Page 3: General Welding Safety Instruction
INTRODUCTION This User’s Guide provides specific information about your EasyMig Welding System. This guide provides pertinent information needed to safely and effectively use your Welding System. The information in this manual applies to specific EasyMig Welding System models. It gives instructions on set-up, installation and actual use of your EasyMig Welding System. - Page 4 PERSONAL PROTECTION 1. WEAR closed, non-flammable protective clothing, without pockets or turned up trousers. 2. WEAR a non-flammable welding helmet to shield the neck, face and sides of the head. Keep the protective lens clean. Replace the protective lens if broken or cracked. Position a transparent glass between the lens and the welding area.
- Page 5 VENTILATION WARNING Ventilate welding work areas adequately. Maintain sufficient air flow to prevent accumulation of explosive or toxic concentrations of gases. Welding operations using certain combinations of metals, coatings and gases generate toxic fumes. Use respiratory protection equipment in these circumstances. BEFORE welding, read and understand the Material Safety Data Sheet for the welding alloy.
- Page 6 ●FUMES, GASSES AND VAPORS CAN CAUSE DISCOMFORT, ILLNESS AND DEATH! Reduce the risk of discomfort, illness or death Read, understand and follow the following safety instructions. Additionally, make certain that anyone else who uses this welding equipment, or who is a bystander in the welding area, understands and follows these safety instructions as well.
- Page 7 techniques should ALWAYS be present in the working area. If a person is unconscious and electric shock is suspected, DO NOT touches the person if he or she is in contact with cables or electric wires. Disconnect power from the machine, and then use First Aid.

- Page 10 POWER SOURCE CONNECTION Power Requirements This welder is designed to operate on a properly grounded 220 volt, 50/60 HZ, single-phase alternating current (AC) power source fused with a 50 amp time-delayed fuse or circuit breaker. (Please consult local codes for proper plug and receptacle applications.) A qualified electrician should verify the ACTUAL VOLTAGE at the receptacle into which the welder will be plugged and confirm that the receptacle is properly grounded.

Page 13: Operation
WELDING TIPS 1. Keep the torch handle at 45° angle with respect to the work piece. Maintain the nozzle about 1/4” (6 mm) from the surface. 2. Move the torch handle with a careful and steady movement. 3. Avoid welding in areas with too much air movement. The air blows away the shielding gas from the weld pool and causes porosity in the weld. - Page 14 Range of welding current and voltage in Short Circuit Transition and granular Transaction Short circuit transaction Granular Transition Wire Ø (mm) Current (A) Voltage (V) Current (A) Voltage (V) 40-70 17-19 160-400 25-38 60—100 18-19 200-500 26-40 80-120 18-21 200-600 2T—40 100—150 19-23...

Page 15: Speed-Read Table
SPEED-READ TABLE Weld condition setting directly influences the stability of the weld course and the weld. In order to obtain the good weld, the welding current and welding voltage should be set optimally. Generally, the setting of weld condition should be according to the welding diameter and the melting form as well as the production requirement. - Page 16 Parameter for Fillet Welding in the Vertical Position (Please refer to the following figure.)

Page 18: Daily Check
DAILY CHECKING To make best use of the machine, daily checking is very important. During the daily checking, please check in the order of torch, wire-feeding vehicle, all kinds of PCB, and the gas hole, and so on Remove the dust or renew some parts if necessary. To maintain the purity of the machine please use original welding parts. - Page 19 3. Make sure that there is no otherwise unstable arc bending or elongation of wire possibly presents. feed tube. 2.
