Welding and soldering equipment for HGV workshop use
MIG welding is the standard process in HGV bodywork repair and chassis fabrication. The process combines ease of use with good penetration on the steel sections typically encountered in truck and trailer repair: box sections, subframes, and body pillars from 1.5mm sheet up to 10mm plate. A workshop MIG welder in the 130A to 200A range covers the majority of HGV bodywork applications.
For heavier structural work including chassis cross-members, fifth wheel mounting plates, and axle subframes, a higher-output MIG or MMA (stick) welder gives better penetration and weld quality on thicker sections. These jobs require correct welding procedure and material identification: welding on safety-critical chassis components without the correct process and consumables creates a risk that will be identified at DVSA annual test.
Soldering equipment is used primarily for auto electrical work: repairing connectors, splicing wiring looms, and installing connectors in areas not suited to crimp tooling. For electrical soldering in vehicle applications, use rosin-core solder rather than acid-flux solder, as acid flux causes long-term corrosion in electrical joints.

Frequently Asked Questions
What MIG welder output do I need for HGV bodywork repair?
For most HGV bodywork repair and light fabrication work on steel sheet and sections up to 4mm, a MIG welder with a rated output of 130A to 180A is sufficient. For heavier sections including chassis brackets and body pillars above 5mm, a welder rated to 200A or above gives better penetration. Check the welder's duty cycle: a 60% or higher duty cycle at maximum output is appropriate for workshop use.
Can I weld HGV trailer panels with a standard MIG welder?
Yes, for steel bodywork panels and framework. Modern refrigerated trailer panels often use aluminium or composite construction, which requires TIG or aluminium MIG welding rather than standard steel MIG. Confirm the panel material before starting. Attempting to MIG weld aluminium with a steel wire setup will not produce a sound weld.
What soldering equipment do I need for HGV auto electrical work?
A temperature-controlled soldering iron or soldering station rated to 50W is the correct choice for auto electrical work. Variable temperature control allows you to work on both heavy multi-strand cables and fine connectors without burning insulation. Use rosin-core solder: acid-flux solder causes corrosion in electrical joints over time. Solder wick and a desoldering pump are useful for rework.
Do you stock welding consumables for workshop use?
Yes. We stock MIG welding wire, welding rods for MMA, and soldering consumables including rosin-core solder and flux. MIG wire is available in 0.6mm and 0.8mm diameters for sheet metal work, with 1.0mm wire for heavier sections. Call us on 01527 598 000 to confirm current stock on specific consumables.
