SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK CAN KILL.
•Turn the input power OFF at the weld- ing power source before installation or changing drive rolls and/or guides.
•Do not touch electrically live parts.
•Magnum™ Pro Fume Guns When inching with the gun trigger, electrode and drive mechanism are "hot" to work and ground and could remain ener- gized several seconds after the gun trigger is released.
•Welding Machines, Wire Feeders, and Fume Extraction
•Personal Protective
ment for welding, including but not limited to, safety glasses, hearing protection, protective footwear, weld- ing helmet, welding gloves, and weld- ing leathers.
•This product shall not be used in precipitation, or in wet or damp locations.
•Use these fume guns only with all consumable parts properly installed in place.
•Do not use these fume guns for
COMPATIBILITY OF WELDING MACHINES AND WIRE FEEDERS
1.If the welding process requires welding gas (FCAW- GS, GMAW, or MIG), then either the welding machine or feeder must be equipped with a gas solenoid valve to supply welding gas to the fume gun.
2.A gas mixer and regulator is required upstream of the gas solenoid valve to supply specified blends of welding gas at the specified flow rate.
PREPARING THE FUME GUN FOR WELDING
•Read all safety information: See the front of this instruction manual. Perform the following sections in the order shown.
Prepare the Welding Machine and Wire Feeder as follows:
1.Read all safety information in all related instruction manuals.
2.Disconnect input power to the machine and the wire feeder.
3.Machine and feeder polarity settings: Set to match the electrodeʼs polarity requirement per the instruc- tion manuals.
4.Gas selection: Connect gas supply to either the machineʼs or the feederʼs gas solenoid valve. Set the gas mixer (if required) to the specified gas com- position.
5.Gas flow rate: Set the supply regulator to deliver a gas flow rate of 50 to 70 SCFH thru the fume gun.
