It's hard to tell you what to expect without knowing specifics about the test. Will they be asking you to weld thin sheet metal,or thick steel plate? What shield gas will they have you using? 9_9 I hesitate to even call the gas-less flux core process "welding." There isn't a lot of comparison to be had with either MIG, or gas-shielded flux core ("dual shield") which are what professionals use. The only thing that can be said about gasless flux core it is it produces consistently weak, faulty, awful-looking welds. Also it tends to be equipped on severely underpowered no name welding machines made in "laughganistan." Welds made with this process tend to resemble vulture droppings. I've heard that John Deere is a company that actually knows crap about welding. I may be wrong. With low current, "short circuit" MIG it believe it's wise to "drag" the weld. But If you're welding sheet metal thickness >1/8" it doesn't matter too much. Ask the person supervising the test what settings to use. Make it sound like you're not totally clueless. "what does the WPS sheet say the parameter settings should be for this?" Use the words "WPS sheet" and "parameters." That's engineering jargon. If a supervisor at a company isn't willing to tell a welder what settings to put on his machine, you may be better working somewhere that has proper mangement.
