Page 4: Safety
SAFETY DEPENDS ON YOU YESWELDER arc welding and cutting equipment are designed and built with safety. However, your overall safety can be increased by proper installation and thoughtful operation on your part. DO NOT INSTALL, OPERATE OR REPAIR THIS EQUIPMENT WITH- OUT READING THIS MANUAL AND THE SAFETY PRECAUTIONS CONTAINED THROUGHOUT. - Page 5 SAFETY WARNING CALIFORNIA PROPOSITION 65 WARNINGS WARNING: Breathing diesel engine exhaust exposes you to chemicals known to the State of California to cause cancer and birth defects, or other reproductive harm. Always start and operate the engine in a well-ventilated area. Ÿ...
- Page 6 SAFETY ELECTRIC AND MAGNETIC FIELDS MAY BE DANGEROUS. 2.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines 2.b. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before weld- ing.
- Page 7 SAFETY FUMES AND GASES CAN BE DANGEROUS. 5.a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone.
- Page 8 SAFETY CYLINDER MAY EXPLODE IF DAMAGED. 7.a. Use only compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the application and maintained in good condition.

Page 9: Installation
SELECT SUITABLE LOCATION Locate the MIG-250PRO in a dry location where there is free circulation of clean air into the louvers in the back and out the front of the unit. A location that minimizes the chance of dirt accumulation that can block air passages and cause overheating. -
Page 10: Safety Precautions
INSTALLATION SAFETY PRECAUTIONS Read entire operation section before operating the WIRE FEEDER WELDER. WARNING ELECTRIC SHOCK CAN KILL. Do not touch electrically live parts such as output terminals or internal wiring. Ÿ Insulate yourself from the work and ground. Ÿ Always wear dry insulating gloves. -

Page 14: Installing The Mig Gun Assembly
OPERATION INSTALLING THE MIG GUN ASSEMBLY • Attach the standard MIG welding gun to the EURO CONNECT on the front of the welder. GAS CYLINDER AND REGULATOR CONNECTION The gas cylinder (not supplied) should be located near the rear of the welder, in a well-ventilated area and securely fixed to the work bench or to the wall to ensure that it will not fall. -

OPERATION 12. Cut off the excess wire that extends past the end of the nozzle. 13. Fine tune the wire drive pressure with the pressure arm adjustment knob (G). a. Turn the wire drive pressure adjustment knob clockwise, increasing the drive pressure until the wire seems to feed smoothly without slipping. -
Page 17: Internal Thermal Protection
OPERATION INTERNAL THERMAL PROTECTION If you exceed the duty cycle of the welder, the thermal protection system will engage, shutting off all welder output. After cooling, the thermal protector will automatically reset and the welding functions can resume. This is normal and automatic behavior of the ma- chine, and does not require any user action. -
