Model G0879 (Mfd. Since 6/19)
Difficulty/
inability to
properly start/
arc a weld.
1. Improperly cleaned workpiece/ wrong type of
material.
2. Ground clamp not connected to workpiece/
too far from weld location/bad ground
connection.
3. Machine settings incorrect for workpiece.
4. Residue build up at end of wire insulates
electrode and makes starting arc difficult.
1. Clean workpiece/ use correct type of material.
2. Connect ground clamp close to workpiece. Make
sure ground clamp is connected/terminals are clean
(
Page 13).
3. Adjust machine settings to be appropriate for
workpiece (
Page 25).
4. Break/cut tip of wire off before beginning weld.
Burning holes
in workpiece.
1. Material too thin for welding operation.
2. Welding amperage output too high.
3. Wire speed too high.
4. Welding torch moved too slow.
5. Contact tip to workpiece distance to long.
1. Use thicker material. Not recommended to weld
material thinner than
1
⁄
16
" steel with G0879 (
Page 7).
2. Lower amperage output.
3. Reduce wire speed.
4. Increase welding torch travel speed.
5. Maintain contact tip to workpiece distance of
3
⁄
16
"-
1
⁄
4
"
(
Page 24).
Lack of weld
penetration.
1. Improperly cleaned workpiece/ wrong type
of material/ material too thick for welding
operation.
2. Welding output amperage too low.
3. Wire speed too slow.
4. Welding torch moved too quick.
5. Contact tip to workpiece distance to short.
1. Clean workpiece/ use correct type of material/
maximum material thickness for G0879 is
3
⁄
16
" steel
(
Page 7).
2. Increase amperage output.
3. Increase wire speed.
4. Decrease welding torch travel speed.
5. Maintain contact tip to workpiece distance of
3
⁄
16
"-
1
⁄
4
"
(
Page 24).
Unable to
maintain
constant arc;
excessive
spatter.
1. Contact tip to workpiece distance too long.
2. Ground clamp not connected to workpiece/
too far from weld location/bad ground
connection.
3. Welding output amperage too high.
4. Wire speed too high.
5. Welding torch moved too slow.
1. Maintain appropriate contact tip to workpiece distance
throughout entire weld.
2. Connect ground clamp close to workpiece. Make
sure ground clamp is connected/terminals are clean
(
Page 13).
3. Lower amperage output.
4. Reduce wire speed.
5. Increase welding torch travel speed.
