I am looking at buying a cheap arc welder to have around the house. Any suggestions??? I have my eye on a Chicago Electric Arc-140 Welder from Harbor Freight for ~ $80. The specs are : input power 115/230volts AC; welding current 30-140 amps. Anyone have this??? I am very novice when it comes to welding and the budget is very limited right now. I plan to repair the shock mount on the front axle that appears to be cracked and going to give out on me any day now. In the future, the plan is to bulid my own roof rack. Will this welder cut it ?
