Summary

Home of metal fragments and welding fumes, the metal shop is home to many tools capable of shaping, cutting, and fusing metal.

Metal Shop User Guide

1. Gas Cylinders:
   1. Tank Exchange Area: This is a corner outside the auto bay and classroom where new and empty tanks are kept. If a tank is empty, please mark it as such with a tag and move it to the tank exchange area.
2. Welder Set-up: We have our MIG wire welders set up for steel welding. If you intend to use a machine for something other than steel, please carefully set up your machine, and change everything back for steel when you are done. The gas hooked up to the machine should be Argon/CO2 75/25 mix, the wire should be mild steel wire (typically .030), and tip should match the wire diameter, and the drive wheel for the wire should be on in the correct position for the wire diameter.
3. Welding Curtain: Make sure the curtain to the wood shop is closed when you are welding, torching, brazing, plasma cutting, or any process that emits harmful light.
