precise mould cold welding machine

SZ-1200 cold welding machine to repair stainless steel, mould, crack, holes, with full set of accessoires, include welding wire / electrode

1. Applications and introduction:
1. Welding injection mold, stamping mold, casting mould, rubber mould, copper and aluminum alloy mold, etc. After repairing / welding, all mould can be used for all kinds of mechanical processing, thermal treatment and nitrogen treatment.
2. Repair work pieces, parts, tools: like all kinds of gears, rodents, valve, cylinder, machine tools.
3. Soldering thin stainless steel plate, such as stainless steel table-board, tube together.

SZ-1200 welding sheet function (welding together):

This welding machine can soldering/ welding 0.3-1.6mm sheet/ thin plate. The welding application like: advertisement letter welding, cabinet sheet welding, stainless steel window & door welding, bathroom fixture sets welding, stainless steel table-board welding, warehouse work pieces welding, etc.

Characters of SZ-1200 for welding
1. Small heat affected zone while welding
2. No need preheating processing, no need annealing for the work pieces after welding
3. No deformation and edge after welding.

4. No air hole and sand holes after welding.
5. Precise and accurate: can weld very small and precise part, the finest wires used for welding can be 0.10mm-0.20mm
6. It is convenient and flexible for welding, site repair is also available.
7. Widely used in repair all cracks, sand holes, collapse edges, corners, abrasion, etc.
8. It is also available welding the toughing mouth of cold dies and tools. Thus exempt from the preheating, heat preservation process of ordinary arc welder.

2.Machine & accessories pictures:

Accessories list: ( electrode/ welding wire will also be provided as pictures showed)

Accessories will be packed in one aluminum case for better protection:

<img Consumable material is welding wire/ welding electrode; different material need different welding electrode:

Welding electrode like SKD-11, H13, some stainless steel electrode, etc:

We will provide a full set of accessories for you, you only need rent a bottle of argon for protection in welding:

Adjust argon figure and connect the argon connector to the argon:

3. SZ-1200 welding/ repairing function:
Injection mould: Defects like wear out, bruising, scratches, hole, etc, eliminate products' flash, burr, etc.

Die casting mould: Defects like etch, loss, damage, wear out, chap, fracturing, etc

Auto parts casting: automotive crankshaft, piston, cylinder, wheel hub, brake disc, clutch, exhaust pipe casting defects (such as sand hole, porosity, cracks).

Industrial machinery and machine tools: repair size tolerance or wear work pieces, such as repair machine guideway, large mechanical shaft, gear parts; hot roller, cold roller, hydraulic rod in engineering machinery, printing cylinder, and all other metal components parts defects.

Aviation and shipping manufacturing: Repair/ weld compressor shell, stainless steel precision parts, precision shaft and valve, etc

And other many industry and metal products welding/ repairing.
