Description
A welder earns its place by what it can join on a Tuesday afternoon. The bestarc MIG145 is a 3-in-1 machine covering gas MIG, gasless flux-cored MIG, lift TIG and stick, so a repair job does not wait for a second machine to be delivered. It runs on 220 V single phase, which is the supply most workshops, garages and farms already have, and it welds stainless steel, carbon steel and thicker stock with a 145 amp ceiling.
The front panel carries a digital display for current and settings, and the wire feed accepts 0.030, 0.035 and 0.040 inch flux-cored wire alongside 0.030 inch solid wire, so a spool change covers sheet metal through to structural sections. Setup is deliberately short: select the process, set the current from the display, and the machine handles the rest. Gasless operation means a beginner can run flux-cored wire outdoors where shielding gas would blow away, and switch to gas MIG for clean indoor welds when the job calls for appearance as much as strength. The lift TIG and stick modes extend the same box to thinner precision work and to rod welding on site.
For a fabrication bench, a repair bay or a farm workshop, one 220 V unit covering four processes removes the arguments about which machine the job needs.
Metal does not care how many machines you own. It cares whether the joint holds.

Application Scenarios
Small fabrication shops use the MIG145 as the everyday machine for brackets, gates and repairs, moving between gasless flux-cored wire outdoors and gas MIG on the bench. Farms and rural properties rely on stick mode for field repairs where gas cylinders are impractical. Automotive enthusiasts use lift TIG for thin panel work and stainless exhaust fabrication. Trade schools and training workshops favour a single machine covering four processes, which keeps the teaching bench uncluttered and the settings comparable across students.
Frequently Asked Questions
Q: Can I weld without shielding gas?
Yes. The machine runs gasless flux-cored MIG, which is the practical choice for outdoor or draughty work, and switches to gas MIG for cleaner indoor welds.
Q: What wire sizes are supported?
0.030, 0.035 and 0.040 inch flux-cored wire plus 0.030 inch solid wire, which covers thin sheet through to thicker sections.
Q: Is the TIG torch included?
The TIG torch is shown for installation demonstration only and is not part of the standard package. The machine itself supports lift TIG when a torch is fitted.
Q: What power supply does it need?
The unit runs on 220 V single phase with an EU plug, which matches most workshop and garage supplies.
Q: What materials will it weld?
Stainless steel, carbon steel and thicker steel can be welded with the 145 amp output, with the process chosen according to thickness and finish requirements.
Q: Is the MIG145 suitable for someone new to welding?
The gasless flux-cored mode removes shielding gas handling entirely, and the digital display shows the setting in use. That makes the first welds far easier to control than a stick-only machine on thin material.
Q: How do I change between welding processes?
Process selection is made from the front panel, with the digital display showing the current applied to the wire or electrode, so gas MIG, gasless MIG, lift TIG and stick share one control layout.
