Overall Weight: 35 lbs. MIG welding (sometimes referred to as gas metal arc welding, or GMAW) is a process that requires the use of a nozzle, as it uses a shielding gas. However, 75/25 shielding gas does not come without its kinks. And these welders can also weld flux core. 10 per cent Ar + 85-90% He + 2-5 % CO2) increases the amount of helium as you increase the flow. Put the contact tip back on. . Smooth arc starts with minimal spatter. For . Sure enough, if I close the tank valve and pull the trigger, it's not bleeding off the . Gas MIG Welders are good for welding thinner materials, such as sheet metal. Check everywhere if the gas is leaking or not; gas leakage before welding is not suitable. The top reasons for MIG welder sputtering are: Dirty welder components. They are installed where the wire goes into the drive roll and where the wire goes out of the drive roll into the gun. C $255.75. Next, loosen the nut/wing nut that clamps the whip into the block and pull out the whip. Set the flow rate to around 20-25 cubic feet an hour and make sure that the gas is switched on. MIG Welders That Can Weld With No Gas. Maintain a slow speed which has a lower thermal for metals. MIG weld 24 gauge up to 3/16 in. Using a backhand technique or a drag angle, you may risk getting serious porosity and get a poor weld. With DCEN, the negative terminal inside your machine is hooked up to your electrode (your MIG gun) while the positive terminal is hooked up to your . So, for gasless MIG welding polarity (when using flux core wire), your MIG welding polarity settings should be set to direct current electrode negative (or DCEN). Current: 270 A - 550 A. If the weld surface and the ground clamp area are clean you should be able to start an arc if all of the above things are ok. Dirty wires. Also be sure the spool feeds the wire from the bottom. It's common for people who stick weld to allow too much stick out when MIG welding. If blowing compressed air (backwards--remove gas line) thru it does not solve the problem, contact Hobart Tech Support on Monday and they'll have a new one in the mail to you in no time.
