FAQs

Q: Can I use a spool gun for steel wires?

A: No – spool guns are optimized for aluminum wires. For steel, use a standard MIG gun.

Q: How do I prevent wire feed issues?

A: Regularly clean the liner and use U-groove rollers for consistent tension.

Q: Is a gasless MIG spool gun available?

A: Spool guns require shielding gas (argon/CO2 mix) for aluminum welding.
