OM-230 693 Page 36 SECTION 8 − MIG WELDING (GMA W) GUIDELINES 8-1. T ypical MIG Process Connections ! W eld current can damage electronic parts in vehicles. Disconnect both battery cables before welding on a vehicle. Pl a c e w o r k c l a m p a s close t o the weld as possible.
OM-230 693 Page 37 8-2. T ypical MIG Process Control Settings . These settings are guidelines only . Material and wire type, joint design, fitup, position, shielding gas, etc. affect settings. T est welds to be sure they comply to specifications. 1/8 or .
OM-230 693 Page 38 8-3. Holding And Positioning Welding Gun . W elding wire is energized when gun trigger is pressed. Before lowering helmet and pressing trigger , be sure wire is no more than 1/2 in (13 mm) past end of nozzle, and tip of wire is positioned correctly on seam.
OM-230 693 Page 39 8-4. Conditions That Affect Weld Bead Shape . Weld bead shape depends on gun angle, direction of travel, electrode extension (stickout), travel speed, thickness of base metal, wire feed speed (weld current), and voltage.
OM-230 693 Page 40 8-5. Gun Movement During Welding . Normally , a single stringer bead is satisfactory for most narrow groove weld joints; however , for wide groove weld joints or bridging acros s gaps, a weave bead or multiple stringer beads works better .
OM-230 693 Page 41 8-8. T roubleshooting − Excessive Spatter Excessive Spa tter − scattering of molten metal partic les that cool t o solid form near weld bead. S-0636 Possible Causes Corrective Actions Wire feed speed too high. Select lower wire feed speed.
OM-230 693 Page 42 8-1 1. T roubleshooting − Lack Of Penetration Lack Of Penetration − shallow fusion between weld metal and base metal. Lack of Penetration Good Penetration S-0638 Possible Causes Corrective Actions Improper joint preparation. Material too thick.
OM-230 693 Page 43 8-14. T roubleshooting − W aviness Of Bead W aviness O f Bead − weld metal that is not parallel and does not cover joint formed by base metal. S-0641 Possible Causes Corrective Actions W elding wire extends too far out of nozzle.
OM-230 693 Page 44 8-16. Common MIG Shielding Gases This is a general chart for common gases and where they are used. Many different combinations (mixtures) of shielding gases have been developed over the years. The most commonly used shielding gases are listed in the following table.
OM-230 693 Page 45 Problem Remedy Probable Cause W elding arc not stable. Wire slipping in drive rolls. Adjust pressure setting on wire feed rolls. Replace worn drive rolls if necessary . W rong size gun liner or contact tip. Match liner and contact tip to wire size and type.
OM-230 693 Page 46 SECTION 9 − P ARTS LIST 9-1. Drive Roll And Wire Guide Kits . Base selection of drive rolls upon the following recommended usages: 1 V -Grooved rolls for hard wire. 2 U-Grooved rolls for soft and soft shelled cored wires. 3 U-Cogged rolls for extremely soft shelled wires (usually hard surfacing types).
