MIG OPERATION
•
High voltage danger from power source! Consult a qualified electrician for proper
installation of receptacle. This welder must be grounded while in use to protect the
operator from electrical shock.
•
Do not remove grounding prong or alter the plug in any way. Use only the supplied
adapter between the plasma cutter's power cord and the power source receptacle. Make
sure the POWER switch is OFF when connecting your welder’s power cord directly to a
properly grounded 230 VAC, 60 HZ, Single Phase, 50 Amp input power supply. Or, when
using the supplied 120V adapter, connect the 120V Adapter to a properly grounded 120V,
20 Amp input power supply.
1. POWER SWITCH - The power switch supplies electrical current to the welder. Whenever the
power switch is in the ON position, the welding circuit is activated. ALWAYS turn the power
switch to the OFF position and unplug the welder before performing any maintenance.
2. HOLDING THE TORCH - The best way to hold the welding torch is the way it feels most
comfortable to you. While practicing to use your new welder, experiments holding the torch in
different positions until you find the one that seems to work best for you.
3. POSITION OF THE TORCH TO THE WORK PIECE - There are two angles of the torch nozzle in
relation to the work piece that must be consider when welding.
a. Angle a can be varied, but in most cases the optimum angle will be 60 degrees, the point
at which the torch angle is parallel to the work piece. If angle A is increased, penetration
will increase. If angle A is decreased, penetration will decrease also.
b. Angle B can be varied for two reasons: to improve the availability to see the arc in relation
to the weld puddle and to direct the force of the arc.
c. DISTANCE FROM THE WORK PIECE - If the nozzle is held off the work piece, the
distance between the nozzle and the work piece should be kept constant and should not
exceed 1/4 inch or the arc may begin sputtering, signaling a loss in welding
performance.
d. TUNING IN THE WIRE SPEED - This is one of the most important parts of wire welder
operation and must be done before starting each welding job or whenever the voltage
setting or wire diameter is changed.
EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN!
Prolonged exposure to the welding arc can cause blindness and burns. Never strike an arc
or begin welding until you are adequately protected. Wear flame-proof welding gloves, a
heavy long sleeved shirt, trousers without cuffs, high topped shoes, and an ANSI approved
welding helmet.
