Frequently Asked Questions
A safety-conscience welder should never leave the work-area with their welding set turned on and, in particular, with their welding torch carelessly laid on the bench or workpiece. This is because the trigger of a MAG welding torch can easily become pressed, causing filler wire and sheilding gas to feed continuously. If this happens, a reel of wire may be completely discharged and wasted. Or, a loop of wire may be discharged and then contact the workpiece or bench, at which point, rapid resistance heating of the wire loop takes place to create a dangerous ignition source which can easily start a fire. Some gases used for welding are completely inert and, if allowed to collect, can be extremely dangerous if inhaled.
