Feeding

problems

Many feeding problems are caused

by improper handling of the gun

cable or wire.

• Do not kink or pull the cable
  around sharp corners. Keep the
  gun cable as straight as possible
  when welding.


• Do not allow people to stand
  on or run over the MIG gun
  or leads.


• Innershield wire has proper
  surface lubrication on it. Hard
  wire does not, so use only clean,
  rust-free wire.


• Replace the nozzle contact tip
  when it becomes worn or the
  end appears fused or deformed.


• Your MIG torch is the delivery
  device for your gas and wire.
  Look after it.


• Replace your torch tip regularly.
  They do not last forever.
