Wear a safety harness if working above ground. -Do not drape cables over or around your body. -Wear a full coverage helmet with appropriate shade (see ANSI Z87.1 safety standard) and safety glasses while welding.
  • Page 5 -Always use a helmet that covers your full face from the neck to top of head and to the back of each ear. -Use a lens that meets ANSI standards and safety glasses. For welders under 160 Amps output, use a shade 10 lens;...
  • Page 6 -Do not wrap cable around your body while welding. -Wrap MIG gun and ground cable together whenever possible. -Keep MIG gun and ground cables on the same side of your body. Shielding Gas Cylinders Can Explode High pressure cylinders can explode if damaged, so treat them carefully. -Never expose cylinders to high heat, sparks, open flames, mechanical shocks or arcs.

    in real time. 1.11.2. Overvoltage protection: When the input voltage is below or Above the specified voltage, the machine will cut off the power to protect itself until the Proper input voltage is available . INSTALLATION 1. POWER REQUIREMENT - AC single phase 230V, 60 HZ with a 50 amp circuit breaker is required. DO NOT OPERATE THIS UNIT if the ACTUAL power source voltage is less than 220 volts AC or greater than 240 volts AC.

In this mode the operator can press and release the torch trigger and the output will remain active. To deactivate the power source, the trigger switch must again be depressed thus eliminating the need for the operator to hold the torch trigger.

    3.5 SELECTING THE PROPER ELECTRODE There is no golden rule that determine the exact rod or heat setting required for every situation. The type and thickness of metal and the position of the work piece determine the electrode type and the amount of heat needed in the welding process.
  • Page 18 3.7.1 Holding the electrode The best way to grip the electrode holder is the way that feels most comfortable to you. Position the Electrode to the work piece when striking the initial arc it may be necessary to hold the electrode perpendicular to the work piece.
  • Page 19 Stringer Bead Weave Bead The weave bead Used when you want to deposit metal over a wider space than would be possible with a stringer bead. It is made by weaving from side to side while moving with the electrode. It is best to hesitate momentarily at each side before weaving back the other way.
  • Page 20 3.7.6 Finish the bead As the coating on the outside of the electrode burns off, it forms an envelope of protective gases around the weld. This prevents air from reaching the molten metal and creating an undesirable chemical reaction. The burning coating, however, forms slag. The slag formation appears as an accumulation of dirty metal scale on the finished weld.
