- [00:00:00.000]This is the oxyacetylene area.
- [00:00:02.160]First thing you want to do is
- [00:00:03.320]check your gas settings.
- [00:00:04.880]We have acetylene gas here. It's
- [00:00:06.680]going to be set at 10. The
- [00:00:08.390]oxygen is also going to be set
- [00:00:09.890]at 10.
- [00:00:10.660]Double check that. They should
- [00:00:12.130]be on, but double check, make
- [00:00:13.410]sure that's where they're at.
- [00:00:14.880]Then you'll be given a set of
- [00:00:16.570]tips to put onto your torch
- [00:00:18.180]body. They will have a number
- [00:00:20.020]on them.
- [00:00:20.660]This one is a 203. It could be
- [00:00:22.970]a 203, a 204, or a 205. Make
- [00:00:26.160]sure that's tight and ready to
- [00:00:28.040]light.
- [00:00:28.840]You'll have a striker. You'll
- [00:00:31.060]adjust your acetylene. Quarter
- [00:00:36.220]turn, strike it, adjust that
- [00:00:39.580]flame out
- [00:00:40.240]until it flares out about an
- [00:00:41.980]inch, and then adjust your
- [00:00:43.720]oxygen to get the neutral flame.
- [00:00:46.040]Weld your project, turn off the
- [00:00:49.020]gas, and turn off the oxygen.
- [00:00:52.080]Give your piece, your weldment,
- [00:00:56.720]to your emitter.
- [00:00:58.840]The instructor who's watching
- [00:01:00.050]the area, and they will mark
- [00:01:01.590]your number on it and put it in
- [00:01:03.080]the pile.
- [00:01:03.560]You wait for the next group.
- [00:01:04.720]Thank you.
