I just started my welding program and all we have done so far is oxyacetylene cutting. My teacher said that my 100% cotton work shirt is suitable for the job but my question is will I need a heavier duty jacket for mote advanced welding or complicated position in the future? I like to be prepared and even if I'm not going to need a FR jacket until my second year I'd still like to have one now so I don't have to stress over it later. The other thing is I don't want flame retardant because my mother doesn't want me getting cancer from it. Cow heid or any other leather seems expensive but I did see a split cow leather and cotton heavy duty jacket on sale that I have my eye on if the purchase is necessary. So what do y'all think? Will I need to buy a stronger jacket or does my mediocre work shirt fit the job? I plan on doing welding for the rest of my career and will be doing OAW, GMAW, GTAW, and basically every other common kind.
