How To Guide

An oxy-acetylene torch burns near 6,000F and feeds its own oxygen, so setup errors turn into fires and flashbacks fast. This guide covers cylinder handling, the 15 psi acetylene rule, flashback arrestors, soapy-water leak tests, shade 5 eye protection, and the OSHA 35-foot fire watch rule, plus a start-to-finish cutting walkthrough.

A first MIG weld goes wrong in predictable ways: arc flash from lifting the hood too early, sunburn through a T-shirt, fume breathed at the plume, and a spark smoldering in a rag pile. This guide sets up welding PPE from the head down, decodes what each piece must be rated for, and covers the 35-foot fire rule beginners never learn.
