Hi everyone, just wanted to ask a few questions since all of you seem very helpful. Let me start by saying I have no idea what im doing when it comes to electrical work. I picked this welder up super cheap and was told to replace the plug and that's it but I want to be certain everything is good before I go and buy the part to replace it. 1. Is this the correct size of power wire for this machine? reads 3/C 10 AWG SOOW
2. Is this wired correctly to the switch on/off switch? And is there any specific way to attach the other end to the plug? Green of course is ground, but the other two circled wires, does it matter which way they go on the plug?
3. Is this the correct placement for the ground wire? and what are these circled wires for? they appear to be taped from factory... I couldn't find any writing on them.
I understand these are probably bonehead questions, im very inexperienced and having a hard time finding answers by searching the web.The diagrams inside the machine are also faded and partially unreadable. Thanks
Reply:Cord size tells me it might be wired for 460 volts. Line current depends on if it has PFC capacitors or not. on 240 volts, 250 amp load it will draw 68 with pfc and 86 with out. 10 awg wire is only good for 30 amps. this wire will be ok for first testing to around 100 weld amps. on 240 volts. If you never go over 200 amps you can use 6 awg wire. just check the cord after welding and see if it gets hot. couldn't tell from the picture of the line switch which wires were connected to it.H1 is connected to the switch. H2 and H3 are your two different line voltages.use H2 for 240 volts and H3 for 460 volts. Tape up real good the one that is not used. The 460 connection will have 460 or more volts on it when you are connected to 240 volts. To get an owner,s manual go to Lincoln's wed site and under the resources tab select parts. then enter as a guest. IF you have the code number from the front plate enter it in the box. IF not, select the button to the left of the code number box and a page of pictures will open up. Then open the stick welder file and find your welder or one that like like it. They didn't make many changes the this design. The last version they went to a square case. very little changes to how they are wired. Except there are two main versions. AC only and AC/DC welders.
Reply:10 gauge wire is too small. It really needs 6 gauge SOOW, based on the current that machine draws. I have 6/3 SOOW on mine. You should also be using 6 gauge wiring for your outlet, with a 90 amp fuse. It looks like it is correctly connected to me. I believe those wrapped up wires are for the power factor correction capacitors, which I am guessing are not installed on your machine.Miller Multimatic 255 |
