If your LOKERMANN Welding System has no arc, first ensure the earth lead is properly connected and all cable connections are secure. Then, verify the machine is switched on and has a stable power supply. Finally, check that the MMA selector switch is correctly selected.
What to do if LOKERMANN GRAND MIG 351 MULTI SYN Welding System has excessive spatter?
If your LOKERMANN Welding System is producing excessive spatter, it might be due to the amperage being too high. Try decreasing the amperage or using a larger electrode. Another potential cause is an arc length that is too long; in that case, shorten the arc length.
Why does LOKERMANN Welding System have porosity in the weld?
If you observe porosity (small cavities or holes) in the weld metal when using your LOKERMANN Welding System, it could be due to several reasons. First, the arc length may be too long, so try shortening it. Second, the workpiece might be dirty, contaminated, or contain moisture; remove any moisture and materials like paint, grease, oil, dirt, and mill scale from the base metal. Finally, damp electrodes can cause porosity, so ensure you are using only dry electrodes.
Why does LOKERMANN GRAND MIG 351 MULTI SYN have lack of penetration?
If your LOKERMANN Welding System weld shows a lack of penetration, it may be due to insufficient heat input. Increase the amperage or choose a larger electrode. It could also be caused by poor welding technique, so use the correct welding technique or seek assistance. Poor joint preparation may also be the culprit; check the joint design and fit up, ensuring the material is not too thick, and seek assistance for the correct joint design and fit up if needed.
Why does weld sit on top when using LOKERMANN GRAND MIG 351 MULTI SYN Welding System?
If the weld sits on top without proper fusion when using your LOKERMANN Welding System, it could be due to insufficient heat input. Try increasing the amperage or choosing a larger electrode. Also, ensure the workpiece is clean by removing moisture, paint, grease, oil, dirt, and mill scale. Finally, poor welding technique can also lead to this issue, so use the correct welding technique or seek assistance.
How to prevent burn through with LOKERMANN Welding System?
If your LOKERMANN Welding System is causing excessive penetration or burn-through, it is likely due to excessive heat input. Reduce the amperage or use a smaller electrode. Another possible cause is incorrect travel speed; try increasing the weld travel speed.
What causes distortion when welding with LOKERMANN GRAND MIG 351 MULTI SYN Welding System?
If you notice distortion (movement of base metal) during welding with your LOKERMANN Welding System, it could be due to excessive heat input. Reduce the amperage or use a smaller electrode. Poor welding technique can also cause distortion, so use the correct welding technique or seek assistance. Lastly, poor joint preparation and/or joint design may be the issue; check the joint design and fit up, ensure the material is not too thick, and seek assistance if needed.
How to fix uneven weld appearance with LOKERMANN Welding System?
If your LOKERMANN Welding System is producing an uneven weld appearance, it may be due to an unsteady or wavering hand. To stabilize, use two hands where possible and practice your technique.
