I bought this welder 6-7 years ago and used it on a few small projects. I went to use it recently and the welds would not penetrate. The wire feeds, just can't get the welds to penetrate. I don't know what the problem is and don't have time to mess with it. Bought this thing for right around $400 back then. Thinking this would be valued at $100 or so in its current state. Would like to trade it for something of the following: Ammo (5.56, 45 acp, .308) Project guns like a fiixer upper 10/22, remington 870, etc (can have rust, just no pitting) can add cash for the right trade. Open to other firearm/ ammo trades, just name what you got. Worst I can say is no.
