CORRECTION
Make sure that Electrodes are clean and dry before use.
Clean base metal of any oil, debris, coatings, or moisture. If base
metal is cold rolled steel make sure to remove any mill scale.
The angle of the electrode should be at 45° and drug away from the
weld arc. Failing to do so may cause poor weld appearance.
Reduce heat & allow more time between passes.
Preheat base metal (consult welding codes for requirements)
Use correct filler wire type & diameter for the joint being welded.
Clamp work piece tightly & weld while clamps are in place.
Add more tack welds until rigidity and stiffness is developed.
To reduce heat it is best to spread the welding out around the area.
This can be done by using stitch welding techniques, alternating
sides, and/or taking your time and allowing the pieces to cool
between passes.
Make sure that Electrodes are clean and dry before use.
Clean base metal making sure to remove any oil, debris, coatings,
or moisture.
Check Ground connection. Make sure that the ground is on a freshly
cleaned surface and close to the welding area. It is suggested to
weld toward the ground connection
Based on the material welding & size/material of the electrode,
pick an appropriate amperage to perform the desired weld.
Clean base metal of any oil, debris, coatings, or moisture. If base
metal is cold rolled steel make sure to remove any mill scale.
Move electrode so that it is contacting the weld puddle and feed rod
into the puddle as needed.
