Typical MIG Process Control Settings NOTE These settings are guidelines only. Material and wire type, joint design, fitup, position, shielding gas, etc.

Test welds to be sure they comply to specifications. Material thickness determines weld parameters. Convert Material Thickness to Amperage (A)9- 3.

Holding And Positioning Welding Gun NOTE Welding wire is energized when gun trigger is pressed. Before lowering helmet and pressing trigger, be sure wire is no more than 1/2 in (1.

Hold Gun and Control Gun Trigger Workpiece.. Conditions That Affect Weld Bead Shape NOTE 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.

Push Drag Perpendicular GUN ANGLES AND WELD BEAD PROFILES Short Normal Long.. Gun Movement During Welding NOTE Normally, a single stringer bead is satisfactory for most narrow groove weld joints; however, for wide groove weld joints or bridging across gaps, a weave bead or multiple stringer beads works better. Stringer Bead . Troubleshooting . S- 0. 63. 6 Possible Causes Corrective Actions Wire feed speed too high. Select lower wire feed speed. Voltage too high.

Select lower voltage range. Electrode extension (stickout) too long. Troubleshooting .

Lack of Penetration Good Penetration S- 0. Possible Causes Corrective Actions Improper joint preparation. Material too thick. Joint preparation and design must provide access to bottom of groove while maintaining proper welding wire extension and arc characteristics. Troubleshooting .

S- 0. 64. 1 Possible Causes Corrective Actions Welding wire extends too far out of nozzle. Be sure welding wire extends not more than 1/2 in (1. Unsteady hand. 9- 1.

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. Problem Probable Cause Remedy Welding arc not stable. Wire slipping in drive rolls. Adjust pressure setting on wire feed rolls.

Replace worn drive rolls if necessary. Wrong size gun liner or contact tip.

Match liner and contact tip to wire size and type. Incorrect voltage setting for selected wire feed speed on Readjust welding parameters. SECTION 1. 0 . Accessories PART NO. DESCRIPTION REMARKS 7.
