Profusion heater off welder plug?

[tom-ky]

Is the any way that one of these:

Could possibly be used off a 50 amp 220 plug? Is there any type of device that would give you the circuit protection needed?

Looking for a way to possibly run a couple of these just for some heat in a 30 x 40 garage.

4800 watts is like 21 amps at 220 volts. One should be fine on a 50 amp circuit. Two might be ok as well, but I would probably put each on it's own breaker myself.

I have 2 welder plugs on separate circuits on each end of the garage. Guess what I am saying is there a safe way to adapt from the welder plug and have the proper 30 amp protection. Didn't think it was a good idea just to change the plug and run it off the 50 amp breaker.

Why not? The circuit protection is for your wires in the wall and the plug. I would just change that end to match your receptacle. You would be drawing less than 50A, so your wiring is safe. As far as the unit itself, it should have its own saftey device, and if not, you may be able to add something if you had to.

If you have two separated welding outlets why not change one to a heating outlet? Switch the breaker and the socket in the wall so you dont plug your welder into a 30a breaker.

I just need to be able to weld on either end of the garage so that is not an option.

You can just change the plug and run it. The breaker is to protect the wiring circuit, not the device. The heaters themselves have overheat protection built into them. Even if the heater was drawing 50 amps (which it won't) it wouldn't matter because the circuit is setup for it. I'd just change it over to the 50 amp plug and use it. Mine just has a 50 amp range cord with a receptacle on the ceiling and a 40 amp breaker with 8 gauge. It's the 7500 watt version. I didn't want to hard wire it because it will be leaving with me when I move.

Some devices depend upon the rating of the branch circuit ocp to protect it. Unless the mfr's instructions specify a larger ocp value is acceptable, you cannot just chop off the plug and put something else on. That's how bad things can happen!

I have the same unit and I did (not correct or legal) cut the end of the heater and put on a 50 amp end to use my welder outlet to run it. But I only run it when I am out there and I have a 20 LB fire extinguisher a few feet away mounted on the wall, if something does go wrong it should be at the unit as thats the weakest link in the chain. For me its a temp solution till I get a separate line pulled from the basement for a hard wired wall mounted permanent electric heater.
One alternative could be putting in a small sub panel where one of your outlets is and then running a plug for both with there own circuit breakers. Kinda a pain but its a permanent solution (not sure whats allowed by code if you could put a 50 amp sub panel there on existing wire) .

Buy 2 of these off of eBay.

Carefully make appropriately sized holes for the handles and mounting holes on the side of the cabinet. Install the 2, side by side and connect the handles with a small machine screw.

Install your 50A plug and you are safe.

I just hung a profusion, they're meant to be hard wired so I don't see why you couldn't put a welder plug on it. Should be pretty simple. I thought about it but I don't weld so I don't really need it.

The one I am considering is not hard wired.

Oh never looked at your link. Any reason you don't just buy this one?

Put whatever plug you want on it.

Didn't know if it was ok to hardware one of those. Also thought since they where made to be hung that it might blow the heat on the floor. Didn't want to hang one as I wanted to be able to use it on different areas.

The 5000W like Bolson has and the 7500W like I have are nearly identical. They both made to be hard wired. I didn't want to hard wire mine because I wanted to make it easily removable and I think it looks cleaner with the outlet on the ceiling rather than just running 8 gauge romex through the ceiling down to it. I think the reason they say it's technically illegal to not hardwire it is because they don't want someone unplugging it when it's on and creating an arc. I get that they don't want you cutting cords off things and changing the ends, but if it's properly done and you're going to a heavier duty cord and receptacle I'm not sure what the problem is.

I get wanting to move it around, but I think you'd also be happier to just have something that's out of the way and works. I hated having to move my heaters around because they were on the floor.

I'm also pretty sure I've read that plenty of people just use them as portables. No reason you couldn't, can move the louvers to blow up, doesn't get terribly hot. Honestly it's probably the exact same heater as the one you linked but it's got a few more features, thermostat, adjustable wattage, etc. And the price is almost identical.
