long torch question

admin

Question, can you run a 2-4' long torch with 50' leads on the powermax 45xp? the reason I ask is I don't really need a bigger unit at the moment than the 45 xp. As of now I run the 30xp and that is plenty big. but it would be nice to have a long torch for some stairs I'm working on replacing. Right now I just cut them with a grinder but was looking for a faster and safer way once I start getting up above the 2nd floor. I've got about 50 or so flights left to do this year. right now when I have to replace the stringers I cut them in half with a grinder, pull the bottom section down, and then cut the top where they mount to the landing. and pull the top section off. its kinda dangerous doing it that way so I was thinking it would be way safer to just use plasma while the stringers are hung from something as to not fall as soon as they get cut. the problem being, I think it would be way more dangerous doing it with a short torch like my 30xp. vs a long torch connected to the 45xp so I wouldn't have to lean half my body out over a gaping hole. I already fell through once from the 3rd floor. not trying to do it again.
Reply:here is a picture (hopefully) of what I'm talking about. this is the second flight I did for this guy. I've done about 40 so far at this place now. anyway the old concrete comes off then the old stringers have to either get major repairs or I just toss them and build new ones. when I toss them the old handrail stays in place. (not my decision) and then new ones get put up. thats the easy part. the hard part is taking off all the broken stuff with out falling through since mostly every thing here is so bad I can't even step on most of the concrete treads while holding another concrete tread without fear of falling through again. Alot of the brackets are broke the stairs are crumbling and the stringers have giant holes in them.
Reply:Why not use a standard cutting torch?
Reply:I've already fallen through the stairs going up to the 3rd floor. the long torch would allow me to cut from the safety of the landing without having to outstretch over the hole. a normal torch I would have to grab onto the handrail (most of which is all crap and falling apart but the owner doesn't want to replace any of it until the city gets on him) and then stretch half my body out over the landing. If the handrail breaks or I have to catch a stringer I would be knocked off the landing.
Reply:This is a picture of the stairs I fell through. Its been about 6 months since then so the remaining stairs are getting really really bad.
Reply:Might want to think about a fall restraint harness when working in a stair well. My son picked up one that comes packed in a 5 gallon bucket with brackets and clips,just about everything you need. Found it at a local home center.Cost a lot less then a new system or just a torch. about $100. A lot less then a 600 to 800 torch.

Reply:im also just trying to find a faster solution. right now everything is done with a 7" grinder.
Reply:Originally Posted by Scrapman Industriesfall restraints may be good if you have someone to retrieve you. but after falling you have about 5-10 minutes to get pulled up before your passed out. around 15 your dead anyway. I work alone so id rather just take my chances with the ground. besides thats one more thing to trip on. plus add to that the fact that nothing in this place is sturdy enough to tie off to anyway.I actually started wearing a military style bump helmet when working at heights. If I had been wearing one the day i fell I would have just went back to work the same day. it actually will protect you in a fall unlike hard hats. plus you can attach all sorts of fancy stuff to it if you need something like lights ear muffs or what not.
