Installation and Operator Instructions

Read this entire section before installation or operation of the machine.

Location and Environment
This machine will operate in harsh environments. However, it is important that simple preventative measures are followed to assure long life and reliable operation:

• Do not place or operate this machine on a surface with an incline greater than 15° from horizontal.
• Do not use this machine for pipe thawing.
• This machine must be located where there is free circulation of clean air without restrictions for air movement to and from the air vents. Do not cover the machine with paper, cloth or rags when switched on.
• Dirt and dust that can be drawn into the machine should be kept to a minimum.
• This machine has a protection rating of IP23. Keep it dry when possible and do not place it on wet ground or in puddles.
• Locate the machine away from radio controlled machinery. Normal operation may adversely affect the operation of nearby radio controlled machinery, which may result in injury or equipment damage. Read the section on electromagnetic compatibility in this manual.
• Do not operate in areas with an ambient temperature greater than 40°C.

Duty cycle and Overheating
The duty cycle of a welding machine is the percentage of time in a 10 minute cycle at which the welder can operate the machine at rated welding current.

Example : 60% duty cycle

The machine is protected from overheating by a temperature sensor. Excessive extension of the duty cycle will cause the thermal protection circuit to activate. The image is shown by the display [7].

Input Supply Connection

• WARNING Only a qualified electrician can connect the welding machine to the supply network. Installation had to be made in accordance with the appropriate National

• Only a qualified electrician can connect the welding machine to the supply network. Installation had to be made in accordance with the appropriate National

• Electrical Code and local regulations. Check the input voltage, phase and frequency supplied to this machine before turning it on. Verify the connection of ground wires from the machine to the input source.

WARNING
Positive (+) polarity is set at the factory. Before welding check the polarity for using electrodes and wires.

• If the welding polarity has to be changed, user should:
• Switch off the machine.
• Determine the wire polarity for the wire to be used.
• Consult the electrode data for this information.
• Take off the terminal block’s shield [17].
• The tip of the wire on the terminal block [18] and work lead fix as is shown in the Table 1 or Table 2.
• Put on the terminal block’s shield.
• The machine must be used with the door completely closed during welding.
• Not use handle to move the machine during work.

Loading the Electrode Wire

• Turn the machine off.
• Load the wire spool [16] on the spindle [20] such that the spool turns anticlockwise when the wire [15] is fed into the wire feeder.
• Put on the wire roll using the correct groove corresponding to the wire diameter.
• Free the end of the wire and cut off the bent end making sure it has no burr.

WARNING

• Sharp end of the wire can hurt.
• Insert an electrode wire into welding gun.
• Adjust force of pressure roll of the wire feeder properly.

Wire Spool Loading

WARNING
Turn off the power source while mounting a wire spool.

• Turn the machine off.
• Open the left side panel.
• Unscrew the Locking Nut [21] and remove it from the Spindle [20].
• Place the spool [16] on the Spindle [20] making certain the Spindle Brake Pin [22] is put in the hole in back side of spool..

WARNING
Position the spool so that it will rotate in a direction when feeding so as to be de-reeled from bottom of the spool.

• Re-install the Locking Nut [21]. Make sure that the locking nut is tightened.

Adjustments of Brake Torque of Sleeve

• To avoid spontaneous unrolling of the welding wire the sleeve is fitted with a brake.
• Adjustment is carried by rotation of its Allen screw M8, which is placed inside of the sleeve frame after unscrewing the Locking Nut of the sleeve.

21. Locking Nut.
23. Adjusting Allen screw M8.
24. Pressing spring.

Turning the Allen screw M8 clockwise increases the spring tension and you can increase the brake torque Turning the Allen screw M8 anticlockwise decreases the spring tension and you can decrease the brake torque. After finishing of adjustment, you should screw in the Locking Nut again.

Adjusting of Force of Pressure Roll Force
The pressure arm controls the amount of force the drive rolls exert on the wire. Pressure force is adjusted by turning the adjustment nut clockwise to increase force, counterclockwise to decrease force. Proper adjustment of pressure arm gives the best welding performance.

WARNING
If the roll pressure is too low the roll will slide on the wire. If the roll pressure is set too high the wire may be deformed, which will cause feeding problems in the welding gun. The pressure force should be set properly. Decrease the pressure force slowly until the wire just begins to slide on the drive roll and then increase the force slightly by turning of the adjustment nut by one turn.

Inserting Electrode Wire into Welding Gun

• Turn the welding machine off.
• Depending on welding process, connect the proper gun to the Euro Socket, the rated parameters of the gun and of the welding machine should be matched.
• Remote the nozzle from the gun and contact tip or protection cap and contact tip. Next, straighten the gun out flat.
• Insert the wire through the guide tube, over the roller and guide tube of Euro Socket into liner of gun. The wire can be pushed into the liner manually for a few centimeters, and should feed easily and without any force.

WARNING
If force is required it is likely that the wire has missed the liner of gun.

• Turn the welding machine on.
• Depress the gun trigger to feed the wire through the gun liner until the wire comes out of the threaded end.
• When trigger is released, spool of wire should not unwind.
• Adjust wire spool brake accordingly.
• Turn the welding machine off.
• Install a proper contact tip.
• Depending on the welding process and the type of the gun, install the nozzle (GMAW process) or protection cap (FCAW-SS process).
• Take precaution to keep eyes and hands away from the end of the gun while the wire is being come out of the threated end.

The 2-Step – 4-Step changes the function of the gun’s trigger

• 2 Step trigger operation turns welding on and off in direct response to the trigger. Welding process is performed when the gun’s trigger is pulled.
• 4-Step mode allows to continue welding, when the gun’s trigger is released. To stop welding, the gun’s trigger is pulled again. 4-step mode facilitates to   making long welds.

WARNING
4-Step does not work during Spot Welding.
The Burnback Time is the amount of time that the weld output continues after the wire stops feeding. It prevents the wire from sticking in the puddle and prepares the end of the wire for the next arc start.
Run-in WFS sets the wire feed speed from the time the trigger is pulled until an arc is established.
Spot Timer adjusts the time welding will continue even if the trigger is still pulled. This option has no effect in 4-Step Trigger Mode.

WARNING
Spot Timer has no effect in 4-Step Trigger Mode.
Preflow Time adjusts the time that shielding gas flows after the trigger is pulled and prior to feeding.
Postflow Time adjusts the time that shielding gas flows after the welding output turns off.

• Check condition and operation of the cooling fan.
  Keep clean its airflow slots.

• Periodic maintenance (every 200 working hours but at list once every year)

• Perform the routine maintenance and, in addition:

• Keep the machine clean. Using a dry (and low pressure) airflow, remove the dust from the external case and from the cabinet inside.

•  If it is required, clean and tighten all weld terminals.

• The frequency of the maintenance operations may vary in accordance with the working environment where the machine is placed.

• WARNING

• Do not touch electrically live parts.

• WARNING

• Before the case of welding machine will be removed, the welding machine had to be turned off and the power lead had to be disconnected from mains socket.

• WARNING

• Mains supply network must be disconnected from the machine before each maintenance and service. After each repair, perform proper tests to ensure safety.
