Picked up a used 180SD on Craigslist for a decent price. Box looks almost brand new, showed 7h8m and 1031 arc cycles. Get it home, get the tank filled and start (trying) to weld with it. It's acting crazy. Wants to only give me HF but not throw an arc. Fiddle around with it some and it finally thows an arc and seems to weld like it should then after about 30 seconds it starts stuttering/making a thumping sound and goes out. Then more HF/no arc. Now I keep getting HLP-1 in the mix of all this. I'm hoping I didn't get swindled. Haven't tried stick yet, just got it online last night and was frustrated. Made sure all connections for the torch and ground were tight. Basically everything outside the welder seems in order.
I'm hoping it isn't the PC board, but I'm going to dig into it today. Any troubleshooting tips? The book isn't too helpful for troubleshooting. Says to take it in. I'd really not like to spend a hundo finding out it needs $900 board. I have pictures of it and a short clip of the way it is welding if you want to see it, just LMK. Thanks in advance for the help. I'm an electrical engineer so I plan to tackle the board repair myself before replacing it. I was born for this is suppose.
SN: LC300516 Late 2002 model I think.
