CORRECTION
While welding, keep the ignited end of the electrode further from the weld joint.
Adjust the current on the front of the Welder to a higher current setting.
While welding, keep the ignited end of the electrode closer to the weld joint.
Replace electrode with a new one.
While welding, keep the ignited end of the electrode closer to the weld joint,
Adjust the current on the front of the welder to a lower current setting.
Clean the weld joint of any dirt, grease, paint of other possible contaminates.
If the pieces being Welder are of a heavy gauge it may be necessary to bevel
the edges of the pieces.
Adjust the current on the front of the welder to a higher current setting.
Slow down the travel speed of the electrode while welding.
Allow the Welder to cool for a minimum of 15 minutes before attempting to use
again.
CORRECTION
Adjust voltage output to lower setting.
Adjust wire speed to slower setting.
Increase your travel speed with the Welding Gun.
Adjust voltage output to higher setting.
Adjust wire speed to faster setting.
Slow your travel speed of the Welding Gun making sure to pull or drag the molten
metal puddle.
Move the Contact Tip on the Welding Gun closer to the work piece to shorten the
length of exposed wire.
The MP200i is rated for a maximum thickness of 3/8", exceeding this will result
in poor penetration.
If welding heavy gauge metals, it may be necessary to increase the welding gap
between the two pieces and also bevel the edges on the weld side of the pieces.
Adjust voltage output to lower setting.
Adjust wire speed to slower setting.
Increase your travel speed with the Welding Gun.
Tack weld the pieces in multiple areas to keep the pieces from pulling apart.
Use welding clamps to secure the pieces in the proper shape.
To prevent warping, allow the workpiece to cool after welding small sections at
a time. Move your welding areas around by not completing all the welding in one
section all at once, rather, welding a small amount in one area and then move to
another section area to spread out the heat in the piece.
