Frequently Asked Questions - Weldforce 160MST Weldclass
How do I set up the Weldforce 160MST for MIG welding?
Connect the MIG torch, earth clamp, and gas hose. Set the wire speed and voltage according to the wire diameter and material thickness. Refer to the chart on the machine for recommended settings. Ensure proper gas flow (typically 8-12 L/min for CO2 or mixed gas).
What type of gas is recommended for MIG welding with this machine?
For steel, use a mixture of 75% Argon and 25% CO2 (C25) or pure CO2 for deeper penetration. For stainless steel, a tri-mix (90% He, 7.5% Ar, 2.5% CO2) is common. Always use shielding gas suitable for the material.
How do I switch from MIG to TIG welding?
Disconnect the MIG torch and connect the TIG torch to the negative (-) terminal. Set the process selector to TIG. For DC TIG, use pure argon gas. Attach the earth clamp to the positive (+) terminal. Adjust the current as needed for the material thickness.
What does the anti-stick function do?
Anti-stick automatically reduces the welding current if the electrode (for Stick welding) sticks to the workpiece, preventing damage to the machine and allowing easier removal. This feature is especially useful for beginners.
How do I change the wire spool?
Open the side panel. Remove the spool retaining nut and old spool. Place new spool with correct orientation (wire feeds from bottom). Feed wire through the guide tube and into the drive rolls. Adjust tension with the knob. Replace the nut and close the panel.
What is the duty cycle of the Weldforce 160MST?
The duty cycle is 60% at 160 A (meaning you can weld for 6 minutes in a 10-minute cycle at maximum output). At lower currents, the duty cycle increases. Exceeding the duty cycle can trigger thermal overload protection.
Why is the wire feeding inconsistently?
Check the drive roll pressure (adjust if too tight or loose), ensure the wire spool spins freely, clean the liner of debris, and replace worn contact tips. Also verify that the wire diameter matches the drive roll groove.
Can I weld aluminum with this machine?
For MIG welding aluminum, you need a spool gun (not included) and pure argon gas. The Weldforce 160MST can handle aluminum up to ~3 mm with proper setup. For TIG, aluminum requires AC TIG which this machine does not support (DC only).
What safety precautions should I take when using this welding machine?
Always wear a welding helmet with correct shade (e.g., shade 10-13 for these currents), flame-resistant clothing, and gloves. Work in a well-ventilated area or use fume extraction. Disconnect power before maintenance. Keep flammable materials away.
Where can I find spare parts for the Weldforce 160MST?
Weldclass offers spare parts such as contact tips, nozzles, liners, wire drive rolls, and power boards. Contact Weldclass support or authorized distributors. The machine is designed for easy repair with replaceable modules.
