Hints and Tips for Using GYS MULTIWELD 400T G 1 MIG Welder Package
Take time to set up your wire feeder
Before starting a job, ensure the WF 20 wire feeder is correctly set up with the right wire diameter and tension. A well-adjusted wire feed helps improve arc stability and can make welding feel smoother and more controlled.
Use the front-panel welding guide as a starting point
The welding chart on the front of the machine is a helpful reference when setting voltage and wire speed. It’s a great place to start, especially when switching between material thicknesses or wire types.
Experiment with 2T and 4T trigger modes
If you’re working on longer welds, 4T mode can help reduce hand fatigue by allowing you to weld without holding the trigger continuously. For shorter welds, 2T mode often feels more intuitive.
Keep aluminium welding consistent
When welding aluminium, make sure your torch liner, rollers and wire are suited for aluminium use. This can help reduce feeding issues and improve overall weld appearance.
Make use of gas pre-flow and post-flow settings
Adjusting gas purge and post-gas time can help protect the weld pool and reduce oxidation, particularly on stainless steel and aluminium. Small adjustments here can make a noticeable difference.
Maintain good workshop organisation
The built-in storage and low-profile gas bottle support are there to make daily use easier. Keeping cables tidy and accessories stored correctly can help extend their lifespan and improve safety.
