MIG175 MIG WELDER Save this Manual You will need the manual for safety warnings and precautions, assembly instructions, operating and maintenance procedures, parts list and diagram. Keep your invoice with this manual. Write invoice number and date of purchase on the inside of the manual. Keep the manual and invoice in a safe and dry place for future use.
SAFETY WARNINGS AND PRECAUTIONS PLEASE READ AND UNDERSTAND THE FOLLOWING SAFETY HIGHLIGHTS. BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS. ARC AND TIG WELDING CAN BE HAZARDOUS. PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY. PACEMAKER WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING.
from the welder and work area before plugging in. Avoid starting unintentionally. Be sure the switch is in the off position when not in use and before plugging in. Do not carry any tool with your finger on the trigger, whether it is plugged in or not. Stay alert. Watch what you are doing. Use common sense. Do not operate any tool when tired. Check for damaged parts.
ELECTRIC SHOCK can be fatal The electrode and work (or ground) circuits are electrically “hot” when the machine is on. Do not touch these “hot” parts with your bare skin or wet clothing. Protective clothing should be hole free, dry and ANSI approved. Wear dry, hole-free gloves to insulate hands. Do not permit electrically live parts, cables, or electrodes to contact skin, clothing or gloves. This unit draws enough current to cause serious injury and or death.
ARC RAYS can burn Avoid eye and body damage. Arc rays and infrared radiation can cause injury to the eyes and burn the skin. Wear ANSI approved eye and body protection. Do not allow viewing by visitors without proper eye and body protection. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when plasma cutting or observing open arc plasma cutting.
ELECTRICALLY POWERED EQUIPMENT can be dangerous Turn off input power using the disconnect switch at the fuse box before working on the equipment. Install equipment in accordance with the local codes and the manufacturer’s recommendations. Ground the equipment in accordance with the manufacturer’s recommendations. MOVING PARTS can cause injury Keep away from moving parts such as fans. Keep all doors, panels, covers, and guards closed and securely in place.
SPECIFICATIONS GENERAL DESCRIPTION The LOTOS MIG175 is one of the most versatile welders. It is able to weld aluminum with the spool gun. Its transformer technology has been proven to be reliable and durable. MIG175 can easily connected to your existing 220V wall outlet and can be setup quickly within 10 minutes. It handles industrial standard 4” or 6” wire spools and incorporates resettable overload protection to assure long operating life. 175-amp MIG Welder with spool gun and mask, etc.

INSTALLATION PLEASE READ ENTIRE INSTALLATION SECTION BEFORE STARTING INSTALLATION. BE SURE THAT ONLY QUALIFIED PERSONNEL SHOULD PERFORM THIS INSTALLATION. __________________________________________________________________ BEFORE INSTALLATION ELECTRIC SHOCK can be fatal Have a qualified electrician install and service this equipment. Turn the input power OFF and unplug the machine from the receptacle before working on this equipment.
WIRE FEEDER INSTALLATION The wire feed drive roller attached to MIG175 has two wire grooves, one for 0.023” (0.6 mm) welding wire and another for 0.030 (0.8 mm) welding wire or 0.035” (0.9 mm) flux-cored wire. The factory default is the 0.023” (0.6 mm) wire groove. In the event that the 0.030” or 0.035” welding wire is to be used, the wire feed roller should be switched around. 1. Ensure that the MIG175 welding machine is powered “OFF” and the power cord is unplugged. 2.
HOW TO THREAD WELDING WIRE THROUGH THE WIRE FEEDER 1. Unlock the tension bar (1) on the wire tensioner and lift up the rocker arm (2). Insure that the wire drive wheel is appropriate to the welding wire size, see above describing the installation to wire feed roller installation. 2. Pull out the welding wire (3) from the welding wire spool carefully. NOTE: Do not let go of the wire prior to step 5 or the entire spool will unravel and be useless. 3.
SHIELDING GAS INSTALLATION A compressed gas cylinder containing 75% Argon and 25% CO2 should be used when using the MIG (GMAW - GAS Metal Arc Welding) on steel. Use pure argon when welding aluminum. The flow regulator and supply hose is included with your welder. Compressed gas can be obtained from your local welding suppler. 1. Attach the compressed gas cylinder with a chain to a wall or other secure object, to prevent the cylinder from falling. 2.
OPERATION PLEASE READ AND UNDERSTAND THIS ENTIRE SECITON BEFORE OPERATING YOUR MACHINE. ONLY QUILIFIED PERSONNEL SHOULD OPERATE THIS EQUIPMENT. OBSERVE ALL SAFETY INFORMATION THROUGHOUT THIS MANUAL. WELDING OPERATIONS ELECTRIC SHOCK can be fatal Have an electrician install and service this equipment.
WELDING PROCESS 1. Please refer to “Welding Label” in the unit and select proper setting based on the variety of metals and their thickness. 2. Adjust output polarity according to the welding wire and to ensure whether or not the protective gases are needed. 3. Connect the ground clamp to work pieces that are to be welded. This connection should be good and secure. Your welding torch should have clear access to the work piece. 4.
OVERLOAD PROTECTION Overload protection for power supply to welding Your MIG175 is equipped with a temperature controller as well as an overload breaker. These two protection devices will protect the welding machine whenever the output exceeds the maximum out-put. If the output is exceeded, the unit will not supply voltage and the wire feeder will shut down (the fan will continue to run to cool the unit).

Basic Gas Troubleshooting Guide 1) Switch the machine on. If the fan is not on check the Voltage to make sure it meets the requirements of the welding machine and that it is properly secured and grounded to the power supply. 2) Check that the gas is properly secured to the machine. Also check that all gas connections (hose) and regulator are connected. The type of gas needs to be compatible with the specification of the MIG175 welder which varies depending on the metal material you are working on.
