PROBLEM
CAUSE
CORRECTION
Burn Through
High Voltage
Adjust voltage output to lower setting.
Fast Wire Speed
Adjust wire speed to slower setting.
Slow Gun Travel
Increase travel speed with the welding gun.
Lack of
Penetration
Low Voltage
Adjust voltage to higher setting.
Slow Wire Speed
Adjust wire speed to faster setting.
Fast Gun Travel
Slow your travel speed of the welding gun making sure to pull or drag the
molten metal puddle.
Excessive Wire Stick Out
Move the contact tip on the welding gun closer to the work piece to shorten the
length of exposed welding wire.
Material Too Thick
The MIG135 is rated for a maximum thickness of 1/4", exceeding this will result
in poor penetration.
Poor Material Prep
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.
Excessive
Penetration
High Voltage
Adjust voltage to lower setting.
Fast Wire Speed
Adjust wire speed to slower setting.
Slow Gun Travel
Increase travel speed with the welding gun.
Warping
Lack of Tack Welds
Tack weld the pieces in multiple areas to keep the pieces from pulling apart.
No Clamping
Using welding clamps to secure the pieces in their proper shape.
Poor Technique
To prevent warping, allow the piece 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 than welding a small amount in one area and then
move to another to spread out the heat in the piece.
Poor Fusion
Low Voltage
Adjust voltage output to a higher setting.
Slow Wire Speed
Adjust wire speed to a higher setting.
Dirty Base Metal
Remove all paint, rust, oil, grease, dirt, or any other contaminants that may be
on the surface of the piece.
Excessive Wire Stick Out
Move the contact tip on the welding gun closer to the work piece to shorten the
length of exposed welding wire.
Cold Base Metal
If welding a large piece, particularly cast pieces, which may absorb a lot of
heat, it may ne necessary to pre heat your part with a torch.
