LN-25 Wire Feeder
Portable, Construction Wire Feeder
The LN-25 semiautomatic wire feeder is ideal for field or construction use. Since it is
powered across the arc, no control cables are needed! Simply connect the weld cable,
attach the arc sensing clip, and you’re ready to go. This portable MIG and flux-cored wire
feeder comes in a fully enclosed case to protect against damage on the job site. The
LN-25 features a tool-less quick release mechanism for easy wire changing, and it
accepts 10-44 lbs. (4.5-19.9 kg) wire packages for plenty of welding versatility.
