Welding With Car Alternator

Personally I always disconnect the battery alternator when Im having welding done. Alternator welder wiring diagram wiring diagram is a simplified conventional pictorial representation of an electrical circuitit shows the components of the circuit as simplified shapes and the capacity and signal friends amid the devices.

If it works for welding it is a 3phase excited coil altenator to use it for this purpose you must either have a older model with a external regulator or bypass the regulator inside.

Welding with car alternator. I now remove the battery leads and the alternator plug. Many people believe the negative terminal should be disconnected but cannot explain why it should be done. Gm 1 wire 100 amp.

Dodge Pickups 1994-2003 195 amps Gas Diesel - High Output Welding Alternator. Welder from Car altenator. We just went through the blown diode after welding on the vehicle with the batteries connected thing on my buddys 4x4 a few weeks ago after he built a new winch mount.

Modern vehicles use a control circuit which regulates the voltage in and out of the alternator to prevent over charging. Better and stronger welds given the same power input. Further action with the welder has been ok.

With that unpleasantness out of the way it is highly likely that the voltage current applied by the welding gear has damaged the low voltage control electronics responsible for operating the alternator. To use your alternator as a welder you have to attach the welding cables to the back of the alternator. Most cars have an alternator that produces about 60 to 80 amps at 2000 engine rpm which is much faster than idle speed.

The reason to do it is that it helps to prevent damage to the vehicles ECU and other electronics. WELDERS DC 2 POLES WITH SCR 35500A - 4kVA12kVA 50Hz AND 60Hz This welder-generator is designed to manage and control the operation of a dedicated low voltage three-phase alternator to perform the MMA welding functions of the charger and Starter if it requires you to put in motion a vehicle having no battery charge enough to do it. I welded a TR7 and ended up having to replace the alternator.

I think I would still disconnect the bolts just to be sure. The ground lead is attached to the negative pole of the alternator and the positive lead connects to the welding electrode or stinger as its often called. Unlike other onboard welding alternators our CS144 can replace your current unit.

Yep disconnect the battery and Id probably disconnect the wiring on the alternator this time around although I dont when welding further away. No need to purchase or fabricate a complicated bracket. I have never bothered to disconnect anything when welding on a car and during 20 years of welding have never had any kind of problem.

Alternator Welder I also added a diagram at the end. Dodge RAM 2500 3500 4500 5500 - High Output Welding Alternator. Alternator welder wiring diagram.

But thats with a quick block connector thing. I am not an engineer. Therefore this is what I was after.

Just idling the engine the alternator only puts out 30 to 40 amps and those amps must run muiltiple things in the car so maybe theres less than 20 amps available to keep the battery charged and supply an inverter. Speculation runs rife regarding whether the negative terminal of a vehicles battery should be disconnected before welding on that vehicle. The CS144 is drop in compatible with hundreds of vehicles and can be adapted into hundreds more with simple prefabricated bracket.

I can confirm that leaving the alternator connected when welding can destroy the diodes. Chrysler for 60s 70s Early 80s 180 amp - High Output Welding Alternator. Only takes a few moments and its piece of mind.

Ignition system puts out what 20000 volts and does that fry the alternator. Saw this before on a 4x4 forum. You have to see it to believe it.

It makes a 100 Amp high-frequency alternator welder equivalent to a 140 Amp ordinary AC arc welder. I have heard welding a no no and others say it is OK if you take precautions of not holding the arc for only a few seconds and twisting the leads will lessen the danger I was a welder in my ocupation only weld occasionally now I know some out there still weld like to hear their experience I like your opinion on alternators it about matches my. In the alternator welder the current level cycles up and down and produces frequencies in the hundreds or thousands per second.

Yes our 150A and 200A power generators can replace an existing alternator -- when equipped with an appropriate external voltage regulator. Welding by hwilli2134 - 2020-02-17 181707. Sep 16 2008.

Startermotor draws up to 500 amps and that current goes through the body on most vehicles. And yes either model will deliver its full rated welding power for battery charging in a 12V vehicle electrical system at any desired charging voltage between 12-15V.
