OM-228 187 Page 33 9-2. 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. 3.5 x 125 A = 437 ipm 2 x 125 A = 250 ipm 1.
OM-228 187 Page 34 9-3. Holding And Positioning W elding 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 e nd of nozzl e, an d tip of wir e is p ositi oned corre ctly on sea m.
OM-228 187 Page 35 9-4. 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-228 187 Page 36 9-5. 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-228 187 Page 37 9-8. T roubleshooting − Excessive Spatter Excessive Spatter − scattering of molten metal particles that cool to solid form near weld bead. S-0636 Possible Causes Corrective Actions Wire feed speed too high. Select lower wire feed speed.
OM-228 187 Page 38 9-1 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-228 187 Page 39 9-14. T roubleshooting − W aviness Of Bead W aviness Of 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.
