If the mold volume is too small, should also achieve as far as possible also adsorbs. 3. the magnet and the mold contact face maintain clean, guarantees the good breakover. The copper sheet surface adsorbs the impurity to remove, the mold surface adsorption magnet place has the greasy dirt either the oxide compound cleans up with the petroleum or the emery cloth. 4. magnet adsorption site choice: Is as far as possible near with the damage place straight distance, and smooth, and the magnet contacted area is big.

Before the patching, prepares:

One. Puts through the power source (220V, single-phase 50HZ)

Two. Connection magnet:

1. Makes an effort to screw tight magnetism iron wire on the main engine cathode output connection column.
2.2 magnets essential simultaneously adsorb on the mold. If the mold volume is too small, should also achieve as far as possible also adsorbs.
3. the magnet and the mold contact face maintain clean, guarantees the good breakover. The copper sheet surface adsorbs the impurity to remove, the mold surface adsorption magnet place has the greasy dirt either the oxide compound cleans up with the petroleum or the emery cloth.
4. magnet adsorption site choice: Is as far as possible near with the damage place straight distance, and smooth, and the magnet contacted area is big.

Third, connection sealed end:

1. Screws tight the sealed end ties effort in the main engine positive electrode output connection column.
2. According to the damage surface's actual situation choice different shape's red copper sealed end, and may carries on the right amount processing to the red copper sealed end shape, after the attention processing, the shape and the mold contacted area do not be oversized. (reference mold patching attention question 2)
Attention: In the work process, magnetism iron wire and the welding torch line's migration will screw tight the wiring column will pull the pine, will create the wiring column ablation, will affect the patching effect, should inspect frequently, screw tight.

Four. Inserts the foot pedal controlling switch

Five. The adjustment power, the choice makes up the material:

⑴Makes up the material outer covering according to each kind to show the power data adjustment main engine power, the flaky material power refers to the same thickness alloy steel.
⑵Different makes up the material according to the different molding tool steel choice of material (to for details see makes up material table)

Sixth, mold patching:

Unit process:

1) holds back the welding torch Yu Bucai the surface.
2) steps on puts one's foot down the switch.
3) rolls the welding torch.
4) loosens the foot controlling switch.
5) is separated from the sealed end and the mold.

Attention: If successively order wrong machine, although will report to the police the protection, but possibly occasionally will also melt the pit spot in the mold surface fever!

Matters needing attention:

⑴ Cleaning up: In needs patching place to make the simple cleaning up elimination greasy dirt and the impurity, otherwise has the circular telegram not harmonious sparks fly phenomenon in the patching process.

(2) trundle speed: The welding torch rotational speed in makes up on the material by the pulse output electric current to form a nodulizing reed of loom to list as suitably, the rotational speed cannot be excessively quickly, otherwise after patching polishing, has makes up the material peeling and the tiny blowhole phenomenon few.

(3) welding torch and mold contact point: The welding torch with makes up between the material a contacted area smaller pressure to paste is better, instantaneous through the current density is bigger (electric current to be more centralized), the spot quantity of heat is bigger, makes up the material union degree to be relatively good. Makes up the material outer covering to show the power data makes up when the material contact for φ5mm the standard welding torch graphite electrode and the plane the power request, the same power sealed end contacted area is bigger, the electric current is scattered, after making up, the effect is not ideal, otherwise, the contacted area is too small, patches in the process easy to create makes up the material melting splash and the superficial pits and depressions is uneven.

(4) posture and pressure: When patching the welding torch and the mold surface become 45 degrees to good, and exerts certain pressure to the welding torch, the pressure size decides according to the damage surface rough degree, is not smooth, impurity many surfaces make an effort suitably big.

(5) complex die space: Fine, when multi-edges and corners, complex plane patching with the precise power, the thin material patch many times to good, the conventional condition is suitable for the patching quantity quite big damage place.

(6) oxidized surface patching:

Process: Cleaning up impurity---> removes the oxide layer---> the edge patches with the low power---> levels---> polishes

before 1) oxidizes mold patching, to use the power tool elimination nitriding level first, will make up the material direct welding in the steel products parent metal, otherwise makes up between the material and the parent metal has the oxide layer to isolate, easy to flake.

2) patches the edge part to use the low power as far as possible, because the thin material, may reduce, the reduction to patch gives off heat produces the edge trace.

after (7) patching polishing, the addendum circle has breaks out lightly, produces the reason is when patching has the quantity of heat the work piece to create hardly, the quenching characteristic good material quality is especially obvious, the edge part uses the low power, thin material patching may avoid this kind of phenomenon (method reference oxidation mold patching).

after (8) patching polishing, in concave, has the reason is makes up the material to be lower than the parent metal to create hardly, selects degree of hardness and the parent metal makes up the material to be possible closely to avoid.

Seven. Routine maintenance

In order to cause your machine better to serve for you, should complete to machine's routine maintenance, this butt weld quality has the very tremendous influence. Because works pulse current for low pressure big electric current, therefore should the special attention terminal, the electric cable, the welding torch and the magnet copper sheet. Certainly must maintain between them is good with mold's electrical contact.

1) the magnet copper sheet wears the prompt replacement.
2) the electric cable like has breaks the stock obviously, should replace or the repair.
3) the welding torch interior should maintain clean, cleans up the impurity frequently.
4) inspects the positive and negative wiring column, the effort screws tight extremely, if has the ablation phenomenon to replace promptly.
5) patches in the process the welding torch to give off heat is the normal phenomenon, patches continually when applies two welding torches to use alternately, do not wrap the thermal insulation material outside the welding torch, will otherwise accelerate the welding torch damage.
