OPERATING MANUAL
6. Arc wanders during welding
•
Poor gas flow:
Check and set the gas flow between 8-12 L/min flow rate.
•
Amperage too low:
Increase the amperage.
•
Incorrect arc length:
Lower torch so that the tungsten is off of the work piece 2-5mm.
•
Tungsten incorrect or in poor condition:
Check that correct type of tungsten is being used. Remove 10mm from the
weld end of the tungsten and re-sharpen the tungsten.
•
Poorly prepared tungsten:
Grind marks should run lengthwise with tungsten, not circular. Use proper grinding method
and wheel.
•
Contaminated base metal or filler wire:
Remove contaminating materials like paint, grease, oil, and dirt, including mill
scale, from base metal. Remove all grease, oil, or moisture from filler metal.
7. Arc difficult to start or will not start welding
•
Incorrect machine set up:
Check machine set up is correct.
•
No gas, incorrect gas flow:
Check the gas is connected and cylinder valve open, check hoses, gas valve and torch are
not restricted. Set the gas flow between 8-12 L/min flow rate.
•
Incorrect tungsten size or type:
Check and change the size and or the tungsten if required.
•
Loose connection:
Check all connectors and tighten.
•
Earth clamp not connected to work:
Connect the earth clamp directly to the workpiece wherever possible.
19. MMA (STICK) Troubleshooting
1. No arc
•
Incomplete welding circuit:
Check earth lead is connected. Check all cable connections.
•
Wrong mode selected:
Check the MMA selector switch is selected.
•
No power supply:
Check that the machine is switched on and has a power supply.
2.
Porosity - Small cavities or holes resulting from gas pockets in weld metal
•
Arc length too long:
Shorten the arc length.
•
Workpiece dirty, contaminated or moisture:
Remove moisture and materials like paint, grease, oil, and dirt, including
mill scale, from base metal.
•
Damp electrodes:
Use only dry electrodes.
3. Excessive spatter
•
Amperage too high:
Decrease the amperage or choose a smaller electrode.
•
Arc length too long:
Shorten the arc length.
4. Weld sits on top, lack of fusion
•
Insufficient heat input:
Increase the amperage or choose a smaller electrode.
•
Workpiece dirty, contaminated or moisture:
Remove moisture and materials like paint, grease, oil, and dirt, including
mill scale, from base metal.
•
Poor welding technique:
Use the correct welding technique or seek assistance for the correct technique.
