucial to a successful TIG weld. You have to insure the correct tungsten is used for the type of metal you are welding, the type of technology used in your welder such as transformer or inverter, and the thickness of the metal you will need to weld.

WELDMAX 185i Selecting the right FILLER RODS FOR TIG WELDING: Filler Rods are essential to TIG Welding because the filler rod is fed into the molten puddle by hand filling in the puddle to create a stronger metal bond or puddle to join two metal pieces. It is extremely important to have the right filler rod based on the metal you are welding. It is also necessary to have the right tungsten to insure you are properly setup to weld your metal.
WELDMAX 185i 6. 1/16” diameter filler should be used when material is 1/8” and less thick. 3/32” diameter filler rod can be used for 1/8” and thicker material. For more info on Filler Rods, go to www.freeweldingforum.com Setting Up the Argon Regulator: The argon regulator (pictured below) is included with your unit. Setting it up to your argon bottle is easy. Simply screw in the valve to the bottle and set the pressure to about. Use 100% Argon at 15-25 CFH (cubic feet per hour).
WELDMAX 185i Basic TIG Operation (Tungsten Inert Gas - Gas Tungsten Arc Welding - GTAW) TIG Operation and Principles: Shielding Gas: Use 100% Argon at 15-25 (cubic feet per hour). Set the gas flow using the regulator on the gas bottle. Use higher flow when extending the tungsten electrode to reach into corners or gaps. Tungsten Electrode: We recommend 2% Thoriated tungsten (red) for TIG welding with our DC TIG welders.
WELDMAX 185i complete a weld. In certain applications, TIG welding can be performed without the use of a filler rod. One of the biggest issues for beginning welders is holding and maintaining an arc. Starting an arc with your High Frequency welder is quite simple. Set the machine for TIG operation then select the desired amperage. Grasp the torch in a manner that is comfortable to you. Place the torch so that the tungsten is no more than 1/8 inch from the weld surface.
WELDMAX 185i Length of Arc When an arc is too long, the metal melts off the electrode in large globules and the arc may break frequently. This produces a wide, spattered, and irregular deposit with insufficient fusion between the base metal and the weld. When an arc is too short, it fails to generate enough heat to melt the base metal properly, causes the electrode Fig. 3 Setting the length of an arc to stick frequently to the base metal, and produces uneven deposits with irregular ripples.

WELDMAX 185i STICK/ARC Welding Stick Welding (Also known as MMA-Manual Metal Arc or Shielded Metal Arc WeldingSMAW) 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 1. Insert electrode into electrode holder.
WELDMAX 185i system of letters and numbers determined by the American Welding Society (AWS). The rating system includes the minimum tensile strength of the finished weld, the weld position (flat, vertical, 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.
WELDMAX 185i 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. Keep the welding electrode or the TIG tungsten and welding arc within the weld joint to prevent overlap. Pausing on the sides of the welds to wait for the sides to fill reduces the chance of undercutting, even if the current is a little too high.

WELDMAX 185i Helpful Hints Use a drag technique for most applications. Take precautions with flying materials when chipping slag. Keep electrodes clean and dry - follow manufacturers 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.
WELDMAX 185i 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. Do not walk on or store items on the cables or cords.
