3. use and maintenanCe
The amount of use and working environment should be taken into
consideration when planning the frequency of maintenance of MIG guns.
Careful use and preventive maintenance will help to ensure trouble-free
operation and long lifetime for the gun.
Due to high temperatures and wear, the welding end of MIG gun requires
most maintenance but also condition of other parts should be checked
regularly.
Welding end
• Remove welding spatter and check condition of insulations, contact tip and
gas nozzle. Replace damaged and worn-out parts. Use only original Kemppi
spare parts.
• Check condition of insulations. Replace damaged insulations immediately.
• Check that in the discharge holes for shielding gas there is no spatter or dirt.
• Use the gun in a proper way:
- Do not remove welding spatter by hammering the gun against the work
piece!
- Do not use sharp tools, because damaging of surfaces will increase
stickening of spatter!
- Do not bend neck body of gun or fasten the gun from neck body against
bench etc., for it may cause destruction of the neck!
- Do not use the gun as hammer!
gun cable
• Clean wire liner when replacing wire reel, or more often.
• Check daily that insulations of handle and gun cable are undamaged.
• Check that there are no sharp bends in gun cable.
