Frequently Asked Questions - WeldSkill 350 MIG Cigweld
What is the recommended shielding gas for the WeldSkill 350 MIG?
The recommended shielding gas is a mixture of 75% argon and 25% CO2 (C25) for mild steel. For stainless steel, use a tri-mix (90% He, 7.5% Ar, 2.5% CO2). Pure CO2 can also be used but may produce more spatter.
How do I set the wire feed speed and voltage?
Refer to the welding parameter chart inside the machine door. Start with the recommended settings for your wire diameter and material thickness. Adjust voltage for arc stability and wire feed speed for desired weld bead appearance. A good rule: listen for a steady crackling sound.
What is the maximum material thickness I can weld with this machine?
With a single pass, the WeldSkill 350 MIG can weld up to 12 mm (1/2 inch) mild steel. For thicker materials, bevel the edges and use multiple passes. Preheat may be required for thick sections.
How do I troubleshoot wire feeding issues?
First, check the wire spool for tangles. Ensure the drive roll tension is correct (not too tight or loose). Clean the liner and replace if clogged. Also verify that the contact tip is not worn or blocked. Common causes: wrong size liner, kinked torch cable, or debris in the conduit.
What maintenance does the WeldSkill 350 MIG require?
Regularly clean the air intake vents to prevent overheating. Inspect and replace contact tips, nozzles, and liners when worn. Lubricate the wire feed mechanism per the manual. Check all electrical connections for tightness. Periodically drain any moisture from the gas hose.
Can I use flux-cored wire without shielding gas?
Yes, the machine supports flux-cored arc welding (FCAW) with self-shielded wire. Use the correct polarity (usually DCEN for self-shielded flux-cored). Remove the gas hose and set the gas solenoid to off. Ensure the wire is designed for self-shielding.
What is the duty cycle and why is it important?
The duty cycle is the percentage of time you can weld in a 10-minute period without overheating. For example, 60% at 350A means you can weld for 6 minutes then cool for 4 minutes. Exceeding the duty cycle may trigger thermal overload and damage the machine. Always respect the duty cycle for your selected current.
How do I change the polarity for gasless wire?
Open the side panel. Locate the welding cable connections inside. For standard MIG (solid wire with gas), connect the torch to the positive (+) terminal and the work clamp to the negative (-). For self-shielded flux-cored (gasless), reverse the connections: torch to negative (-) and work clamp to positive (+). Consult the manual for your specific wire brand.
The machine keeps tripping the breaker. What could be wrong?
Check if the input voltage matches your supply. Ensure the circuit breaker is rated for the machine's maximum input current (e.g., 25A per phase). A faulty internal component like a rectifier or transformer could cause a short. Also verify that the machine is not being operated beyond its duty cycle, causing excessive current draw.
Where can I purchase spare parts for the WeldSkill 350 MIG?
Spare parts are available through authorized Cigweld dealers and many welding supply stores. Common consumables like contact tips, nozzles, liners, and drive rolls are widely stocked. You can also order online from Cigweld distributors. Always use genuine Cigweld parts for optimal performance and safety.
