NOTE: The feed roller has two depressions, one for 0.6 mm width wire and one for 0.8 mm measurement wire. Be certain that the right depression size is accurately matched to the welding wire being utilized. To invert the roller, unscrew the two screws getting the roller supporting section and eliminate the section. The roller can now be taken off the drive shaft and turned around. Reinstall the roller supporting section and secure with the two screws.

Obligation Cycle:

Welder obligation cycle is the level of genuine weld time that can happen in a brief span.

For instance, at a 20% obligation cycle, real welding can happen for two minutes, and afterward the welder should cool for eight minutes.

Thermostatic Protection:

Inside parts of this welder are shielded from overheating with a programmed warm switch. A yellow light is enlightened on the front board in the event that the obligation cycle is surpassed. Welding activities might proceed with when the yellow light is not generally enlightened.


Switch welder OFF and turn off from power source during groundwork for welding. Check that the surfaces of metals to be joined are liberated from soil, rust, paint, oil, scale or different impurities.

These impurities make welding troublesome and cause helpless welds. Associate the work cinch to the work piece. Ensure the contact is on uncovered metal and not hindered by paint, stain, erosion, or non-metallic materials.

Set the amperage change selector to the ideal setting. Allude to the diagram underneath for appropriate result current settings. Set wire speed by turning wire speed control handle to the center position.

NOTE: Switching the result current from one setting to the next consequently increments and diminishes the comparing wire speed. The wire feed speed setting control gives fi ne tuning on a case by case basis after test welding.

Plug power rope into an appropriate electrical plug as determined in the ELECTRICAL REQUIREMENTS part of this guidance manual. Switch welder power change to the ON position.

Guarantee welding wire distends 1/4 inch from the finish of the contact tip. If not, crush trigger to take care of extra wire, discharge trigger and slice wire to address 1/4 inch length.

Position welding light close to work piece and lift hand safeguard to ensure your eyes. Crush firearm trigger to actuate welder. Change heat setting and wire speed depending on the situation.

While welding, continue to weld light travel at a steady speed and keep a cathode length (distending welding wire) of 1/4 inch Follow the right heading of movement for the joint kind and direction itemized in the WELDING GUIDELINES part of this manual.

To quit welding, discharge weapon trigger. At the point when completed the process of welding, switch welder off and store appropriately


Prior to each utilization:

Really look at state of welding links and promptly fix or supplant any links with harmed protection. Check state of force line and promptly fix or supplant any rope whenever harmed.

Check state of welding light tip and spout. Clean to eliminate any aggregated slag to try not to connect between the spout and contact tip.

Spanning causes abbreviated spouts, helpless welds and overheating of the weapon. Supplant welding light tip or spout whenever harmed.

Like clockwork, or all the more habitually with weighty use:

Supplant any incoherent names on the welder. Utilize compacted air to blow all residue and soil from the ventilation openings. Vacuum soil from wire compartment.

Clean notches in wire feed drive roll. Eliminate wire from component and eliminate two screws from drive roll lodging. Eliminate drive roll and clean with a little brush. Supplant harmed or worn drive roll depending on the situation.

Examine the approaching rounded wire feed guide and clean within tube if necessary. Clean the weapon liner by eliminating the spout and contact tip. Clean within distance across of the welding light with a short piece of wire.

Clean the link liner by spreading the link out straight and extinguishing the liner tube with spotless, dry compacted air. Flex the link this way and that, and afterward blow the cylinder out once more.

Rehash this interaction until the liner tube is perfect. Supplant worn liner tube depending on the situation. Supplant contact tip assuming opening is expanded or sporadically formed.

Consumable and Wear Parts:

The accompanying parts require occasional upkeep:

  • Wire feed drive roller – Replace whenever worn or harmed
  • Weapon liner – Replace whenever worn or harmed
  • Spout – Replace depending on the situation

  • Wire – This welder acknowledges 4 inch breadth spools of transition cored welding wire. AWS E71T-GS or E71T-11 transition center wire is suggested for welding gentle steel.

Figuring out how to Weld:

Welding is an expertise that requires practice and, similar to any new ability, can’t be dominated without experience.

The accompanying data is intended to assist the unpracticed welder with understanding the essentials of motion wire welding.

It’s anything but a substitute for training and isn’t planned to fill in as the main data asset for the starting welder.


This welding machine uses an interaction known as Flux Cored Arc Welding (FCAW). This interaction is utilized to bond metals by warming them with an electric bend made between the wire anode and the work piece.

The wire terminal utilized for transition cored curve welding has two sections. The external mass of the wire anode is comparative in arrangement to the base metal with an inward center loaded up with transition. While the metal is liquid, it very well may be tainted by components in the air. This defilement could debilitate the weld.

The transition makes a safeguarding gas when liquefied which frames a defensive boundary called slag that shields the liquid metal from toxins. At the point when current (amperage) moves through the circuit to the wire anode a curve is shaped between the finish of the cathode and the work piece.

The circular segment liquefies the wire and the work piece. The liquefied metal of the cathode wire streams into the liquid hole and structures a bond with the work piece as displayed beneath.

Striking AN ARC:

Be certain the work clip is appropriately joined to the work piece. Position firearm over joint to be welded. The finish of the wire may daintily contact the work piece. Position hand safeguard to ensure face and eyes, crush trigger and start welding.

Hold weapon with the goal that the contact tip is around 1/4 inch to 1/2 inch from the work piece. To quit welding, discharge the trigger and threaten to use the weapon away from the workpiece after the curve goes out.

NOTE: Should a ball structure toward the finish of the wire subsequent to welding, feed out a short length of wire and trim the wire to with.
