I have to weld in a new front trunk pan replacing the hole left from an AC unit. I have taken two MIG classes. Beside being a newbie, I have other limitations to consider.
I don’t have access to a 220 line. I’m inexperienced. It would cost me $1000 to have it professionally done. And I don’t want to buy a bunch of equipment for one job. Can I use a flux welder? There a couple cheap units at Harbor Freight (under $150) on sale right now. What don’t I know that I should know? Thanks (IMG:style_emoticons/default/welder.gif) |

Looked up what is on sale
Definately don’t get this one. Only current control is a single min/max switch.  This one at least has variable wire speed and variable current controls. Duty cycle is pretty low at 30% @ 90A but would work in a pinch. Looks like a smaller inverter type unit - meaning no big heavy transformer but slightly more fragile. This has complicated power electronics, and if anything fails, it is a throwaway unit.  Still would recommend a better used unit that can support shielding gas but wanted to see what was being offered by HF. |
