PROMTS 252i MIG Operation: 1. Shielding Gas Choice 1)When the wire material is Fe, the shielding gas should be 75% Ar + 25% CO2 2)When the wire material is Ss, the shielding gas should be 75% Ar + 25% CO2 3)When the wire material is Al, the shielding gas should be 100% Ar MIG Welding Tips and Tricks MIG Welding Tips 1. Direct your wire at the leading edge of your weld pool for the most control of your weld bead. 2.
PROMTS 252i Never let you electrode’s distance from you contact tube exceed ¼” to ¾”. If you do your weld will not be correct. Too Short Normal Too Long Welding Wire Thin Metal= Thin Diameter. Thick Metal= Larger wire, with a larger machine. Us the wire that matches your metal.

PROMTS 252i WELDING WIRES Shielding gas- C02 or 75%Argon/25% Solid Carbon-Steel ER70S-6 CO2 is recommended and will give you deeper penetration 75%Argon/25% will give you less splatter and a nicer lookingbead Should be used indoors, where wind cannot harm you weld. Allows you to weld materials thinner than what you would weld with flux cored wires Great for auto body work .
PROMTS 252i Aluminum should be used with Argon.

PROMTS 252i Fillet Welds The leg of your weld should be equal to the thickness of the materials you welded. Aluminum MIG Welding Tips • It is highly recommended to use a spool gun when welding with aluminum. However, if you don’t have access to one, you can try using an extremely short gun. • Keep your gun straight.
PROMTS 252i • Fill the crater at the end of the weld to avoid a crack. One way to do this is to dwell in the weld pool for a second at the end of the weld. STICK Welding Tips and Tricks (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).
PROMTS 252i flux and bare metal meet. A welding rod must have flux to shield the weld from the atmosphere or the weld will fail. 4. Use the Current control to change arc qualities. Adjust the amperage according to the recommendations of the electrode (welding rod) manufacturer for the type and size of the electrode used. Experimentation will be required to find the optimal setting desired. It is an excellent tool for out of position welding. 5. Electrode selection.

PROMTS 252i 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.

PROMTS 252i 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.
