INSTALLING MIG GUN INTO A FEEDER
GENERAL SAFETY
Before installation or operation of T-Gun MIG Guns, please read the safety precautions listed below.
1. Always wear a properly fitted welding helmet with the proper grade of filter plate and suitable welding gloves.
2. All exposed skin should be covered with flame resistant, protective clothing. DO NOT WEAR CLOTHING MADE
FROM FLAMMABLE SYNTHETIC FIBERS.
3. Protective screens or barriers should be used to protect others from spatter, flash and glare while welding.
4. Prevent fires by ensuring that hot slag or sparks do not contact combustible solids, liquids or gases.
5. Ensure that operator’s head is not too close to the arc and that adequate ventilation is available.
6. Constant repetitive motion may lead to cumulative trauma disorders.
7. Do not touch live electrical parts. The following should be checked to prevent electrical shock:
Equipment is adequate for the job, properly grounded and installed according to code.
Faulty or damaged equipment is repaired or replaced.
Proper operator maintenance is performed to prevent excess spatter accumulation in the nozzle, or the
contact tip or other areas of the gun.
Electrical insulating components are in place and not damaged. Repair or replace if necessary.
Operator and his surroundings are not wet.
Cables are not wrapped around operator’s body.
Equipment is off when not in use.
