E1/16" X 36" ER80SD-2 Steel Wire Longevity offers quality filler rods at affordable prices. Please take a look at the selection of filler rods that we carry to decide what the best application of rod will be for your weld. -
Page 15: Argon Regulator Installation
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. -
Page 16: Basic Tig Operation
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. - Page 17 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.
- Page 18 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.

Page 20: Basic Stick/Arc Welding Operation
WELDMAX 185i STICK/ARC Welding Stick 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). - Page 21 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.
- Page 22 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.
