Operating the Hobart Beta MIG II
Once the machine is set up, it's time to start welding. Here’s how to operate the Hobart Beta MIG II effectively:
1. Adjusting Settings
- Set the voltage and wire feed speed according to the material thickness and type.
- Refer to the welding chart provided in the manual for guidance on recommended settings.
2. Welding Technique
- Hold the welding gun at a 15-20 degree angle relative to the workpiece.
- Maintain a consistent distance of approximately 1/4 inch between the nozzle and the workpiece.
- Move the gun in a steady motion, either in a straight line or in a weaving motion, to ensure an even bead.
3. Monitoring the Weld Pool
- Keep an eye on the weld pool to ensure it is melting properly without excessive spatter.
- Adjust the speed and angle of the gun as necessary to maintain control over the weld.
4. Finishing the Weld
- Once the weld is complete, lift the welding gun and allow the weld to cool.
- Inspect the weld for consistency, penetration, and overall quality.
