Electric arc welding is one of the strongest metal joining methods — perfect for gates, steel frames and pipework. Success depends on choosing the right electrode, setting the correct amperage and following basic safety rules. This guide walks you through every step for working in Israeli field conditions.
Quick Summary
✅ Match electrode type to metal (mild steel, stainless, pipe)
✅ Set current at 40-50 amps per mm of electrode diameter
✅ Clean metal of rust and paint before welding
⚠️ Always use welding mask and heat-resistant gloves
💡 Use a magnetic welding angle for perfect 45°/90° joints
What You Need Before Starting 🧰
Prepare: an inverter welder, welding electrodes for your metal type — for mild steel use HYUNDAI-11 or ZIKA Z10 (2.5mm for light work, 3.25mm for thicker joints), a 200A–300A welding clamp handle, a 300A–500A extension handle, a magnetic welding angle, chipping hammer, steel brush, welding mask, heat-resistant gloves and protective eyewear. For pipe welding use ZIKA Z610 with deep penetration.
⚠️ Important Before Starting
Never weld near gas, fuel or flammable materials. Welding fumes contain hazardous particles — always work in well-ventilated areas or outdoors. A UV-filter welding mask is mandatory, not optional.
Step by Step — How to Weld Correctly 👷
Step 1 — Surface Prep: Remove all rust, paint and grease with a steel brush or grinder. Dirty metal causes weak joints and porous welds.
Step 2 — Electrode Selection & Current: For mild steel 3–5mm thick, use HYUNDAI-11 2.5mm at 80–100A. For 6–8mm, use 3.25mm at 110–130A. For pipe work, ZIKA Z610 at 90–120A.
Step 3 — Clamp & Position: Use the magnetic welding angle to hold pieces at the correct angle. For long joints, tack-weld (short spots) before running the full bead.
Step 4 — Strike the Arc: Hold the electrode at 70–80° to the work surface. Maintain a 2–3mm arc length after striking. Move steadily along the weld line.
Step 5 — Run the Bead: Travel in a straight or slight zigzag motion. Keep consistent arc length (2–4mm). Uniform travel speed = flat, strong weld.
Step 6 — Remove Slag: After 30–60 seconds cooling, chip away the slag layer with a chipping hammer. Clean with a steel brush and inspect for cracks.
Step 7 — Inspect Quality: A good weld is uniform, with no porosity or undercuts. If the arc is unstable — check current setting, surface cleanliness and electrode condition.
💡 Pro Tip
Store electrodes in a sealed box with silica gel sachets. Moisture makes electrodes 'wet', causing unstable arc and porosity in the weld. Dry electrode = smooth bead.

What's the difference between HYUNDAI-11 and ZIKA Z10 electrodes?
Both are rutile electrodes for mild steel. HYUNDAI-11 is ideal for general work and beginners — stable arc, easy to control. ZIKA Z10 has an improved coating for a smoother bead and is better for precision work.
What current for a 2.5mm electrode?
Set 70–90 amps for a 2.5mm electrode in general welding. The rule: ~40 amps per mm of electrode diameter. Start low and increase as needed.
Why is my arc unstable and sputtering?
Three common causes: damp electrodes (store dry), dirty metal surface (clean before welding), or current set too low. Try increasing by 10A and check.
