Next make-up a 1 1/2 foot or so long cable with another female twistlock welding connector on one end and a terminal lug on the other end, then attach the terminal lug to the connection point on the wirefeed drive block that you disconnected the positive supply cable from. You could disconnect the positive cable that is attached to the wirefeed drive block and install a female twistlock welding connector to this lead. On the front panel there is a twist plug type of receptacle that the ground cable is attached to that is supplying the Negative connection for the ground cable. The block where the wirefeed drive rolls are located is an isolated piece and has a cable attached to it that is supplying the Positive power. Being a tinkerer by nature however I do believe that you could in fact do a few modifications to change that. Hello again ahall13, when I looked at the various pictures that you posted, they indicate that this machine may not have been originally designed to have the polarity changed. You know, the settings!!! Did you happen to see if there was a manual around for that equipment? Once you get those to us ,we can help you set the machine up so that you can see if it works or not? Have you tried to strike an arc with it yet even though you do'nt have a bottle of gas yet? I look foward to your response :) Respectfully, Henry In other words, i want you to take a picture of the machine form the front where the mig gun is hooked up to and where the on/off switch, all of the knobs and buttons are. Is there a possibility that you can take a picture or two of the front and back of this machine? I ask this because, the pics you have are showing the sides of the machine and it's guts with the exception of the top side view of the drive roll mechanism. at this point, move down to where the transformer and the rest of the "Guts" that make up the power source but, do'nt start the machine yet!!! In fact either disconnect it from the plug or fuse box first for safety's sake!!! Then clean the insides because you've got alot of dust built up inside!!! If you have access to a shop-vac wet/dry vac cleaner use that first then, if you cannot remove the rest, use compressed air at no more than 60 psi but, make sure you do'nt blast any type PC-board if you can because the electronics are rather sensitive so in that case, use the vac instead. After that secure those black cables so that they do'nt get in the way of the wire that's going to be fed. Regards, aevaldįirst of all, I'd like to echo Larry's "Weldcome"!!! Next, before you even start to use the machine you've got there You've got to clean it up!!! Dust is the enemy of electrical equipment regardless of what it's used for!!! Please clean the area where the wire feeder/drive rolls are. Good luck on your welding experimentation and don't hesitate to ask questions in the future. Most gasless fluxcored wires will having a starting stickout of around 1/4" and extend up to around 1 1/4" or so, depending on wire diameter. With the gasless fluxcored wire pay attention to the stick-out of the wire(distance the wire extends past the contact tip to where it forms the bead as welding is progressing) as suggested by the wire manufacturer and use a backhand method for welding with this particular process. these changes are many times done under the cover where the feed mechanism is housed. For using the machine with the gasless fluxcored wire you will need to connect the welding gun to the - side of the output terminal and the ground will need to be connected to the + side of the output terminal. With a machine that can run GMAW and gas-shielded FCAW(dualshield), the welding gun will be connected to the + side of the machine output and the ground will be connected to the - side of the output of the machine. Most machines that are capable of being used for GMAW, gas-shielded FCAW, and gasless FCAW will have provisions for changing the polarity of the output of the machines. When he referred to the polarity of the machine when using the gasless fluxcored wire you will need to pay close attention to this. He gave you a very concise response for getting started with your machine. Hello Adam, as Lawrence said, welcome to the forum, and also, as usual, Lawrence beat me to a response.
