Staying busy help my club members with their rides. Newest work for our VP & his 85 720 Nissan ,full shave job & primer all out.
Truck Action... how do you set up your welder when you're welding on think steel like our trucks? i was welding some square tubes on the cab to place my amps on and my welds started burning through the metal.., so I then turned down the power as well as the wired feed speed and that seemed to help, but my welds looked a bit bubbly.. I then turned up the power a little bit up and that looked better, but I'm wondering what the right way is.. any light on the subject?
Sweet ride. I love 720's. Me and my buddy were making good progress on his but he sold the thing before we finished it.
if your welds are bubbly (porosity) there are a few things to check for. make sure your getting gas out the nozzle, the metal is clean of paint/primer, there isn't too much wind blowing. as far as the heat if your using a machine that has preset wirespeed and heat that is probably the main problem. you need to drop the heat and speed and make small welds. if your welding a heavier wall tubing (1/8") to sheetmetal you should start on the tubing and let the weld puddle up, then work it over until it fuses to the sheetmetal. doing short welds will help as well.
burnzya.. now that you mention it.. there was quite a bit of air.., that might have done it.. thanks for the advice.. I'm going to try again this week and see if I get improvement..
