WebMar 20, 2024 · Generally, as the contact tip-to-work distance (CTWD) is increased, the I 2 R heating effect is also increased, hence decreasing the welding current (I) required to melt the welding rod/ filler wire (in effect, increasing the deposition rate for a given current level).. Conversely, as the contact tip-to-work distance is decreased, the I2R effect is decreased, … WebNov 15, 2024 · Setup your shielding gas flow. Let’s go back to the valve on top of your gas tank for a while. Adjust the gas flow to about 15-20 cfh, which is suitable for MIG short-circuit mode. 17. Setup parameters on your welder. For MIG welding, you need to care about 2 parameters on the welder: Wire Feed Speed and Voltage. fmcsa safety audit help
