07:35 Why Did It Happen?
Kevin Caron shows his first Everlast welder, which he got back in 2015. They don't make them anymore, but it's been a real workhorse. It's the Everlast MTS 251si, a MIG, TIG stick welder, or multiprocessor machine.
But lately, after 1, 1-1/2 hours of welding the welder would over temp. There'd be a warning on the control panel, and then it'd shut down. Let it cool down, and it would fire back up, but only for a minute or two and then would overheat again. It wouldn't cool itself off anymore.
DIAGNOSING THE PROBLEM
Tech support said it could be the control board going bad or 1 or both fans. To test this idea, Kevin Caron fired up the welder, ran it until it overheated, and let it cool off enough that it would come back on again. When he put his hand over the cooling fans the bottom fan seemed to be drawing a lot more air than the top fan. The fan had either gone bad or was going bad. Even though it was still turning, it didn't seem to be turning up to speed. Kevin Caron ordered 2 new fans and a new control board.
INSIDE THE MACHINE
Kevin Caron has the handle and case off the machine. He shows the front of the welder and points out the high frequency board for TIG welding - that's where the adjustable points are. Then he identifies the machine's 2 main boards, which run 99% of the welder. He points to the old Cooling System Control Board - he ordered a new one. He shows where the wire goes through the machine's chassis into a double plug, which plugs into 1 of the control board terminals.
CHANGING THE PARTS
Kevin Caron releases a red and a black wire, popping them out to make room for the new ones. Then he snakes them down, installing each new fan, starting with the bottom one. He uses a jeweler's screwdriver to reach down inside and open the little catch on the wire. If you push down those two catches, the other wires pop out. On the new fan. he's already picked up the tabs so they'll click in the place when he puts them inside the plug.
He'd also already marked the plug, so the black wire goes to the black mark that he put on the plug. He clicks everything back into place and sets the control board in its place temporarily.
Kevin Caron then shows how to replace the 2 fans - check out this free how to video for the details of wiring, spacers, etc., tightening everything to snug but not overtight, including putting the control board panel into place.
Next he shows the gasline, which is a clear hose with a stainless fitting. It goes up against the inside of the bulkhead, and then there's a brass fitting that goes on the outside of the machine, where your gasline hooks to the bottle. Kevin Caron hooks up 1 last connector from the control board. Next is replacing the screws on the back and on the cover and top to put on the handle. Then he can set up the welder and weld with it to find out if the fix worked.
WHY DID IT HAPPEN?
But aren't Everlast machines are practically bulletproof? What went wrong?
Kevin Caron said the welder has been very, very good but the studio is not air conditioned, so it's often 95 - 110 degrees inside. Most of all, if someone tried to blow out the dirt inside the machine - something you need to do with low pressure air - by just shooting air from the compressor (we're talking 120 psi) it can spin the fan up higher than it was ever meant to turn and you can burn the brushes out of it. That's what Kevin Caron think happened.
You got to be good about cleaning inside these machines or the dust will act like an insulator on the electrical components and burn up the brushes.
