Ideal for the beginner welder, this machine welds 24 ga to 3/16 in steel.


A breakthrough control that automatically sets your welder to the proper parameters. In the Millermatic 125 Hobby it's available for .030 solid wire with 75/25 shielding gas. Simply set the wire diameter, set the material thickness, and start welding!
All Aluminum Drive System
Robust wire drive with Quick Select™ drive roll and calibrated tension knob creates consistent feeding and easy setup.
115V Input Power
Uses 115V household input power so there are no special power requirements.
Manual Mode
Gives you the flexibility to manually set the machine when welding stainless steel or anytime you want to set your own parameters on mild steel.
Quick Select™ Drive Roll
Makes setup quicker by offering three grooves - two for different size solid wire and a third for flux-cored wire.
Thermal Overload
Shuts down the unit and activates the over-temperature light if the airflow is blocked or duty cycle is exceeded.
