*Welding generator* = a machine that gives you 2 things in 1 box:
1. *Welding power* - DC or AC/DC current to run stick, TIG, MIG
2. *Generator power* - 120V/240V electricity to run tools, lights, grinders
Basically a gas or diesel engine + welder + generator all built together. Super popular for field work.
*How it works*
Gasoline or diesel engine spins an alternator. That makes:
- *Welding output*: High-current DC, usually 200A - 500A
- *Aux power*: 5kW - 15kW of 120V/240V AC for tools
*Key specs to check*
**Spec** **What it means**
**Welding Amps** 200A = light fab. 300A = most jobs. 500A = heavy plate, gouging
**Duty Cycle** % of 10min you can weld at max amps. 100% @ 250A is pro grade
**Aux Power** 8kW - 12kW is common. Runs grinders + lights while you weld
**Fuel** Gasoline = cheaper, quieter. Diesel =
